Create Sequence Connector Programmatically

[Tehila1]

I would like to create programmatically a self-connector, using C#.

This is how I do it in case of an Association connector:

Code: [Select]

//Create new Association connector
object connectorObject = selElement.Connectors.AddNew("NewConnector", "Association");
EA.Connector connector = connectorObject as EA.Connector;
if (connector != null)
  {
    //self-connector
    connector.SupplierID = selElement.ElementID;
    connector.ClientID = selElement.ElementID;

    connector.Update();
    selElement.Update();
    selDiagram.Update();
  }

But when I try to create a sequence connector I get the following error:

Code: [Select]

object connectorObject = selElement.Connectors.AddNew("NewConnector", "Sequence");
Error: Sequence is not legal for Class -> Class.

Any ideas?

The message is correct. In a sequence diagram you need to have instances, not classes.

You're right.

I dragged the classes as lifelines to the sequence diagram.
Now I get the following error: "Sequence is not legal for Object to Object".

lol - I had no issue creating a sequence with this Perl snippet:

Code: [Select]

my $e = $rep->GetTreeSelectedObject();
my $con = $e->Connectors->AddNew("test", "Sequence");
$con->{SupplierID} = $e->ElementID;
$con->Update();
The selected element was a simple lifeline. Sequence connectors are meant to work with lifelines in SDs. I was able to create a sequence connector for an object but it will not show in the class diagram.

Thanks for the test.

What version of EA do you use? I have the full 12. May this is the reason?
And a rude question: Why didn't you try the C# code?

There is an issue with creating sequence messages in automation. I believe a fix will be in the next release. Until then, try turning off syntax checking: Tools > Options > Links > Strict Connector Syntax.

I also tested with V12.

I simply don't use Cxx because Perl is by far more easy to create such simple code snippets. I only installed a Cpp compiler (for the first time on a Windoze machine) for a test where Perl could not work (something with add-ins). I'd rather use Ruby but that did not really make it except for Rails. And Perl is one of the few languages which run the same on Mac, Linux and Windoze. (Yes, Cpp too, but I regularly have to vomit over my keyboard when I have to deal with DLLs and all that windoze stuff).

Thank you all!
Deselecting the checkbox, make it work, indeed.
What are the consequences of deselecting it?

It will not complain :-)

In other words: you can create non-comformant UML. So Yoda speak you can, UML you use.
