Lock Screen does NOT work!

[Bob Sneidar]

Oooohkaaaay...

So the problem is not calling selectionChanged while another selectionChanged is running. The problem is setting the dgData (or dgText I will assume) while a selectionChanged handler is running. I remember I tracked that down before this. Setting the dgData is obviously triggering selectionChanged from within the datagrid library. 

Soooo... I AM calling this a bug!!! I will try to put together a recipe for this and submit it.

I have code in my selectionChanged handlers in the datagrids that update the card objects; fields buttons etc. It's convenient for me therefore when I change the hilited line by script to simply send selectionChanged to the appropriate datagrid. This however has uncovered an anomaly (I don't say bug) where an endless recursion can occur in the datagrid library if selectionChanged gets called again while the first is still executing.
