Should be a simple: Grid rows are not displayed

[Tomeo]

Hi folks,

I'm trying to implement pagination grid into panel, but unfortunatelly grid rows are not displaying (please see attached picture). Pagination works fine.

I know, this should be simple, and I'm missing just something small, but I can't spot it at the moment 8-|

What i just see, your grid has no height defined. Why has the ContentPanel you put the grid into a FormLayout? Try to give it a FitLayout.
