Pls advise is it bug or problem when we call the method
It's a "bug" or the documentation needs to be updated I think. It only works for some reports so far unfortunately.
Technical background: I reckon it only works for reports returning dataTables maybe? Haven't had a look at the code yet.
in case you need to have a look on code, it is not a problem.
Not needed, we should be able to reproduce it. Thx though!
In general we have ineterst to make beta testing for new relase
