PrimeFaces DataTable which is inside OverlayPanel stops working when OverlayPanel is used inside Dialog

Question

Here is my scenario. Room Object have ManyToOne relationship with Tax Object. There are two pages for Room, Create New and List All.

At Create New Page, there is Tax Field. I use OverlayPanel + DataTable + SelectEvent to assign Tax Object instead of using AutoComplete or SelectOneMenu. Everything works great at this page.

At List All Page, I use Pop-up Dialog to edit the desired record. OverlayPanel + DataTable not working anymore because OverlayPanel is inside the Dialog. SelectEvent still calls Tax Setter Method but value is null.

I use PrimeFaces 3.5 and looking for solutions that will work with PrimeFaces 3.5 only. Thanks for any help!

Answer 1

I think OverlayPanel (DataTable inside) is not compatible with Dialog. Using Dialog again instead of OverlayPanel solved the problem. Dialog inside Dialog works fine. I have to add appendToBody="true" attribute to child Dialog because UI is blocked. I use PrimeFaces 3.5 and works for me.
