28277 3/12/12 12:31 PM 1 mircea.toma ICE-7781 Changed PanelPopupRenderer to use JavascriptContext.addJavascriptCall method to send the JS code for auto-centering instead rendering the JS code in the component's markup. Using this approach we make sure the auto-centering is sent along every update of the popup.
