Hello,
I currently try to extract and customize the whiteboard and use it
through the web service. When using the draw action I get the
following error on the server side. Different users on the same board
can not see each others actions and drawings are lost after reentering
the board.
[ERROR] [pool-4-thread-16] org.openmeetings.app.remote.Application -
[sendVars]
The correct output should be something like this, I guess:
[DEBUG] [pool-4-thread-16] org.openmeetings.app.remote.Application -
*..* sendVars room_id: 3 rcl.getRoom_id 3 is euqal? true
Any idea what goes wrong there?
Thanks and cheers,
Cyril
PS: here the complete red5 output:
