Hello everybody.
I have to develope an application to modelize some controls of HTML
model which can be only into the "body" tag.
I have build a model with HTML, Head, Body and Div elements.
HTML
+ Head
+ Body
+ Div
+ Div
+ Div
Then I have built the figures and tools files and the maping file in
which root element is Body, because HTML and Head doesn't matter to me
in the editor.
When I build code, I get a class with an error in the method:
private static DocumentRoot createDocumentRoot(Body model) {}
I have corrected it using this code:
private static DocumentRoot createDocumentRoot(Body model) {
HTML html = XHTMLFactory.eINSTANCE.createHTML();
html.setBody(model);
DocumentRoot docRoot = XHTMLFactory.eINSTANCE.createDocumentRoot();
docRoot.setHtml(html);
return docRoot;
}
Now my program runs ok but when I try to save the diagram an error arises:
"Cannot modify resource set without a write transaction"
How can I correct this error? Which is the mistake?
Thanks in advance.

Hi again.
I have notice that my mistake can be other. The model I described
earlier wasn't exactly my model.
First of all, I have a model (X) with controls (A, B, Group, ...) that
will be included in HTML model to rich it. I have done the ecore, model
and diagram code of it to have classes like EditParts which I will use
then in HTML diagram editor.
After this, I'm doing the same with HTML model but including this X
model into it. I'm enhacing the Group so it can contain HTML divs too.
When I build the model code it is implemented in a class that extends Group.
I can make an EMF editor using two models at the same time but when I
create gmf (graph, tool, map, gen) files and generate code, my problem
arises. In the maping file I use "load resource" to include X model
maping file, and then I can add nodes and tools from it. If I include a
control from this model the problem arises but if I only use divs it
doesn't.
I think that this makes the program a litle more complicated. It's not
the same that I explained before.
Does somebody knows how to resolve this problem or how to implement the
inclusion of GMF generated clases of a diagram into another to use them
in the second one.
Thanks in advance.

Hello.
I have found the problem but I don't know how to solve it.
Doing a trace of the code I have found that the exception rises when the
namespaces are write to the resource, exactly in the method endSave of
the class XMLSaveImpl, when a notification is dispached (I think) in the
line
xmlnsPrefixMap.put(key, value);
What should I do to avoid this problem. Can I run the save method in a
write transaction? How should I implement this?
Thanks in advance.
