I do not know if this is the default behavior but it is frustrating me. I have some pages that use the same pageTemplate. Within page template I have a MenuItem that is used to display an information popup. The problem is that whenever the popup is opened, whenever I click the menuItem, the page where I am located gets refreshed! I have removed the partial submit from the MenuItem and nothing changed. Is there a way to make the page not to refresh in this case?
I finally found the solution and the problem. I was calling the popup programatically, and for some strange reason this was refreshing the iterator on the page. I made the popup calling through "showPopupBehavior" operation and everything got resolved.
