Hi. I’m starting to explore UI’s and reading about built-in options. I was following this guide on PopMenu and had some issues, it seems like some of the code may have changed since it was written, and maybe some bugs in the component.
In example 2, this codeblock should read “onOffToOn”
def offToOn(panelValue):
op('popMenu').Open(callback=onMenuChoice)
return
The Null DAT at the end seems to select one element lower in the menu than selected:
After creating the Table DAT as directed and wiring it up, there’s this persistent error in the lister element inside, that won’t go away:
If I change the Input Table option to Include All Rows, Column 0 is Items first, before wiring, the error doesn’t appear, but if it’s set to another option, the error appears and won’t go away even after changing the option.
