I have a Spark TitleWindow popup with Form,
which among other widgets includes DataGroup (one of FormItem's)
with custom ItemRenderer (where I put rows of data as per dataProvider contents - custom component).
So user should Add or Remove a row of data on button click.
Adding/Removing row works, but the popup size remains the same,
so after adding more than 1 row it starting covering buttons underneath,
then row goes out of popup.
Is there a way to adjust popup size (make popup listen to number of rows)
or at least put these DataGroup rows into some vertical scroller?
(so far neither option worked for me).
