Save disabled [message #1121329]

Hi,

for some reasons it seem that the save button in my EMF editor is disabled:

index.php/fa/16330/0/

Which method responsible for determing if a save is needed? IsDirty in my xxxEditor?:

public boolean isDirty() {
   return ((BasicCommandStack)editingDomain.getCommandStack()).isSaveNeeded();
}

Cheers,
Phil

Phil,

Yes, the isDirty method should compute that.

I had a closer look at the isDirty method and it turned out that every time I add something to the model it returns true and if I undo this it returns false. So it seems to work as expected, but save is still disabled. What can be another reaon for this?

Cheers,
phil

Phil,

Unfortunately I'm not psychic... Note that generated editors have code
like this:

// Add a listener to set the most recent command's affected objects
to be the selection of the viewer with focus.
//
commandStack.addCommandStackListener
(new CommandStackListener()
{
public void commandStackChanged(final EventObject event)
{
getContainer().getDisplay().asyncExec
(new Runnable()
{
public void run()
{
firePropertyChange(IEditorPart.PROP_DIRTY);

I.e., it ensures that the the dirty state is checked by the editor...

Hi Ed,

thx for your patience with me. I had a look at the code you mentioned and it turned out that it's called every time I change something in the model. So this mans the editor checks the dirt state (which is true) then and should enable saving?

What I also observed:

- "Save all" works as I expected - every time the model change, "Save all" is enabled and I can save my model.

- when I close the file, the question "..has been modified. Save changes?" occurs and I'm able to save my model.

Yes, the enabled state of the save should reflect what the isDirty
method returns.

That might well be the case because at least one editor has save enabled...

Is something changing the underlying file system without using the
Resource APIs?

In the end, you really need to use the debugger to track down such
problems (and the "error while deleting" problem) yourself...
