Cuba Studio 7.0 breaks on setting rows datasource in table

Support
#1

At least I think that’s what’s happening. To fix another problem, I removed all the grid layouts from a screen, and got this error for one of the tables:

Might be related to setting the rows element on the table, because the editor loaded when I removed, but then would not let me set it. While I was trying to set it though, the editor destroyed all the other data source settings by removing the ```id```` attributes from the XML. Not a nice thing to do.

Hi.
If it is possible, could you share the xml file of your screen to help us investigate the problem?

I can certainly do that:
