hi evrybody;
i have this metamodel of statechart diagram(StateChartDiagram.png)i want to apply an ocl constraint to the InitialState classe in especially.
i I wrote in statchert.ecor this code:
invariant OneInitialState:ContentIn.state->size()=1;

but this piece of code is applied on all the states, i cant draw in the model conforme in this metamodel unless one state.

My question is:
how can i apply this constraint on the InitialState class only.
thnks for the hep

do you have a bit more extended description of what you did? Which plugins did you use to specify the OCL on your diagram? A bit more expressive excerpt of the OCL definition together with on which model elements you specified them. Everthying would be helpful.
