Possible error in Shared Editingdomain tutorial [message #173271]

I've tried to setup shared editingdomains numerous times without success.

But today I gave it another shot, and did it!

The thing that made it work was instead of doing:

<extension
point="org.eclipse.gmf.runtime.emf.type.core.elementTypeBindings ">
<clientContext id="Diagram2_IDClientContext">
…
</clientContext>
<binding context="Diagram2_IDClientContext">
…
</binding>
</extension>

I did:

<extension
point="org.eclipse.gmf.runtime.emf.type.core.elementTypeBindings ">
<clientContext id="Diagram2_IDClientContext">
…
value="SharedEditingDomain"/>
</clientContext>
<binding context="Diagram2_IDClientContext">
…
</binding>
</extension>

Can anyone else confirm this? (Also, many of the steps in the tutorial
could be simplified, and some cut out - the procedure is quite straight
forward..)

Cheers,

Tomas

Hello Tomas,

> value="SharedEditingDomain"/>
Was this the only difference between two quoted plugin.xm fragments?
I think this property should be the same for both generated editors - then
you perform step 6. (of http://wiki.eclipse.org/GMF_Tips#Sharing_single_EditingDomai n_instance_across_several_diagrams)
and step 7..

Yep.

Ok.. Somehow this didn't happen for me..

Also, I needed to implement:


<extension
point="org.eclipse.emf.transaction.editingDomains">
<editingDomain

factory="org.eclipse.emf.workspace.WorkspaceEditingDomainFactory "
id="SharedEditingDomain"/>
</extension>


....for both diagrams to make it work.

All is not well however, I get random errors when I delete something in
the diagrams. "The object xyz is not contained ..." Any Ideas?

Yes, extension is necessary.

Are you getting this error on trying to save diagram or just on pressing
"del" key?

Yes. Looks like this code is necessary.

Some incomming references was not removed on deleting the lementt from diagram
or? Do you have this error on trying to save diagram or just on pressing
"del" key?

Thanks for helping Alex :)

I get this when I try to save, not on delete.

Then looks like some incomming references was not set to null. You can try
debugging delete command to see why.

Hi,

you should use a DiagramEditingDomainFactory in your plugin.xml instead
of a WorkspaceEditingDomainFactory since the
WorkspaceEditingDomainFactory does not attach a CrossReferenceAdapter to
model objects. This adapter is used for tearing down incoming and
outgoing references to prevent dangling references.

Use


<extension point="org.eclipse.emf.transaction.editingDomains">
<editingDomain
factory=
"org.eclipse.gmf.runtime.diagram.core.
DiagramEditingDomainFactory"
id="SharedEditingDomain"/>
</extension>


instead of


<extension point="org.eclipse.emf.transaction.editingDomains">
<editingDomain
factory=
"org.eclipse.emf.workspace.WorkspaceEditingDomainFactory"
id="SharedEditingDomain"/>
</extension>


Maybe
http://wiki.eclipse.org/GMF_Tips#Sharing_single_EditingDomai n_instance_across_several_diagrams
should be updated.

Best regards
Manuel
