    I have a jump list with groups defined inside a pivot control. With the exception of the
    GroupPickerItemTap event, all properties are bound.

    I have my group descriptors and sort descriptors set upon in my viewmodels
    constructor. The control works properly when I hit the page for the first
    time, but when going back to the page, I'm getting the error
    "Descriptor is already added to another collection view." I'm using mvvm
    lite's view model locator so the viewmodel at this point is not a new
    instance. I am trying to stay out of the codebehind as much as possible
    with this project. Any help would be greatly appreciated.

    Thanks,
    Mike

    Hi Mike,

    This is a known issue with RadJumpList. When using a collection of data descriptors in a static View Model as a source this issue occurs the second time a JumpList control tries to bind to it.

    A fix will be available in our next official release.

    Let us know in case this issue is a show stopper for you so that we can prepare an Internal Build containing the fix.

    If it's not too much trouble,  a new build would be great.  It would be a lot of work on my end to fix it temporarily.

    Hi,

    I also noticed the "owner" field which makes it impossible to bind Descriptors to more than one JumpList.
    Deyan could you please write here when a fix is available - so I get informed about this "fix".

    Thank you
    Manfred

    Hello Mike,

    Thanks for writing back.

    The Owner field is exactly the cause for this behavior. We have already addressed the case so an Internal Build will be available very soon for you to download. I will make sure to let you know here.

    All the best,

    I doubt this IB is to blame, I think i'm just having some bad luck.  Anyways, I updated my referenced dlls and now my app won't even hit the constructor on the app.xaml.cs page.....  I may give up for the night.

    I reverted my changes to the old builds and verified I had a working application. 

    I deleted all references to the telerik dlls, deleted the local copy I have in a folder in my project for source control.  Added the new ones, and the application will not run.  I'm not really sure what I can be doing wrong. I'm not getting any errors which is the really bad part. The app starts and I'm immediately back at the start screen on the emulator.

    Hello Mike,

    This sounds like a weird behavior.

    The IB contains a fix for the Owner issue in RadJumpList, i.e. we have removed this Owner dependency which made it impossible to use a Data Descriptor in multiple RadJumpList instances. Is there a possibility that you send us your project so that we can make sure that the references to the IB are correctly updated and that there are no other issues that might be breaking your app?

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

    Thanks for your time.

    Sure thing.  I'll try to do that later today.  I'll include both versions if I'm allowed to upload that much.  Thanks
