error on saving the whiteboard as a file #1082

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
some problems in saving the whiteboard as a file:

(1)
when I click the save button in the save popup in the whiteboard, none
of file can be saved.
Instead of that,  the error as below occurs.
 "The Connection to the Server is lost. You need to reload the
Application or/and check your Network"

...and then the app crushes.

(2)
when I click "Download as png" link in the popup, the file can be
saved, but drawed lines are shown  but not correctly.
