I've lost the popup menu


With the portal admin user, when i click on the icon to choose in the popmenu an item (properties, modify, permission, …) I’ve a problem, redirect to the adresse javascript:void(0)
In the directory <server_name>\deploy\portal.war\ui\scripts I have the file PopupMenu.js

It sounds like there’s a javascript error being thrown.

Was there a solution to this problem?
