Hello,
I've the problem, that my EClasses children (Changeable=true,
Container=false, Containment=true, Derived=false, EType=EObject, lower
Bound = 0, Ordered=true, Resolve Proxies = true, Transient=false,
Unique=true, Unsettable=false, Upper Bound = -1, volatile = false) are not
getting resolved by the AdapterFactoryContentProvider.
Id I debug the case, I see that the children list has entries!
Within the content providers getElements method the method "public
AdapterFactory getFactoryForTypes(Collection<?> types)" returns null, what
might be the reason (adapterFactoryDescriptorRegistry stays null and
delegatedGetFactoryForTypes always returns null).
What are I doing wrong? I'm using the latest Galileo EMF release. And I've
rebuild the model and the edit code plenty of times :)
Thanks,
Jan

Not sure what you mean by "getting resolved"...

Debugging what?

For the package of an EClass that fails to return an adapter, does it's
*.edit project have a registration like this:
<extension point="org.eclipse.emf.edit.itemProviderAdapterFactories">
<factory
uri="http://www.example.com/Library"
class=" com.example.library.provider.LibraryItemProviderAdapterFacto ry "
supportedTypes=
"org.eclipse.emf.edit.provider.IEditingDomainItemProvider
org.eclipse.emf.edit.provider.IStructuredItemContentProvider
org.eclipse.emf.edit.provider.ITreeItemContentProvider
org.eclipse.emf.edit.provider.IItemLabelProvider
org.eclipse.emf.edit.provider.IItemPropertySource"/>
</extension>

Note that plugin.xml files don't regenerate once the file exists...
Deleting it and regenerating it does the trick...

Jan,
Stepping through the logic in the composed adapter factory where it
tries to find a factory that's capable of dealing with the object that's
passed in is the only way I can think of.
