I'm using dynarch menu in my web application. My web page is having 6 iframes and the context menu will appear on right click of each of those iframes. This is working fine. Here is my problem. I'm opening the same web page as a modal dialog. From this page, when I try to navigate to a different page which is also having iframes & context menus, I'm getting the following javascript error " 'length' is null or not an object ". Why this is happening for modal dialog? Is there a way to solve this problem? Please help.
