Add Dashlets to home page

I’m using Suitecrm 7.3
And have faced with problem.
When i add dashlets as admin i get java error:
current_dashlet_id = SUGAR.mySugar.currentDashlet.getAttribute(‘id’);

I really don’t know what happened

Ok, guys.
I found the reason of that problem!

On all my instanses was installed Asterisk Connector module. When i delete this module, all dashlets are creates normally.

Asterisk Connector is not work anymore.
