not found how to get the FilterBar being rendered with the filter fields, when added to the grid. Each column is set with size (not flex). To get working the showHide() button must clicked twice! It gives the idea, that the component itself is about being rendered, but unfortunately not.

Another issue I have, how can I set one of the filter columns a default value? Or this set a column filter to mandatory, and load another filter's combo?

Trying to add to ext 4 project.

thank for any hint,
