Adding attributes to a class via modeling workbench [message #1850975]

Hello,

I have a class in my metamodel called entity and I don't want to give default attributes to this class, instead I want to let people who use this workbench add whatever attribute they want to their "entity" object. How can I make this happen? I couldn't find a element edition tool that lets modelers do this.

Thank you for your answers.

Hello,

If I understood corectly, in your metamodel, you just need a containment reference (0..*) on Entity typed Attribute. Attribute would be an EClass with a "name" string attribute and probably a type string attribute (and whatever else you would want to specify an Attribute). In your odesign, you can have a container mapping for the entity. Inside it, you add a node mapping for the Attribute. Then, in the tool section, you will just need a container creation tool for the Entity and a node creation tool for the Attribute elements.

Best regards,
Steve

Hello,

I was able to make a node creation tool for the EAttribute type, but when I try to select the EType of that node, I can only see the types that are defined in my metamodel.I attached an image that explains it.

However, I don't want to see only these types, I want to see all the types that ecore provides, such as String, Long, BigDecimal etc.

How can I make this happen too? Thanks for the answer.
