Hi
I applied the procedure under Live validation and quick-fixes in GMF-based editors with EVL ( http://www.eclipse.org/gmt/epsilon/doc/articles/evl-gmf-inte gration/ ) . with the gmf example project : mindmap project to validate the elements on the editor.
But the evl file validation does not happen. Can anybody please provide some help.
The elements in the mindmap example are Topic ,Resource , so on.
So I have modified the evl file as below :
*******************************************************
context Resource {
constraint HasName {
check : self.name.isDefined()
message : 'Unnamed ' + self.eClass().name + ' not allowed'
}
}
context Topic {
critique NameStartsWithCapital {
guard : self.satisfies('HasName')
check : self.name.firstToUpperCase() = self.name
message : 'Folder ' + self.name +
' should start with an upper-case letter'
fix {
title : 'Rename to ' + self.name.firstToUpperCase()
do {
self.name := self.name.firstToUpperCase();
}
}
}
}
*******************************************************
Additional details :
I am using eclipse 3.5 and jdk 1.6
mindmap example location as below:
cvs repository location --
host name : dev.eclipse.org
cvspath : /cvsroot/modeling
username :anonymous
password :
under head -> gmf-> examples -> check out the following :
org.eclipse.gmf.examples.mindmap
org.eclipse.gmf.examples.mindmap.diagram
org.eclipse.gmf.examples.mindmap.edit
After checking out :
To this I applied the procedure under 'Live validation and quick-fixes in GMF-based editors with EVL ' ( http://www.eclipse.org/gmt/epsilon/doc/articles/evl-gmf-inte gration/ ) .
I have made the manifest file changes to the manifest file in the org.eclipse.gmf.examples.mindmap.diagram package and created a new package contaning evl file under the 'src' in the org.eclipse.gmf.examples.mindmap.diagram package.
All the extension point changes also done to the org.eclipse.gmf.examples.mindmap.diagram package plugin file.
then launch a eclipse application runtime and create diagram file in general project. And I am trying to validate this diagram file.

Hi
Thanks a lot for the help on evl . It is working fine now.
I just have a doubt on copy paste of elements .Copy paste of elements does not work.
We had managed to solve this problem in gmf 2.2.0 by changing
resource type to XMI and
user uuid = true
But with the release of gmf 2.2.2 the copy paste does not work again.It would be really helpful if anybody could provide some suggestions on how to get this problem resolved or what could be changes that would have affected this feature or suggest any other eclipse feature/plugin that could help achieve copy paste of elements.
I am aware that this is not the gmf forum but if anybody has found some solution or workaround then it would be really helpful if u could share it.
Regards
Sowmya

Hi,
Is validation turned on in the mindmap editor? If not, could you please
turn it on and give it another go?

Hi
Both the flags - Enabled and Validation Decorators have been turned on in the .gmfgen project. But when i click on the validate option under Diagram menu, there are no validation errors.
It isnot an editor created using EuGENia
I have aother question :
2> If an element is referring to an external file (audio/video/text) and the file is in another folder in the same project folder. I want to check if the referred file is present in that location or has been deleted. Is it possible to perform this type of validation also.
Regards
Sowmya

Could you please send me your code at dskolovos gmail com so that I can
have a look?

This is possible but you'll need to implement a custom tool in java and
call it from EVL as per
http://eclipse.org/gmt/epsilon/doc/articles/call-java-from-e psilon/

Hi Sowmya,
The reason why the EVL constraints are not evaluated is that the wrong
namespace URI is specified in the constraint binding (it should be
http://www.example.org/mindmap instead of mindmap). Once the namespace
URI is set to http://www.example.org/mindmap, the constraints are
evaluated.
Note that there are a few errors in samplevalid.evl including a leftover
constraint on the Sync class from the filesystem example and a call to
satisfies("HasName") which produces an error as no HasName constraint
has been specified for Resource. Once you fix these it should all run fine.
Cheers,
Dimitris
