I am creating a flextable and adding cells in it dynamically. Flextable is inside scrollpanel but scrollbars never come vertically. They always come horizontally/
<g:ScrollPanel ui:field='toppanel'>
</g:ScrollPanel>
Flextable is added in this Scrollpanel dynamically as toppanel.add(stutable);
I think you must set the height of your flextable.
