ArgumentOutOfRangeException when updating XamDiagram
posted

In my project I have an ObservableCollection of nodes and an ObservableCollection of associations. The data for the nodes/associations can be edited as well as added/removed in other tabs in the same window. If the user edits one node and returns to the diagram tab everything works perfectly. However, if multiple changes are made the result is "Index was out of range. Must be non-negative and less than the size of the collection."

I created an example app. It's crude and doesn't work entirely the same as my project, but I was able to repeat the issue.

In the example app, to replicate the issue: Click "Generate Diagram", then click on the "XDiagram" tab, click back to the "DefaultTab" and click "ChangeNode" more than once, once you click back to the "XDiagram" tab the app should crash with an ArgumentOutOfRangeException.

Note: The "ChangeNode" button removes a node then re-adds a node. If only done once before switching back to the "XDiagram" tab, everything works successfully. Also, the app crashes before the OnLoad function for the "XDiagram" tab is called.

Attached is both the stack-trace and the example app.

    Hello,
    Thank you for contacting Infragistics. I've reproduced and isolated the behavior and I've logged a development issue (# 260719) with our developers to investigate this further and opened a private case ( CAS-200114-M0N0N5 ) to provide you with further updates regarding our investigation. You may visit the case from the support activities section > In development tab from your account.
    Let me know if you have any questions.
