Title: Use of EA.Transition VS EA.Connector
Post by: avantol13 on June 20, 2014, 01:06:33 am

I'm trying to connect two states together with a transition in a C# addin. I can create the states and the "Transition" but don't know how to set the destination of the transition.

Alternatively, I've attempted using EA.Connector and setting the TransitionEvent/TransitionAction/TransitionGuard values. When using EA.Connector, it connects the 2 states but with a "dependancy"  not a "transition".

Any help would be greatly appreciated. Just getting to know the software and it's capabilities so forgive me.

Regards,
Alex

When you create the Connector supply "Transition" as the 2nd parameter.

I tried that and when I go into EA and look at the connection, it's a dashed line and when right clicked it says "Dependancy Properties" instead of the desired "Transition Properties".

Here's a snippet of my code. states is a List<EA.Element>

connector = (EA.Connector)states[0].Connectors.AddNew("TRANSITION_EVENT_ONE", "Transition"); //source state
            connector.SupplierID = states[1].ElementID; //destination state
            if (!connector.Update()) //check for error
            {
                Console.WriteLine(connector.GetLastError());
            }
            states[0].Connectors.Refresh();
            connector.TransitionEvent = "TRANSITION_EVENT_ONE";
            connector.Constraints.AddNew("TRANSITION_EVENT_ONE", "Signal");
            connector.Update();

On another note, the constraints attempt above doesn't appear to work either. :(

It appears that you have to create a "StateFlow" connector. That will do the job. I just tried that.

Regarding the constraints: for me the Update also fails. You should send a bug report to Sparx.

"StateFlow" worked! Thank you so much.. I would've spent a bunch more time sifting through the help topics to figure this one out. I must've missed "StateFlow" the first time checking the different types of connectors.

Thanks,
Alex

Actually I created the connector in an empty repository and ran a SQL

Code: [Select]

SELECT * FROM t_connectorThat gave the immediate answer.
