JumpList odd behavior with images

[Derek]

I have a JumpList bound to a List of Items.  My template is simple, each item has a image path and some text.  The template is simple, a Image control with a TextBlock.  Those are bound to the properties on item.  Everything works as expected except random images that exist in IsolatedStorage won't display.

The odd thing is, an image that exists in IsolatedStorage and isn't displaying, will display if I scroll down a bit and then jump back to the header group.  So if an image in the B's isn't displaying, I can scroll down to the D's, tap the group selector, jump back to the B's and the image displays.  

I've checked several things including the converter I'm using that returns the Image source.  I've tried setting IsAsyncBalanceEnabled to both true and false but that doesn't change anything.  If you can't think of anything off hand that might cause this I can create an example.

Thanks.

Hello Derek,

Thanks for writing and for reporting this issue.

We are currently not aware of similar issues but we are willing to investigate the case. We therfore would like to kindly ask you to prepare a sample project that reproduces the scenario and send it to us for further investigation.

Please note that you will have to open a new support ticket in order to be able to attach your project.

Thanks for your time.

My scenario is this.  I'm using MVVM (Caliburn Micro), I bind the RadJumpList to a List.  One of the properties of an item in the List has an ImageId.  I bind the Image source in the ItemTemplate to ImageId and use a converter to resolve the local image.  All of the images exist in IsolatedStorage in /Shared/Media.

It's easy for me to swap out what is being bound to so some quick testing:

RadJumpList (random missing images)
RadDataBoundListBox (random missing images)
ListBox (no missing images)
LongListSelector (no missing images)

I thought it was a problem in my converter but after the above tests I'm sure it's not.  If I have time I'll try and put a sample together.

I've managed to narrow this down to: If I don't set the jumpLists GroupDescriptors the problem doesn't occur.  When I do set them, it happens.

[Derek]

I created a sample and attached it to a ticket.  Thanks.

The peroblem went away when I upgraded to the latest version at the time.

Hi Christian,

Could you please try explicitly setting a size to the image element within your Data Template and let me know if this fixes the issue for you?

If not, could you please send us a demo project reproducing the scenario so that we can take a look and see how we could help you? You can do that in the support ticket you have opened regarding the same topic.

Thanks for your time.
