I would like to know what is the best way to map my associations.

I have five Class on my metamodel that extends to my Entity Class, each one can be associated to the other (but not with itself), to simplify my metamodel I created a Class Association that have source and target typed with my Entity Class. So in the diagram my source and target can be anyone of my five Class.
The problem is that I need to set a diferent label for each kind of Association.
For exemple: 

A <-> B with Label = 'in'
B <-> C with Label = 'out'
A <-> C with Label = 'main'

So I created more five associations that extends to my Association Class. Each one with it default label.

But when I'm on the mapping step I don't know how to differ one association to the other. I think I can use OCL but I don't even know how to ...

One solution that someone did before me, is to create two association for each relation like this

association 1.1 : source(A) target(B) label = 'in'
association 1.2 : source(B) target(A) label = 'in'

But I think it's not a good solution


If someone have an ideia I would be glad.

Thanks

Hi,
I'm having the same problem defined here:
http://dev.eclipse.org/newslists/news.eclipse.modeling.gmf/msg02305.html

Basically the pasted element is not added to the model element and thus there are some changes I cannot make to the pasted element, also when I reload the diagram the pasted elements disappear

I'm wondering if someone who had encountered this issue before managed to find a solution?

thank you in advance,
Johan

I have a gmf editor with a custom ILayoutNodeProvider, I can call my ILayoutNodeProvider with "Arrange All" GMF actionSet button, layout is correctly executed.

Now I want this ILayoutNodeProvider be executed each time a Top Node is added to my Diagram.

Where can I insert my LayoutService.layout(...) call?
It seems in LayoutEditPolicy but this doesn't works.

Thanks.

I don't seem to understand what is the problem and why the loading of the gmfmap file fails. I have validated the gmfmap file I am using and it is just fine. The code I have implemented is the following:

@SuppressWarnings("restriction")
public GenerateDiagram(){


resourceSet = new ResourceSetImpl();

Resource genmodel = new ResourceImpl();
genmodel = resourceSet.createResource(URI.createPlatformResourceURI("/bt.com.ccm.generation.plugin/model/product.genmodel", true)); System.out.println("print genmodel: "+genmodel.toString());

Resource gmfgraph = new ResourceImpl();
gmfgraph = resourceSet.createResource(URI.createPlatformResourceURI("/bt.com.ccm.generation.plugin/model/product.gmfgraph", true)); System.out.println("print gmfgraph: "+gmfgraph.toString());

Resource gmftool = new ResourceImpl();
gmftool = resourceSet.createResource(URI.createPlatformResourceURI("/bt.com.ccm.generation.plugin/model/product.gmftool", true)); System.out.println("print gmftool: "+gmftool.toString());

Resource gmfmap = new ResourceImpl();
gmfmap = resourceSet.createResource(URI.createPlatformResourceURI("/bt.com.ccm.generation.plugin/model/product.gmfmap", true)); System.out.println("print gmfmap: "+gmfmap.toString());

resourceSet.getResources().add(genmodel);
resourceSet.getResources().add(gmfgraph);
resourceSet.getResources().add(gmftool);
resourceSet.getResources().add(gmfmap);

TransformToGenModelOperation tgmfgen = new TransformToGenModelOperation(resourceSet);


try {
NullProgressMonitor np = new NullProgressMonitor();

tgmfgen.loadMappingModel(gmfmap.getURI(),np);
tgmfgen.loadGenModel(genmodel.getURI(), np);

GenModel genmmodel = tgmfgen.findGenmodel();

IFile target = (IFile)new File("product.gmfgen");
tgmfgen.setGenURI(URI.createPlatformResourceURI(target.getFullPath().toString(), true));

			
		} catch (CoreException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}

//IProgressMonitor monitor = // (IProgressMonitor)getProject().getReferences().get(AntCorePlugin.ECLIPSE_PROGRESS_MONITOR);

NullProgressMonitor np = new NullProgressMonitor();
System.out.println("created IProgressMOnitor: ");
tgmfgen.setGenURI(URI.createPlatformResourceURI("/bt.com.ccm.generation.plugin/model/product.gmfgen", true));
tgmfgen.executeTransformation(np);
}

Any ideas?

Hello Aurelien,

How I do that :
- one top node for each "profile" with different "feature seq
initializer"
In addition to "feature sequence initializer" you have to add corresponding Constraints. This is important to let GMF diagram updater determine how to represent particular domain model element. E.G.:
- two node mappings referencing same metaclass with feature initializers 1. featureA -> value1 2. featureA->value2

In this case we have to create two constraints featureA = value1 / featureA = value2 for each of NodeMappings in accordance.

-----------------
Alex Shatalin



doesn't work so fine finally...

The problem is that featureA after being initialized can switch from value1 to value2... Or I have the constraint for the top node, so it disappears...

In addition, I want to have multiple initializers so, multiple values and so a lot of duplicate code. (if it was only generated code which was duplicated it wouldn't be so annoying but I customise display with another XXXeditPartProvider)


So is there another way to propose different initialization to the user?
Adding a menu item directly in the pop-up menu of creation?
other...
