are the same object, but in this instance, I am using Text for the
renderer and TextInput for the editor.
As mentioned before, these are not what I am really trying to set for
editor/renderer, but just set to there to simplify the problem as that
is the exact same error. So if we can figure out what the problem is
in this example, I should be able to translate that to my specific
custom renderer/editors.
But just to give it a shot, I tried with the imports (per Matt's idea)
with no luck, and I tried with the rendererIsEditor which made the
column uneditable (because I am not using TextInput).
>From the documentation, it looks like if rendererIsEditor is set, then
the itemEditor is ignored.
Any more ideas?
