I've added some new buttons to the Portal tab. These buttons are suppost to load pages similar to manifest.xml. In firebug i get the message: GET http://localhost:7070/zimbra/portals...l?v=1234567890 when i push one of the buttons. Problem is that the window doesn't refresh.
I know that this is a problem with the listener of this button, but i don't know how to solve this. I made that listener calls function getManifest(callback).

Can anyone help me please?
