Hello,

My question is continuing on the following:
http://www.eclipse.org/newsportal/article.php?id=1045&gr oup=eclipse.modeling.mdt.ocl#1045

The getConstraints() of ModelValidationService seems only be called once.
I am still not find a way to update the constraintCache inside the
ModelValidationService.

I tried to write a my own ModelValidationService, but it need the elements
to configureProviders(IConfigurationElement[] elements).

I want users can change the .ocl file to do validation again without
restart the eclipse.
Could you tell me is there any way to do it Or it not impossible at moment.


Thank you in advance.
wong.

Hi, Wong,

In my reply on that other thread, I said:

-----8<-----

If your provider is registered in the plugin.xml using cache="false" in the
<constraintProvider> element, then the framework should not be adding it to
the ConstraintCache provider that caches constraints.

If this is happening to your provider, then that is a severe bug. In that
case, a bugzilla with a reproducible test case would be much appreciated.

----->8-----

Cheers,

Christian

Hello Christian,

I think I did not say it very clearly. I just add cache="false" on
following which is your ocl example, it does not work for me.

I want uses are able to update the *.ocl file in the eclipse runtime from
the example of '<!-- Custom constraint provider using OCL documents -->'

-----------------------------------------------------------
<extension
point="org.eclipse.emf.validation.constraintProviders"
id="oclProvider">

<!-- Custom constraint provider using OCL documents -->
<constraintProvider

class=" org.eclipse.emf.validation.examples.ocl.OCLConstraintProvide r "
category="Constraints from an OCL Document"
cache="false">

<package
namespaceUri=" http:///org/eclipse/emf/examples/library/extlibrary.ecore/1. 0.0"/>

<ocl path="constraints/library.ocl"/>
</constraintProvider>
</extension>
</plugin>
----------------------------------------------------

Thank you very much.

Wong.

Hello, Christian.

I got it works. Thank you so much.

All my bad. I set the inv name started with digit. So it did not work.
"inv 1rule: self.courseGoals->notEmpty()"

I really appreciate your help.

Thank you very much.

Wong.

Hi, Wong,

Good! I'm glad it's working for you, now.

I think this problem with the initial digit is probably more of an issue in
the parser grammar than it is a violation of any naming rules in OCL/UML
(there generally aren't any). Probably not worth worrying about :-)
