I'm trying to include a Lightning component in VisualForce page. I'm experiencing two issues. Here's my code.
CreditCard.app:
<aura:application access="GLOBAL" extends="ltng:outApp">
<aura:dependency resource="c:CreditCardForm"/>
</aura:application>
ISSUE 1:
If I include extends="ltng:outApp", I'm getting an error saying "Something has gone wrong. $Lightning is not defined". I'm able to preview the app if I remove that piece of code. What exactly is the reason for this?
ISSUE 2:
I'm trying to access the CreditCardForm component in Visualforce page. The code is below:
<apex:page >
<apex:includeLightning />
<div id="lightning"/>
<script>
$Lightning.use("c:CreditCard", function() {
$Lightning.createComponent("c:CreditCardForm",
{},
"lightning",
function(cmp) {
// do some stuff
});
});
</script>
</apex:page>
To include Lightning component in VF page, extends="ltng:outApp" needs to be included according to documentation. However, even after including that, the page is empty. Please suggest a solution. TIA.
For the issue 1 ,You will not be able to preview .You will have to use Visualforce page to preview your component .
If you want to preview your component ,use another app where you can insert the aura component .
The second seems to be issue with your component not rendering anything .You can download lightning inspector and debug the issues .

The page loads without any of the images displaying on IE11 only, but refreshes them accordingly when we resize the browser intermittently (1/3 loads). We cannot replicate this with any of the other browsers. srcset works fine by itself with static content.
Here is a Plunker example of it not working in IE11.
Or quick and easy, the actual img html we're using:
<img data-ng-srcset="{{::image.url}}, {{::image.url2x}}" alt="{{::image.name}}"/>
The images or surrounding divs do not have any transitions, shadows or opacity applied.
The html renders fine with angular passing over and rewriting the srcset attribute correctly. The images just do not appear, only the alt tag. Wondering if this could be a call stack issue due to the intermittence of it, maybe a race condition with Picturefill loading before angular finishes a digest or something.
Cheers in advance!
A work around if you use PictureFill in a loop and in a specific case (not on all images of your application), is calling a function that launch PictureFill directly from HTML, after last item loaded (this is not the best practice but fix the IE11 problem) :
<picture><!-- Your image --></picture>
<span ng-if="$last">
{{ controllerAlias.launchPictureFill() }}
</span>
Came across this as a solution: http://tech.endeepak.com/blog/2014/05/03/waiting-for-angularjs-digest-cycle/
var waitForRenderAndDoSomething = function() {
if($http.pendingRequests.length > 0) {
$timeout(waitForRenderAndDoSomething); // Wait for all templates to be loaded
} else {
$window.picturefill();
}
}
$timeout(waitForRenderAndDoSomething);
The only issue that the blog post describes is here, so if anyone has anything better please let me know:
The $http.pendingRequests supposed to be used for debugging purpose only. If angular team decides to remove this, you can implement the same using http interceptors as suggested in this link.
How can I show a spinner or loader gif animation while route is changing from one to another.
I am using ng view like as follows:
<div ng-view class="view-animate">
</div>
I am loading templates from server and also inline. While the HTTP request is pending I need to show the spinner/loader... any snippets?
You can show and hide the loader when location change starts and is completed, respectively.
Here is a plunkr that I have created for this situation. This uses ui-router and is taken from one of the apps that I have created, so it may not be useful as-is, but it will give you an idea on how to approach the problem.
HTML Code inserted below just to keep SO happy...
<ui-view class="view"></ui-view>
<div loader="" class="ng-hide"></div>
I hope it helps.
Abhi.
I'm new to Salesforce/Apex and I need to be able to test a component I am working on in a separate page.
Here is the scenario. I have the following test page:
<apex:page sidebar="false" showHeader="false" standardController="Contact">
<div id="wrapper" style="max-width:980px;">
<c:djEmailTemplate_MainComponent sObject="{!Contact}" theContactId="{!Contact.Id}"/>
</div>
</apex:page>
I can display the page by adding /apex/testpage to the url after the project name.
What I don't know how to do is to include data to satisfy the parameters (sObject, theContactId) that are needed to populate values in the component.
Can anyone explain how I can do this?
Thanks in advance.
Your test page uses the Contact object as its standard controller, so in most cases you would want to specify a Contact record for the page/controller to operate on. You can use any existing Contact record in your org, or create a new one (specifically you'll want to grab the ID of the record) and then append the ID to the URL you're using like so: /apex/testpage?id=003xxxxxxxxxxxx. This will provide the page and controller a record to pass to the VF component.
I am having 2 problems in below code.

I'm working to customize liferay's Calendar portlet and have created a hook for this.
I want to show all the "Related Assets" associated with a Calendar Event directly in the list page itself where all the Events are displayed instead of the Event's detail view page.
Currently liferay shows the "Related Assets" only when we click on the Event to view the details of that Event.
Can anyone help me?
Environment: Liferay 6.1
Thanks a lot
Sabrina
I assume you already have liferay's source code and you know how to create a hook.
The JSPs you would be modifying would be in this path:
portal-web/docroot/html/portlet/calendar
So here are some steps to help you solve your query:
You need to modify the event_iterator.jspf: row.addText(event.getTitle(), rowURL);
You have to adjust the following code taken from view_event.jsp in event_iterator.jspf.
<%
AssetEntry layoutAssetEntry = AssetEntryLocalServiceUtil.getEntry(CalEvent.class.getName(), event.getEventId());
%>
<%-- <liferay-util:buffer> is a tag which stores all that is written inside
its body in a single variable string, in this case "relatedAssetsLinksBuffer"
--%>
<liferay-util:buffer var="relatedAssetsLinksBuffer">
<c:if test="<%= enableRelatedAssets %>">
<%=event.getTitle() %>
<div class="entry-links">
<liferay-ui:asset-links
assetEntryId="<%= layoutAssetEntry.getEntryId() %>"
/>
</div>
</c:if>
</liferay-util:buffer>
Now the line in step-1 becomes: row.addText(relatedAssetsLinksBuffer, rowURL);
I have not tried this but I think it would work or will atleast give you some help in solving your query.
Tip for Hooks (might be useful in future):
Liferay follows a convention in storing its JSPs, so for custom-jsps Hook (i.e. a hook created for modifying liferay's JSP) you just need to search for that particular JSP & modify it.
For Eg: You wanted to modify the first page of calendar portlet. So liferay portlet's first page is always view.jsp located in the folder with the same name as the portlet-name in this case "Calendar" and view.jsp will contain some tags like <%# include /> or <liferay-util:include /> which would include other files to show the content. So you can always start with a view.jsp and navigate ahead. By the way the names of the JSPs are also most of the time self-explanatory.
Hope this helps.
