tablelist bug

Hello,

I have configured a tablelist widget to have movable rows. The first time I use it, it works OK - I can move the rows. Anytime after that, I get the following error:



can't read "data(k0,0-indent)": no such element in array
can't read "data(k0,0-indent)": no such element in array
while executing
