I have not been able to get any additional information on this. The only response I have implies that this code interferes with another feature (add or remove columns), and was commented out for that reason. So it looks like we don't actually support the feature you are trying to use.
How can i manage dynamic report paging in the activity when i call a report? For example, in my activity i call Myreport that returns 3 pages.On these pages i have to perform some elaboration. In order to improve performance, i would like to load one page at the time in the clipboard and so looping for 3 times. How can I meet this requirement?
