Hello All..

In my gmf project any changes to model file is not enabling save option.

I had my old project where the my XXXDocumentProvider was extending
StorageDocumentProvider.

And changes made to model file using Impl.SetXX Methods was enabling save
button.

But upgradation of eclipse and gmf version save button is not enabling the
save button..

And now my XXXDocumentProvider is extending AbstractDocumentProvider.

Please help me...Or is any way to make editor dirty on a operation.

Regards
Govind R

Hello govind,

inner class XXXDocumentProvider.ResourceSetModificationListener is responsible
for marking and editor dirty on any modifications. The precondition is: "setTrackingModification(true)"
mode should be correctly supported by al the resources used by this diagram
editor. You can try debugging this class to see why diagram editor was not
marked as dirty.

Hi Alex,

i found that both my diagram and model file are resource which are coming
in notifyChanged of createEditingDomain() method
ie.setTrackingModification(true) is true.

But what i found was when i set the first value using Impl.setMethod say
setName() is notifyChanged(Notification notification) of
ResourceSetModificationListener is called and its shows
nextResource.isModified() is true.

and when i call again one Impl.setMethod say setAddress. at that time
nextResource.isModified() is false. i am setting the both name and address
in okPressed of Dailog.




The same code is working i n my old gmf version.

Please help as i dont want to revert back t my old version.

Regards
Govind R

Hello govind,

Try determining the reason of setting back "isModified" property to false...
It looks strange - i doubt there is an error in this place in EMF...

Hi Alex.


Ya get IllegalStateException:Cannot modify write transaction exception.

But this used to come in my old version but editor was dirty.

What exactly happens when we call setMethod .ie.. its sets new value to
attribute and nofify is called. but nothing excecutes after this.

You have to use transation. Try subclassing AbstractTransactionalCommand
+ execute it using IOperationHistory.execute().

> But this used to come in my old version but editor was dirty.
This is strange - transactions should be used to modify model in GMF.
