server error when using message blocks #44

Closed afgym-baeu closed 7 years ago

afgym-baeu commented 7 years ago

The lab (lab.open-roberta.org, release 2.2.5, ev3dev) shows a "Attention - Server error" popup when starting a program that contains a message block, even a simple wait for connection. The gui switches to a new project and all unsaved programming is lost.

This is the server's error log:

2017-06-13 21:21:07,526 [qtp28241199-15] session-id=[1] user-id=[-1] robot-name=[ev3dev] ERROR d.f.i.r.j.r.all.ClientProgram - Exception. Error ticket: E-1 java.lang.ClassCastException: de.fhg.iais.roberta.syntax.check.hardware.RobotProgramCheckVisitor cannot be cast to de.fhg.iais.roberta.visitor.actor.AstActorCommunicationVisitor at de.fhg.iais.roberta.syntax.action.communication.BluetoothWaitForConnectionAction.accept(BluetoothWaitForConnectionAction.java:40) ~[OpenRobertaRobot-2.2.5-SNAPSHOT.jar:na]

I'm wondering if this is ev3dev specific or should be reported as an issue to the openrobertalab repository!?

Just discovered same exception when using leJOS EV3.

Could you please file server side bug on the robertalab? This saves me quite a bit of time copying them over.

Done. It's url
