Hi ,

I want to validate my model using EMF validation framework.
If i have to achieve this using GMF(i.e, EMF validation invoked through
GMF).
Pls let me know if this is possible, and if possible how should i go about
achieving the same.

can i make use of the org.eclipse.emf.validation.constraintProviders
extension in
the GMF projects plugin.xml to define my project specific constraints.
Is it possible to register the constraints of the model (EMF model) with
validation service through GMF's plugin.xml file.

Regards
Senthil

To further add to Radek's explaination,

I did the following steps

1. Created OCL Constraints in Ecore as Annotations.
2. Used the templates that are available in
http://www.eclipse.org/articles/Article-EMF-Codegen-with-OCL /article.html
article. These templates generate code that enforces the contraints using
EMFT framework.
3. Enable the validation in gmfmap.
4. Audit rules that one can implement in gmfmap actually implements the
org....constraintproviders extention point enforcing the constraints
specified in audit rules that is availabe in plugin.xml
5. With out this audit rules the constraints in ecore can be validated in
the diagram plugin by using Diagram -> Validate.

Madanagopal.
