Hello,
I'm back with another problem. I need to obtain a in memory
representation, of the workflow modelled with GMF/EMF in order to deploy
it on a server. Searching on the archive I found this:
http://dev.eclipse.org/newslists/news.eclipse.tools.emf/msg1 8706.html
that answer to my question building a org.w3c.dom.Document. I wrapped
the code in a subMenu action, and in the selectionChanged method, I get
the WorkflowTypeEditPart in order receive the editingDomain (am I
right?). This is the run method:
public void run(IAction action) {
DocumentBuilderFactory documentBuilderFactory =
DocumentBuilderFactory.newInstance();
documentBuilderFactory.setNamespaceAware(true);
DocumentBuilder documentBuilder;
try {
documentBuilder = documentBuilderFactory.newDocumentBuilder();
Document document = documentBuilder.newDocument();
ResourceSet resourceSet =
mySelectedElement.getEditingDomain().getResourceSet();
for(Resource resource:resourceSet.getResources()){
((XMLResource)resource).save (document, null, null);
}
TransformerFactory transformerFactory =
TransformerFactory.newInstance();
Transformer transformer = transformerFactory.newTransformer();
transformer.transform(new DOMSource(document), new
StreamResult(System.out));
}
and this it the error I receive:
org.w3c.dom.DOMException: HIERARCHY_REQUEST_ERR: An attempt was made to
insert a node where it is not permitted.
at org.apache.xerces.dom.CoreDocumentImpl.insertBefore(Unknown Source)

I suppose is something wrong with the ResourceSet (debugging I notice
that the exception is raised after few iterations), but I don't know how
to solve the problem. Any help would be more than appreciated :)
Cheers
Nicola

Nicola,
If you just tried to save to an string writer and checked the result, is
it well formed XML?
currentNode =
currentNode.appendChild(document.createElementNS(nameInfo.ge tNamespaceURI(),
nameInfo.getQualifiedName()));
Given the above line, I'm suspicious that there aren't perhaps two
features set on the document root and hence it's trying to create two
root elements...

Hello Ed,
thanks for the hint! I solved the problem following your hint. The
resourceSet contains two resources thus in the second iteration the
Document class was complaining. I solved changing the code in this way:
for(Resource resource: resourceSet.getResources()){
if(resource instanceof ModelResourceImpl)
((XMLResource)resource).save (document, null, null);
}
Even if I struggled for a while with GMF/EMF for a while, some concepts
are still mysterious:)
Again thank you!

Nicola,
Oh, I see the problem now. You might and do end up calling this for
multiple resources so you really ought to have a break statement or not
be doing it in a loop.
