Recently, I noticed a couple of issues reported saying that popup dialog is not getting displayed when used inside a table. There are some points you may need to take care while using <af:popup> inside <af:table>
- Please keep the definition of <af:popup> outside of the <af:table> .This would ensure table refresh( in other words DOM replacement for table during PPR) doesn't cause any harm to your popup component
- Please don't leave the table rows in an inconsistent state while you iterate through the table rows from the managed bean. Please see this post for more details.
