I noticed that the “dat out” from the popMenu operator in the palette browser returns the wrong name of the selection.
It is a simple fix it appears - I did it by locating the (popMenu/selectedRowSelect) within the component and removing the +1 from the pars “Start Row Index” and “End Row Index.”
While playing with the popMenu I noticed that reducing the number of items on the list to 1 entry, breaks the widget also in that it always returns a selection of “-2” on the out null… not sure my intial suggestion that it is a simple fix is entirely accurate.
