Hello,
Your method generateConnectorDeclarationPortParameters() calls
getPortParameters() and getPortParameters() calls
generateConnectorDeclarationPortParameters() so it looks like a loop
that explain why Eclipse is not responding.
However, I do not think that you need java code to do this. In the Node
creation tool that creates your ConnectorDeclaration element, you can
ask a "for" operation with expression "connectorType.getPorts().size()".
Inside this "for" operation you add a CreateInstance operation typed
PortDeclarationReferenceParameter with referenceName "portParameters".
Regards,
Steve

Hello,
thank you for the answer. But, in fact there is another problem. In the time when I will create an instance of the ConnectorDeclaration the type is not set. So after creating an instance, in the Properties window I set the type of the ConnectorDeclaration. I implemented your solution, but because of this issue the Border Nodes are not appearing. I tried to put a fix number in the Expression in the for loop (let's say 1), and it worked. So, I think the problem is how to do the same, but after seting the type in the Properties window.
