I have a p:dataTable and the selected value is throwing null pointer when Im tring to get it,this situation is after put the datatable inside a modal p:dialog, but if remove the modal atribute works fine. PD:the modal p:dialog was behid the overlay like this question
Primefaces - AjaxStatus - Dialog is behind the overlay
the answer is not working for me, because Im using primefaces 5.1, so I have to use appendTo="@(body)"
I don´t know if that is important for my problem.
Resume: the null pointer exist if the p:dialog is modal.
Here is my code
