Hi, again!! I have a new question now. I am using the STATE_SAVING_METHOD = 'client' and when I try to use the dataTable's preserveRows property, appears a error "Error while saving state in 'client' of type RowData". My real problem is that I want to work with the dataModel adding and deleting lines in a table. In the first time works, but in the next, my dataModel variable becames null and appears a NullPointerException.
Any ideas? Thanks Guedes
