Also i can reproduce the strange 'when is only one row there is no data' error in datagrid field. strange stuff

That's because of the hidden counter-field the widget depends on. I though it to be an independent issue from this relation stuff.

Yeah probably this is an independent issue.
Somehow i can't seem to reproduce this every time, will futher look in to this
