Common editor for model + model extension [message #687522]

Hello,

I have an Ecore Model 1 of type

AbstractChild

MyContainer
- children : AbstractChild

I have a second Model 2 in a different plugin extending Model 1 declaring

ConcreteChild->AbstractChild

I have generated a default Editor for Model 1 and Model 2 but did not
manage to see "add ConcreteChild" in the Context Menu of a
MyContainer-instance.

How can I easily create one common Editor, even if there is a growing
number of extending model plugins ?

There's an extension point that is used for this purpose, i.e. let other
plugins contribute child creation actions for additional subclasses.
However, when you generate the base editor, you must enable it by
setting the Child Creation Extenders option (Edit category) of the
EPackage genmodel element to true.

Thank you Hallvard,

that works for me.
I found the corresponding article knowing the correct key words now:
http://ed-merks.blogspot.com/2008/01/creating-children-you-didnt-know.html

Unfortunatelly the extension was not created automatically for my
existing projects so i had to try myself around with sample projects
from the scratch.

The extension I manually had to make is:
<extension
point="org.eclipse.emf.edit.childCreationExtenders">
<extender
class="de.tragwerk.solution.statics.combination.ui.kombinationUi.provider.KombinationUiItemProviderAdapterFactory$EditorChildCreationExtender"
uri="http://www.tragwerk-software.de/solution/editor">
</extender>
</extension>

which must be declared at the extending edit plugin.

Yes, EMF does not overwrite or edit plugin.xml if it already exists.
This is a long-standing problem:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=150092

I think that EMF at least should generate a plugin_gen.xml, to help the
user merge by hand.
