Make sure you are doing a setcontentlist to display the content when the category is selected. Also, sometimes you need to force a refresh of the screen, which I do by popping up a onelinedialog and then immediately closing it:
sub refresh() dialog=Createobject("roOneLineDialog") dialog.show() dialog.close() end sub
