Hi,
I'm running into some issue from time to time, but now it occurs each time I try to populate on demand.
The error message is:
Error when performing server callback:
Object reference not set to an instance of an object.120|/ followed by a combination of characters, digits and special characters like + and /.
If it appears sometimes, I just need to give the tree some more time to load and it works fine with exactly the same code. Now, it happens no matter how much time I wait before clicking to populate. I'm using version 4.3.1.140
Do you have a hint what to look for?
BR,
