Hi All
I have been going through the classes we have developed over the last few years and sharing back with the community some of them that I think will be useful to others. These components have been tested extensively in ext-3.2.1.
Here is: Ext.ux.ShowHideLoadingMask
A singleton used to show or hide the loading mask manually or automatically while requests are still outstanding. Remoting features are tested using ext direct with the direct provider stored in a global javascript variables called directProvider.
