I'm new in this community, but I really need help!
I'm programming a application which gonna run in Desktop, with Java, and online, with Java Web, using Hibernate 4.3, without JPA, and Primefaces 8.2.
My issue is, I have a page with a dataTable, this dataTable contains a button on each register to open a dialog with more information of this register.
Inside this dialog i have another dataTable with another button inside each register.
Here I have two issues.

First, when user clicks on the button in the first dialog, the second dialog appears but, it just ignore the ActionListener.

Second, on the first dialog, when user clicks to go to other page of dataTable, or just increase the number of rows, the data disappear! If you close and reopen the dialog, it open in the page you clicked before and the data will be there.

I'll post the principal code of the problem, the github link and a video to make it easy to figure out the problem.
