installed zimlet doesn't appear in panel
I've developed a zimlet which installs and works fine with zimbra collaboration suit. But when I deploy that zimlet on Zimbra Desktop 7.1.2. It says installation successful and ask me to enable the new zimlet. After clicking on Yes, it reloads the screen and the zimlet doesn't get display in zimlet panel. Its doesn't display in the list of zimlet under Preferences->Zimlets.
I deploy the zimlet in Zimbra Desktop 7.1.2 by going into Preferences->Zimlets and then browser the file.
There is no error inside the logs in ZDC.
Is this compatibility issue? If Yes, what should I do to make it compatible with ZDC?
