I have an alternative editor which can be used to modify the name of my
object. I can modify it easily via the generated graphical editor. I see
that the commands used to accomplish this are derived from
org.eclipse.gef.commands.Command.
When I am editing the name in the alternate editor, I have access to the
semantic model but not the graphical editor - which is OK.
ControlType owner = getControl();
EditingDomain domain =
AdapterFactoryEditingDomain.getEditingDomainFor(owner);
EAttribute feature = DiagramPackage.eINSTANCE.getControlType_Name();
Command setCommand = SetCommand.create(domain, owner, feature, name);
domain.getCommandStack().execute(setCommand);
I tried the emf command first but the command is not actually executed
because the domain is 'read-only'. My model is stored in a database so it
doesn't follow the file, platform or any archive schemes.
Should I override the methods which test for read-only? To accomplish
reading and wrting I have a special resource type and output stream which
route the reading and writing from/to the database.
What is the purpose of marking the resource as read only?
So, I figured what command is used by GEF editor to set values in the model
and came up with the following replacement for command creatinon and
execution.
TransactionalEditingDomain tDomain = (TransactionalEditingDomain) domain;
Command setValueCommand = new SetValueCommand(new SetRequest(tDomain, owner,
feature, name));
tDomain.getCommandStack().execute(setValueCommand);
However, this approach doesn't even compile because in the code above the
Command is the org.eclipse.emf.common.command.Command and the one in the
graphical editor is org.eclipse.gef.commands.Command.
Should I attempt using gef command or make the resource writeable and get
the emf command to work?
Thanks,
Swavek

Swavek,
Specializing the read only computing in the adapter factory editing
domain seems reasonable. The idea there is that a resource can be read
only in the work space and in that case, you can't edit it. For EMF 2.4
we are working on generalizing the URI converter so that things like
isReadOnly, exists, and delete can be more easily implemented and
specialized.

You'll actually be able to delete an EMF resource and delete the
underlying IFile as a resource. There's even a prototyped for an
HTTP-backed repository...
