I am trying to use/modify the ‘opBrowser’ from the Palette, and when I want to drag and drop an operator from the tree list I get the following error in the textport:
Traceback (most recent call last):
File "/ui/dialogs/palette/palette/list/components/tree/table/drag", line 9
AttributeError: 'NoneType' object has no attribute 'numRows'
Traceback (most recent call last):

Oddly enough if I navigate to the line in the ui component causing the issue, and add an arbitrary
print(fullSource)
before line #9 the Drag and Drop works.
