Title: MVR020001 - warning in model validation of an activity diagram
Post by: mse on December 03, 2020, 11:30:43 pm: I have an Activity where I have a result pin of an action connected with an object flow to a parameter of the activity. When I do a model validation, I get the following error:

MVR020001 - warning (result (ActionPin)): result is missing required child element: Action

The result pin there, and it is connected, but what this missing required child element of type Action all about?

Post by: zednought on May 16, 2024, 06:54:18 pm: I realize the original post is more than three years old, but I'm also seeing this validation warning message in EA v15.2 and similar to the OP I don't understand what this message means.

Obviously an Action can have a child ActionPin, but not the other way around so the message makes no sense (to me at least).

Is this a bug or am I missing something?

Post by: mse on May 29, 2024, 12:57:06 am: Even the sample model in EAExample fails to validate. I tried the package User Interface Features > Properties UI > UML, and I got several warnings about the ActionPins.

I honestly don't know what kind of child element a pin can have. This could be a bug in EA. I know I had an issue reported once on EA regarding the ReadStructuralFeatureAction once before and I don't think it has been resolved either. It seems that Actions with pins have problems in EA unless someone can point out to us what we are doing wrong.
