Camila Feliciano asked on Okt 20, 2016:

I was running a simulation with signals and got another error. Can you help me again?

Re: NullPointerException in SignalsModule

I guess you forgot the line scenario.addScenarioElement(...) in your controler.

Or, if you have the line there, you do not use the scenario where you add the element: Do you create your controler by new Controler(scenario) as it is shown e.g. in RunSignalSystemsExample?

Please let me know if it works.

Dear Camila,

could it be that you define a signal system ID in your signal system file for which you do not give a signal control in your signal control file?

Can you please attach (per drag and drop) your signal input files if this does not solve the problem?

Cheers,
Theresa
