Strange TreeTable parse behavior

I think the screenshots would make the issue clear:


tt the object of my Treetable. As you can see, it has 4 columns, with the IDs being ‘colfilter’, ‘C’, ‘T1’, ‘T1C’.

Then I parsed a simple json with the same ids as keys. But as you can see in the next screenshot, the last column picks up the value from the ‘T1’ key for some reason.


I’m completely lost on this issue. Any help?

EDIT: It was a problem in my custom template function. Please close/delete. Thanks…
