I'm taking over from Darren Atkinson on Apex/FOEX development, so this may be the first of many...
I have a page with a centre pane, and three Grids which are rendered as tabs. When the first tab is selected, and the report is run (Loading Grid Data is On Demand) I get the loading overlay with the Loading spinner until the report is rendered. However, when I select one of the other grid tabs (which are Load when Grid is Shown), I get no overlay or spinner and the page is just blank until the data renders. This is a slightly odd user experience!
Is there anything I've missed coding to get the over and spinner?
