Extended Model needs class/type instance of the referenced Base Model [message #885005]

Hello,

I'm new in the topic of the Eclipse Modeling Framework. Actually I have a BaseModel.ecore. In another EMF Project, I have a ExtendingModel.ecore which references BaseModel.ecore. The ExtendingModel.ecore needs an instance of a type in BaseModel.ecore.

Starting the editor for the ExtendingModel.ecore shows only the modeling elements for the ExtendingModel.ecore but not the elements for BaseModel.ecore.

This is the current problem I have. I need an instance of a Class/Type in BaseModel.ecore for my ExtendingModel.ecore. How do I achieve this? Is there any good practice? Did I understand something wrong?

I appreciate any help.

Show's it where? The properties view or the initial wizard?

Do you have containment references to them or non-containment
references? In the former case, I'd expect you to be able to create a
new child of the correct type. In the later case, you can use Load
Resource... in the context menu to open a resource that contains the
types of instances you need; those objects will be available in the
properties view

Hi Ed thanks for your answer. I think, I found my problem. I think I didn't configure the model editor properly. I'm trying to fix this. I thank you anyway.

After experiencing a little bit more with EMF, I found a link from Ed Merk in his Blog ed-merks.blogspot.de/2008/01/creating-children-you-didnt-know.html. Fortunately this describes the problem I have with my extending model. The extensions of my model should be displayed in the editor of my base editor. Unfortunately it doesn't work for me.

Has anyone the same experience and/or any hints?

Bugra,

Did you delete the plugin.xmls and regenerate them?

Hi Ed. Yes, I did delete them all from my extended model / edit / editor project. Are there any other configurations I should set? Am I right that the changes should be seen in the base editor?

Bugra,

That blog was pretty clear on what needed to be set in your GenModels; I
assume you did all those configurations already. Do you see the
additional registrations in your edit project's plugin.xml files?

Note that you've never been clear about what classes and what types of
references between them are involved and I can't begin to guess as such
things.

Hi Ed,

solved the origin problem but experiencing another one. Origin problem was; I didn't check the 'Extensible Provider Factory' to true (Sorry). The types and classes are from the example in the blog Resource and Link. Now I see the elements of the extending model in the editor and can select them. But the other problem I have now is, that if I choose such an element in the context menu (New | File, Folder, Link) the element is not visible in the editor, but it is described in the *.resource - modelfile when I open it with the text editor. Did you experience any error like that before?
