Newbie C Developer Model and code gen issues

[KTPIntamac]

I began using Rhapsody earlier this year for a few Java projects, the current project is using C and is to model a hub and a few sensors. So I have modelled these as separate classes each with its own statechart, so i have a class called Hub, and two others called fire sensor and water sensor which both have associations with the hub at both ends. I wish to generate events and have done using RiCGEN(me, evEvent()) and that works fine within the same statechart/class. The problem I am having is when I want to generate an event in one class say the hub from one of the sensors, ive tried RiCGEN(me->itsHub, evEvent()); but this didnt work but compiled fine. I have now got it so the event in the statechart in a sensor calls a operation in the hub class, printing to screen from this operation works fine but RiCGEN(me, evEvent()) again doesnt work. Also if I try and pass an argument to this operation then assign it to an attribute (me->Attr = argument) I get a runtime error STATUS_ACCESS_VIOLATION.

Any Ideas as to what I have done wrong?, I apologise if i'm missing something obvious, I am a newbie

What you are saying makes sense. Perhaps you've forgotten to instantiate the classes as objects, the relations as links or select a class for main to create. It depends on how you are 'building'.

I've attached a model of what I think you've described. It was done in 7.6.
