ADF Popup - have to click button twice to close popup

Usecase:
User has adf popup with table. User launches popup and select a row from table and click "OK" button. But popup doesn't get closed. Popup is closed only on second click

An immediate="true" in the adf table definition could be the culprit. 

Sample table definition snippet
                         id="myid" var="myvar"
                        rowSelection="single"
                        immediate="true"                                             
                        contentDelivery="immediate">
                       
                                                .....
                       

Removing  immediate="true" will fix this issue.
