Transformed Data View doesn't work

[thorsten-reitz]

Occasionally, I get the following stack trace when trying to open the Transformed Data View, which prevents using it:

The issue goes away when restarting hale studio.

@thorsten-reitz Did you notice anything systematic about when this happens (e.g. w/ specific projects or w/ a specific workflow) that would give us a hint how to reproduce the problem?

[thorsten-reitz]

Unfortunately I don't have a clear repro case. I wonder whether it is a timing issue, i.e. clicking something while the transformed data view transformation is still running. Once it occurs, it is not possible to open up the transformeddata view anymore.

[JohannaOtt]

Still occurring in 4.0.0 release. Unfortunately, still no clear reproduction case.

[thorsten-reitz]

Do you mean the 4.1.0 release candidate?

[JohannaOtt]

No, I mean the 4.0.0 release.
