Error on fast re-layout

[Elad]

Hi,

I have a listview with filters, filter click is changing the listview items. (similar to ebay app)
if the user filter and wait until layout is completing there is no problem.

when the user filter twice fast (without waiting for the previous filter to apply) this exception is thrown:

Java.Lang.IllegalStateException has been thrown
Added View has RecyclerView as parent but view is not a real child. Unfiltered index:0

this came from RadListView.java:538 at com.telerik.widget.list.RadListView.onLayout(RadListView.java:538)

I'm using forms, but this is occur only in android (ios is working)

any chance to fix this in the next release?

Thank You

 

[Elad]

please close this issue.

there were a bug at our side.

What was the bug?
Whe have the similar issue with a RadListView and a ListViewLoadOnDemandCollection

[Marek]

I'm experiencing very similar issue on Android and iOS. From time to time the app just crashes on native part.

 

Here is the Android stack:

and here is:

 

*** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'the collection view's data source did not return a valid cell from -collectionView:cellForItemAtIndexPath: for index path <NSIndexPath: 0xc000000000c00016> {length = 2, path = 0 - 6}'

 

Crashes are much more likely to happen on iOS

[Marek]

I managed to get some more detailed info for iOS:

 

Application Specific Information:

Hi Marek,

We are not aware of such an issue with RadListView, that's why I'd ask you to provide more details on the exact setup you have.  If you could send us the definition of the ListView as well as steps to reproduce the exception, that would be of great help.

I'm looking forward to your reply.

Hi Dinesh,

I would like to ask you to provide details on the exact setup you have. Could you please send us the definition of the RadListView and the steps to reproduce the exception. In this case we could research it further.

Looking forward to your reply.
