Hi,

I need to apply a custom field (free text as string type) on the Property object of my model.

I read the article : https://www.eclipse.org/modeling/mdt/uml2/docs/articles/Customizing_UML2_Which_Technique_is_Right_For_You/article.html

So the right technique to use is "Lightweight extension".

I tried to modify the Property object in the Profile applied to the model but it reports a violation error.

How to extend the Property object in the metamodel ?

Thank you, José

Hi

You should ask UML questions on the UML2 newsgroup/forum.

Your snapshot is far from clear as to what you are doing where. It looks as if you attempting to modify the Property definition in the UML metamodel rather than a Property instance in your UML model. I suggest you follow some simpler tutorials so that you understand the difference.

It is also unclear why a normal Property with a String type needs customization for you.

Regards

Hi,

I need to add a custom meta field so i can modify it upon each Property in the model.

I'm expecting to see it in the properties view of the property inside Eclipe (IBM Ratrional Software Architect), see screenshot.

Actually it is meta information such like alias, type, qualifier, etc...

Thank you

Yes, better to ask on the UML2 forum: https://www.eclipse.org/forums/index.php/f/117/
