Cannot set multiplicity for a pin in an activity diagram

Based on the OMG specification a pin in an activity diagram is a multiplicity element, therefore it would be nice to be able to specify the multiplicity for a pin.

Dear Zsolt,

Thank you for your post. I’ve asked our development team to have a look at the OMG UML specification to see if we should support multiplicity for pins. When there is any news, I will let you know.

Best regards,

Hello Jick, thank you so much for the quick answer. Based on the OMG UML 2.5.1 standard

16.14.33 Pin [Abstract Class] Description
A Pin is an ObjectNode and MultiplicityElement that provides input values to an Action or accepts output values from an Action.

Hi Zsolt,

You are right. We will support it in the coming version. Thanks for letting us know. I will post again when it’s out.

Best regards,
