Trying to do something which is very simple but am getting strange results.
I have an image stored as an attachment which I want to display in a VF Page.
If I do this it works fine
<apex:image url="{!URLFOR($Action.Attachment.Download,'00PR0000008Q3YmMAK')}"/>
However that was for testing purposes that I hardcoded the id. If I try reference the Id in the object then it fails. Even though the value contained in the object is exactly the same as above.
<apex:image url="{!URLFOR($Action.Attachment.Download,model.PreviewImageAttachId)}"/>
When I load the page I get an error in URLFOR param!!!
I thought my problem was because model.PreviewImageAttachId was a String and not an Id so I created a wrapper to return it as an Id - same error.
I then decided Salesforce must have some strange requirement that you can only pass in the REAL object so I did that and passed in model.Attach.Id and it still fails!!
Please can someone explain this to me and more importantly suggest a solution??!?
Once again if I output to the page
{!model.PreviewImageAttachId} i get 00PR0000008Q3YmMAK
So I just cant explain this!
Thanks!
My bad...
Was using apex:repeat and turns out SOME of the id values were null.
Hence the error

Umbraco uses angularJS as based library and backoffice totally developed on it. The reason telling first is to tell that I have a field on which URL regular expression applied. If someone entered invalid url like below image
it shows error as need.
But if a user try to remove whole text by selecting it and removing at once. It still keep appearing the error like this
However, if a user erase text one by one like this
then the validation error removed and user need to click on button to see error again.
I would to know how screen 3 state can be achievable when user remove all text together? Its really annoying behavior for a user to remove text character one by one to refresh the state of the field. Screen 3 state should be applied on screen 2.
Can anybody tell me how it can fix or achievable? Right now, it seems like a default behavior.
Looking forward to hear from you guys. Suggestions will be much appreciatable.

I've looked into this issue. This seems to be a product bug.
When you remove whole text at once, newValue is an empty string and the code responsible for resetting error messages doesn't run. If you have access to the umbraco code, you can easily fix it by removing highlighted check:
I'm trying to get data from a Highchart, but I only have a "None" value.
The chart needs a password to be accessed, but I have the same problem with the chart on this page.
Using the browser's DevTools I can get the y value from highchart using:
Highcharts.charts[0].series[0].data[0].y
Thus, combining this code with a loop structure I can have all the y values.
The problem is when I try to use Selenium to webscraping those values. I'm using the code below
page.execute_script('Highcharts.charts[0].series[0].data[0].y')
The answer I expect is 2 (as in DevTools), but instead I'm getting "None" as answer.
I already tried to use Beautifulsoup to retrieve the y value from the <path> tag, but it doesn't meet the expected value.
The HTML source seems to be complex (I'm not expert in these area). The full xpath of the <svg> is:
/html/body/form/div[3]/div[2]/div[2]/section/div/div/div[2]/div/section/div/div/div/div[2]/div[2]/div[1]/div[2]/div/div/svg
Also, I can't find any <iframe>, which could be avoiding me from accessing the graph.
Does anyone knows what I'm doing wrong? (I'm beginner in this area, so let me know if any further information is necessary)
After a long time stuck in it, I figured out how to solve this problem.
My mistake is that I was sending to my browser, via selenium, the js script below to be executed.
page.execute_script('Highcharts.charts[0].series[0].data[0].y')
This code is working perfectly but it doesn't return to me any value. So, in order to have the y value (that is what I need), I just need to use a "return" in the previously code. The final code is
page.execute_script('return Highcharts.charts[0].series[0].data[0].y')
Issue with JSON LD CODE
To start with I am trying to use this code in weebly, buy using embed code option and then I click on the edit custom HTML and enter this code. However, after entering this nothing shows up as in the recipe is not shown on the page and a blank page is shown.
this code is picked on schema.org, for recipes.
Could anyone please help me out in what exactly went wrong. I really appreciate your assistance. FYI- I am new to this. I am trying to set up my own food website and and wanted to schema to for SEO improvement. Any other suggestions are welcome. Thanks in advance.
Please refer this link for the JSON-LD CODE. IT WILL BE AT THE END OF THE PAGE. https://schema.org/Recipe
When you add a JSON-LD block in the HTML, it doesn’t change anything visibly on the page. The script element is hidden by default in all browsers, and you typically want to keep it like that (users typically have no interest in your JSON-LD code).
To check if adding the JSON-LD worked correctly, open the page in a browser and check the source code of the page. You should see the script element with your JSON-LD.
You have to add the content (that should be visible to your users) regularly with HTML. The JSON-LD exists next to your content (duplicating the data like name, photo URL etc.), it doesn’t replace your content.
{
"$id":"-KMVCUSAsz92c0Hp296i",
"$priority":null,
"aQuestion":"what is your favorite color",
"option1":{"option":"red","vote":1},
"option2":{"option":"blue","vote":2},
"option3":{"option":"green","vote":0},
"option4":{"option":"yellow","vote":0}
}
So using dot notation to access this object from Firebase, using vm.data.$id and vm.data.$priority returns the correct value. However using vm.data.aQuestion or vm.data.option1 yields undefined. I've looked at several posts, however none have fixed this issue for me. Is there something simple I'm not understanding?
Okay, I think I may have figured it out. I was luckily able to find this post shortly after reading Surjeet's about something making my field null or empty.
Cannot access Firebase object attributes. Value displayed as undefined ANGULARFIRE
Because Firebase values are loaded asynchronously, the value did not load. after using vm.data.$loaded().then was I able to retrieve through dot notation. Not sure if this is the best way, but it works. Thanks everyone for your help.
Also, if anyone that reads this has a better way to go about this issue, please let me know. Thanks!
Try to see have you did something in your code which is making your object field null.
If not then,
Try this one vm.data['aQuestion']
I do a standard pattern in my application - a link to /controller/delete/object_id, then a post form to "confirm", a check if $this->request->is('post') and if true - the controller deletes the object from database.
What is weird is that for a single, particular object_id, my browser (Firefox) forces the form to be a GET one. With any other object_id everything is ok, but with this particular one, despite all declarations within form tag and etc. brower generates a GET request.
Do you have any clue what this might be?! I even tried to use brower's private mode, because I thought it can be some garbage in browser cache, but the bug is still here.
I managed to bypass this problem:
define a specific action in form->create, pointing to your controller' method
add a hidden field with object_id
add some additional code in the controller method to get object_id from $this->request->data, because a hidden post field is not passed as an argument to method, as it is with GET method.
This way, to some unknown reason, it just works. Anyway, I still feel I'm doing something wrong. It's not as "clean" as I would expect.
