We are having a winforms add-on as a visualization in SpotFire. In the program we manullay set Tags using the below code

Tagcolumn = table.Columns["tags"].As());

Tagcolumn.Tag("tag", rowSelection);

After the above code is performed and when the UI refreshes to show the new tag,SpotFire is throwing below unhandled exception randomly (i.e) it does not always happens, I get 2 out of 5 times this exception.

"System.InvalidOperationException was unhandled

Message: An unhandled exception of type 'System.InvalidOperationException' occurred in Spotfire.Dxp.Application.dll

Additional information: Attempt to get snapshot info of a node state of type 'DisposedDocumentNodeState'.



This error happens consistently If I have opened scatter plot with kmeans and line similarity applied on the plot.

Does anybody have idea why this happens and how to handle this error in the code.
