Hi, Ed,
I can't be AWOL as there is no protocol that requires leave. :-P
Besides, I can still participate in the newsgroups whenever I feel like
spending a little time ... and I plan to. I should still be able to
help until either my memory of the code fades or the code drifts away
from what I remember of it.

Hi, W.,
There is a brief introduction to the examples in the on-line help (if
you have the EMF Validation SDK installed, and not just the examples).
Look for the Examples Guide under the EMF Validation Framework Developer
Guide.
One point that the help doesn't mention is that it's a good idea to
install all three examples, especially as the OCL example contributes
some constraints that make it more interesting.

Thanks, Christian. I did install the Validation SDK and see the on-line
help from Eclipse.But, I dont understand how to run it. Here is the
Validation Example:

Are the EMF Validation Framework Examples are given in the three
org.eclipse.emf.examples.library related projects?

Should I run org.eclipse.emf.validation.examples.general by choosing run
as Eclipse Application to get the above description? How to create a
project in
the second Eclipse? I cannot see the submenu under validation menu? Thanks.

Hi, Wuwei,
The reason why the three EXTLibrary example plug-ins are installed with
the validation examples is simply to provide a model, that anyone can
easily understand, with which to demonstrate the validation concepts.
So, the validation example plug-ins contribute menu actions to the
EXTLibrary editor and constraints on the EClasses in the EXTLibrary
model. Have a look in the plugin.xml files to see this.
In your run-time workbench, just create a plain project and use the
"File -> New -> Other..." menu to create an EXTLibrary model instance
with a library as the root element. You will get the same kind of
editor that EMF always generates, except that the validation examples
have added a few actions.
HTH,
Christian

Thanks, Christian. It works.I also tried the adapter and OCL examples.
They all work. But, when I go back to validation.general plug-in,
I still see "The Evalidator Adapter succesfully delegrated validation
of ...", which I think did appear before running the adapter example.
Also, I dont give the name for the library when running validation.general
plug-in. But, I did not get the error msg. Does that mean I need to
remove the adapter plug-in example? Thanks.

Hi, Wuwei,
Right, the adapter example adds a "hack" (I think it's an early startup
extension, but I don't have the code with me to verify it) that replaces
the default EValidator for the EXTLibrary in the registry, by one that
delegates to the ModelValidationService.
Again, I don't have the code, but I think the library-name constraint is
a "live" constraint, so it will only trip if you select the "Enable Live
Validation" action in the context menu of the Resource or if you run
batch validation. It's also possible that the constraint is defined in
the OCL example plug-in ... the three really need to be used together,
and should probably be combined (there is a bug on that).
Cheers,
Christian

I still get confused here. Is it possible for me to remove the adapter
plugin
bc I want to get rid of msg "The Evalidator Adapter succesfully delegrated
validation of ...". More general question is after I install a plugin, is
it possible to remove that plugin later? Thanks.

Hi, Wuwei,
You need only to close or delete the plug-in project that you don't
want, then it will no longer be in your run-time workbench's configuration.
If you installed the example plug-ins into your development workbench
(which I don't recommend doing) then you would have to uninstall the
entire examples feature, because I don't think that p2 provides a UI for
removing a single plug-in (it would invalidate the feature, anyway).
Cheers,
Christian

Hi, Wuwei,
It sounds like you tried it on the wrong element. This action is
applicable only to Resources. What's more, the enablement is computed
at run-time, which requires Eclipse to create the action object when you
first select it in the menu, resulting in the message that you saw if it
isn't enabled. Also, once live validation is enabled for a resource, I
see in the code that it can't be disabled without closing and re-opening
the editor ...
Cheers,
Christian
