Major Description
After creating a few users in Administration->Users, while attempting to delete one of them gave:
“internal error
Return to Home page”.
From MySQL command line, we deleted this user entry in database. Then, everything worked fine. We created this user entry again. But later, the same error randomly appeared while just CLICKING this particular user (and not others). Again, we deleted this new user entry in the database. Then, everything worked fine again.
In sum, the error regarding deletion of user appears randomly. We used this tedious workaround to delete the entry of that specific user in the mysql database and recreate the user entry. We are using mysql-JDBC-5.1.34. and MySQL 5.1.37.
Below is the stacktrace. The cause of the error is perhaps at this line in the log:
“Unexpected error occurred org.apache.wicket.WicketRuntimeException: Method onRequest of interface org.apache.wicket.behavior.IBehaviorListener targeted at org.apache.openmeetings.web.admin.users.UsersPanel$2$1@31a1d07e on component [Item [Component id = 5]] threw an exception at org.apache.wicket.RequestListenerInterface.internalInvoke(RequestListenerInterface.java:268) ~[wicket-core-jar-6.20.0.jar:6.20.0]”
