I have a strange problem :
When I drag and drop an element from a different jar and click save,
The Save failed the first time with the following error:
Save Failed
Cannot modify resource set without a write transaction
then when I redo the second time it works.
looks like the resource is locked or busy doing some operations how to get around of this problem ?
In fact when I save my icremental builder is executing another long task
how can I fix that so that the saving run in a different thread

It seems the problem was resolved using ICommandProxy;
SetRequest reqSet = new SetRequest(editPart.getEditingDomain(),
SuperNode, XXX, name);
SetValueCommand operation = new SetValueCommand(reqSet);
editPart.getDiagramEditDomain().getDiagramCommandStack().exe cute(
new ICommandProxy(operation));
But My problem is I want to do two operations :
- set the name
- add another subnode
So I created two operations and followed the above code:
for operation1 and operation2 like this:
SetRequest reqSet1 = new SetRequest(editPart.getEditingDomain(),
SuperNode, XXX, name);
SetValueCommand operation1 = new SetValueCommand(reqSet1);
editPart.getDiagramEditDomain().getDiagramCommandStack().exe cute(
new ICommandProxy(operation1));
SetRequest reqSet2 = new SetRequest(editPart.getEditingDomain(),
SuperNode, XXX, name);
SetValueCommand operation2 = new SetValueCommand(reqSet2);
editPart.getDiagramEditDomain().getDiagramCommandStack().exe cute(
new ICommandProxy(operation2));
At this time I got the exception.
So bottom line it works for one operation but not for two.
Any hints, help ? Thanks

The stack trace you show involves doing a save. How does that fit in
with what you're describing here?

I just encountered this problem. Here is the solution I came up with: do not propagate the notifications from the xmlns prefix map feature in my DocumentRootImpl like so:
/**
* <!-- begin-user-doc -->
* <!-- end-user-doc -->
* @generated NOT
*/
@SuppressWarnings("serial")
public EMap<String, String> getXMLNSPrefixMap() {
if (xMLNSPrefixMap == null) {
xMLNSPrefixMap = new EcoreEMap<String, String>(EcorePackage.Literals.ESTRING_TO_STRING_MAP_ENTRY,
EStringToStringMapEntryImpl.class, null) {
{
initializeDelegateEList();
}
@Override
protected void initializeDelegateEList() {
delegateEList = new DelegateEObjectContainmentEList<Entry<String, String>>(entryClass,
DocumentRootImpl.this, SwitchyardPackage.DOCUMENT_ROOT__XMLNS_PREFIX_MAP) {
@Override
protected void dispatchNotification(Notification notification) {
// don't forward the notification
}
};
}
};
}
return xMLNSPrefixMap;
}
