Holger,
Thank you for your quick response. I made the changes you suggested and
got this working!
Is there any documentation on all the different UI/SWA elements? I am able
to see general descriptions of the different elements under swa.Elements
and ui.ControlElement, but it is difficult to put these into a "big
picture" perspective.
Regards,
- Aubrey
