If you define an edit table a text field does not work.
The value entered is ignored.
See test case below.
Click the edit button below the table. Try and alter the value and save.
New value is ignore. Old value remains.
This will break many good Twiki apps. EditTablePlugin is one of the essential default plugins that must work. Urgent bug.
Update. I could make the exact same example work on my TWiki but not here. I noticed when I entered another Edit Table bug. Maybe it is because this is a form. See TestTopic22
If this only fails inside forms then the bug can be declassified to normal.
I can't see how it could ever work in forms. The plugin parses (!) the topic to find tables, and tables in forms don't have newlines (because form values are all on one line).
It seems to work ok in the topic body text.
Changing to enhancement because it would be good to have this support in forms.
