I am new to IBM worklight.I have created a application using Dojo mobile,Dragged and dropped the widgets into Rich Page Editor but when I run the app or check the result in preview,the widgets are not getting displayed
Technically it shouldn't create any issue unless until something goes wrong, try to open the browser console, there must be something fishy which creating the issue.
If possible share the code to debug the issue otherwise it's tough to provide any pointers without having use case.
Open your mobile app in a JavaScript Debug Environment (Firebug) and look for errors!!!
It could also be possible that the dojo.parser is not running. You can trigger that manually by doing the following:
Configure your application that dojo-parser wont get invoked automatically.
<script type="text/javascript" src="dojo/dojo.js"
data-dojo-config="parseOnLoad: false">
</script>
Trigger parser after dom-ready event got fired.
require(["dojo/parser", "dojo/ready"], function(parser, ready){
ready(function(){
parser.parse();
});
});
In dojo, it won't render in the preview (not correctly if it does). Try to download the Android SDK and run it on the emulator. I have had the same issue with the browser simulator and Dojo mobile in a few apps. I don't use it often, but I haven seen the issue.

I have got an angular project generated with yeoman/generator-angular with both mobile and desktop views. The mobile templates heavily rely on mobile-angular-ui and it works just fine in development.
For some reason the modals are not displayed after grunt build. Instead, calling a modal would act as if a transparent component was added on top of the page (I mean, with the highest z-index), stealing the focus in the same way that a modal would do. As a consequence, the modal itself is not displayed and the page does not respond to any click event (assuming the fake modal is locking the focus).
The content of my modals is loaded via ng-include directives and it seems to work (from what I can see in the network tool of Chrome). There are no error message complaining about a missing resource in the console and the only thing I can think of is that the code responsible for toggling the modals visibility in mobile-angular-ui was somehow impacted by the build process. Sounds possible?
Any idea of what could cause this difference of behaviour between dev and production?
I am using mobile-angular-ui 1.2.0-beta.11. Feel free to request more information.
Bingo. The problem actually came from a clash between mobile-angular-ui and bootstrap, as I was using both of them for the mobile and desktop views respectively.
Since I use a very limited subset of bootstrap, I decided to remove all my bootstrap dependencies and only work with mobile-angular-ui which also provides a minimalist support for desktop views (namely col-md-xx etc. for responsive layouts).
I don't know about mobile-angular-ui, but in Angular ui-bootstrap you need to include not only the main code but also the templates:
<script src="bower_components/angular-bootstrap/ui-bootstrap.min.js"></script>
<script src="bower_components/angular-bootstrap/ui-bootstrap-tpls.min.js"></script>
When you don't include the tpls, the development is still working, because it's able to load the files from their location in bower_components.
In production you get a similar result as you describe when using modals, because the templates were not bundled in your dist directory. Maybe it's a similar problem?
I want to create an angularjs app but each time it requires to press the refresh button in the browser to get the update. thus it bring to this question:
Is there any way to get live update while writing angularjs app? So I don't need to press the refresh button each time I make changes in my angularjs app.
Yes, you can use grunt which is a task runner written in node, grunt has a plugin called grunt-contrib-livereload that reloads the page whenever there are changes in the files/directories that you want to watch. Alternatively, there's a scaffolding tool for client side web applications in AngularJS called yeoman, that has a generator called generator-angular - this generator has an opinionated structure towards AngularJS application development and it comes with a basic setup that you can use for livereloading code changes from any files that you have configured to watch.
Start using yeoman. It has grunt that will solve yr problem plus lots of more exciting stuff.
Check this quick start guide : http://yeoman.io/learning/
I use the open source editor Brackets.io by Adobe. Just click the lightning icon button to the right of the editor to run your web page and will auto refresh for every save.
You can do this in many ways. Many of the options are already mentioned in this post. All of them are workable. In my experience the most simplistic way to do this by the following way.No configuration , No setting , No need to code anything.
Just add this line in your <head> </head> tag of the html file
<script src="http://livejs.com/live.js"></script>
I've ran into an issue with Safari on iOS 5.1.1 and Angular where I am doing paginated results. After I decide to leave the page that is hosting the app, and then come back to the page by using the browser's history back button.
The application is not initialized so as I scroll again, the pagination functionality is not triggered.
Since 5.1.1 doesn't provide a web inspector, I had to rely on console.log to print events that I want to see that it's executing. On initial load, I see everything ok, but when I am back through the back button nothing fires.
My usual ways of fixing this are not working. Here are the things I've tried:
Used manual bootstrapping of Angular app
Made the page not support caching and expire the page as soon as it's rendered.
Neither of these helped, which is why I am here asking for some suggestions. Unfortunately it's not a very easy thing to replicate through a Fiddle or a hosted HTML file so I am unable to provide one. Hoping that some of you may have experienced this before.
Thanks in advance for any help.
Answer is quite late and I hope you found a solution already but it might be useful for others.
Unfortunately I won't be able to answer why the app is not initialized (due to the lack of code) but I can give you some tools/tips to ease the debugging (assuming you have the iOS simulator).
Debuging on mobile safari can be done either :
with weinre and get the features of the web concole,
or by enabling remote debugging in Mobile Safari itself, see here
Yea, same problem here with iOS 7. It must send the DOM structure over before running any javascript. Kinda pointless...
Since the problem is with mobile safari and since it supports popstate event, you can use this event to detect when the user is back in combination with $location.path(), for example:
$(window).bind("popstate", function () {
alert(location.pathname + $location.path());
});
I have a bunch of components that I am calling setValue on, everything is working fine in all browsers except the Android web browser and google chrome for android. Has anyone seen this behavior or knows how to solve it? I don't know where to really begin.
Ok you have to enable Javascipt for the Web View as android disables JS by default due to security reasons
YourWebView.getSettings().setJavaScriptEnabled(true);
YourWebView.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
That should so the trick
if your app has secure data you probably don't want 3rd party software running JS in your app
Hope this helps
UPDATE: There is a workaround to the problem. It is to force IE10 into compatibility mode by including one of the following meta tags:
<meta http-equiv="x-ua-compatible" content="IE=7" />
<meta http-equiv="x-ua-compatible" content="IE=8" />
This is not really a perfect solution for various reasons, but it eliminates the problem at least.
ORIGINAL QUESTION:
I realised a couple of months ago that there is a problem with our Silverlight application in IE10 on Windows 8 (I have not tried the IE10 preview for Windows 7). When the asp.net page hosting our SL app first loads everything works fine and the application loads as expected. If I refresh the page immediately, it also reloads as expected. But: If I focus the Silverlight application by clicking in it and THEN hit F5, it just goes blank. It is like the plugin disappears completely. If I trace the requests using Fiddler I can see that no request is issued for the xap file. I have been hoping that this would be fixed in a patch release for IE10, but so far nothing has changed. I cannot find any information about this when I try googling it. It seems highly unlikely that I should be the first person to discovered it and I am quite surprised that I am not finding more information. To reproduce the issue:
Create a new Silverlight application
Add some sort of content to MainPage.xaml, like a Button or whatever
Run the app in IE10 (on Win8)
Click anywhere within the Silverlight application. This is just to focus the plugin.
Refresh the page (F5)
Result: The Silverlight application does not load and the page is blank.
A few observations:
After the steps above, no amount of refreshing will bring the application back.
After the steps above, if I re-enter the url into the address bar and hit Enter, the application loads as expected.
If I enable Compatibility View in IE, the app also loads as expected. Nothing I do will reproduce the bug when compatibility view is enabled.
Now to my questions:
Has anyone else observed this behaviour?
If so, have you found a workaround?
I'm seeing the same issue with my Silverlight application in IE 10.
I've tried adding the IE 8 compatibility meta tag suggested above, but this does not resolve the problem consistently. It seems to work only intermittently, after say every 5th refresh attempt?!
The only way I can see to work around this consistently is to force the Browser Mode into "IE 10 Compatibility View", and I don't think this can be done via page content (meta tag, etc.)? I've had to remove the IE 8 compatibility meta tag so that the "Compatibility View" button is available in the address bar, and then ask users to click the compatibility button, which is then remembered for the site. This results in the browser entering Browser Mode: "IE 10 Compat View" and Document Mode: "IE7 Standards". The refresh behaviour then works consistently as expected and as it used to.
This is a big problem for us. We've built our Silverlight app such that the browser refresh button is used to refresh pages/content within the app (the users stays logged in, etc.). It's really bad that we have to ask users to set our site to run in compatibility mode for the refresh functionality to work as expected.
Note that this still works as expected in Chrome. It seems silly that we might need to recommend that our users use Chrome because of this issue!
UPDATE:
A workaround for this seems to be to always load the Silverlight object into its hosting page dynamically using JavaScript.
E.g.
function onLoad() {
var silverlightControlHost = document.getElementById("silverlightControlHost");
silverlightControlHost.innerHTML = "<object ...
UPDATE 2:
Here is the latest code I use to work around this issue:
...
function unloadSilverlight() {
document.getElementById("silverlightControlHost").innerHTML = "";
}
function focusOnSilverlight() {
document.getElementById("silverlightObject").focus();
}
function onLoad() {
window.onbeforeunload = unloadSilverlight;
setTimeout(focusOnSilverlight);
}
</script>
</head>
<body onload=" onLoad() ">
...
I still had issues with the solution presented by Chris.
This works perfectly for me though:
window.onbeforeunload = function () {
var silverlightControlHost = document.getElementById("silverlightControlHost");
silverlightControlHost.innerHTML = "";
}
I solved the problem in a very easy way. I Wrote a javascript code at the end of the page (or after the object tag in where is your silverlight app) and set the focus to another element, for example, a link. Example:
<object id="silverlightHostControl">...bla bla bla</object>
<script type="text/javascript" language="javascript">
var shc = document.getElementById("silverlightHostControl");
document.getElementById("myLink").focus();
</script>
The shc var is useless, I put just for clarify. Remember: your javascript code must set the focus to another (but focusable) object AFTER the silverlight app object tag was parsed, which means your js code is writen after silverlight app object.
In answer to your question #1, this is happening with our Silverlight apps as well. The only workarounds are 1) restart the browser or 2) switch to compatibiity mode.
It apparently is a bug in ie10.
Thanks for all workarounds solution but this is obviously a bug with Silverlight plugin.
We have raised few tickets directly with Internet explorer development team and they said the issue is from an external problem. It is not a good answer from Microsoft.
Anyway, this time our developers raised ticket through Silverlight development team which still waiting for their response. To get a good response from them, we need to get more people who are facing this issue.
You can vote this issue from Connect website which is Microsoft's official bug reporting platform.
The link to our ticket is: http://connect.microsoft.com/VisualStudio/feedback/details/789004/ie10-shows-blank-page-upon-refreshing-silverlight-app

Yeah i am also facing same issue with one my application. If i opens help of my application in IE 10 then i have to refresh the page each time to view the contents.
I have two workaround for this issue:
1. Press ALT key once
2. Open IE in compatible mode
