Hi all,
I am trying to implement a shared editing domain using the steps described in GMF Tips Sharing Single Editing Domain Instance Across Several Diagrams.
However, whenever I close a diagram, I get an java.lang.IllegalArgumentException: Cannot remove statically registered editing domain DiagramPartitioning.diagram.EditingDomain. See stack trace below.
The last step of this guide (#12) is to add method to the ???DocumentProvide class to correctly unload (model) resources associated with diagram. However, this method is already auto-generated by GMF tooling as:
/**
* @generated
*/
protected void disposeElementInfo(Object element, ElementInfo info) {
if (info instanceof ResourceSetInfo) {
ResourceSetInfo resourceSetInfo = (ResourceSetInfo) info;
resourceSetInfo.dispose();
}
super.disposeElementInfo(element, info);
}
The exception happens when calling resourceSetInfo.dispose(). In order to fix this problem, I am thinking about changing the dispose() method of ???DocumentProvide class to not dispose the editing domain when it is statically registered.
Change from:
/**
* @generated
*/
public void dispose() {
...
getEditingDomain().dispose();
}
To:
/**
* @generated NOT
*/
public void dispose() {
...
// Only dispose the editing domain if it was not statically registered.
String id = getEditingDomain().getID();
if (id==null || !EditingDomainManager.getInstance().isStaticallyRegistered(id)) {
getEditingDomain().dispose();
}
}
It seems to be working fine now, but I would like to know if anyone has a better solution for this problem.
Thanks,
Luis
