Dialog not updating after populating model in action method

Question

I am using a primefaces dialog box. I have a list of items, and whenever I choose an item, I want the dialog box to display that item name. However, this is not happening. Rat

Answer 1

You forgot to update the dialog before opening.

<p:commandButton ... update="dialogId" />

I also suggest to use oncomplete instead of onclick to open the dialog.
