Validation - constraintProvider - package [message #80847] Tue, 24 April 2007 11:33 Go to next message

Hello,



I have a model divided to many packages. In one of my package I have defined
interface ExpressionHolder with feature Expression. In other packages I
implement this interface. I want to add constraint to check expression in
any place where someone use ExpressionHolder.



I create 'constraintProvider' and 'constraint' for type ExpressionHolder and
this works but I must list any packages that probably use my interface. Is
it possible to not include all that packages but only base package (I want
to someone may create own model for some extension in the future)?

Hi, Grzesiek,

I see that there is an early filter in the determination of the constraints
applicable to an EObject, that checks the EObject's EClass's EPackage
against the packages declared by the constraint provider (in the default
XML-based implementation, that is; custom providers can behave
differently). This will prevent the framework from consulting the
provider, which constraints would correctly determine (by EClass
inheritance) that they apply.

The EPackage filtering should account for the possibility that one package
"extends" another. Would you mind raising a bug?

Thanks

I create request:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=183917

I have one more question to you. I use your's pattern of workbench
integration from EXTLibraryEditor
(org.eclipse.emf.workspace.examples.library.editor).
Few days ago I migrate application from Eclipse 3.2 to 3.3 and I get some
strange results.

I have two editors for different models (form different epackage) based on
common parts (abstract editor). In my operationHistoryListener I use code:
ResourceUndoContext.getAffectedResources(event.getOperation( ));
but for some reasons in one of my editors it returns empty set. I debug this
and discover that in first editor I have command with two undoContexts:
org.eclipse.core.commands.operations.UndoContext
org.eclipse.emf.workspace.ResourceUndoContext
and in this not working I have only that first context. I don't understand
why I have different contexts because both command is from shared page of
editors.
I don't know where those contexts are set to commands. Do you know how to
debug this sytuation?

Hi, Grzesiek,

Your English is very good.

I suspect that your WorkspaceCommandStack perhaps isn't being notified when
commands are executed in your second editor. Try putting a breakpoint at
the beginning of the

WorkspaceCommandStackImpl.DomainListener.resourceSetChanged( ...)

method to see how it computes the affected resources and whether it retains
them. The resources should be stored in the affectedResources field and
later converted to ResourceContexts in the historyNotification(...) method.

HTH,

Christian

Hello,



I found that place few minutes ago. Like you said method resourceSetChanged
was not called in my second editor - I simply load second model outside of
EditingDomain (directly by ResourceSetImpl) ;D



Thanks for help
