Hey guys I'd like to deal with persisted data in order to save my Application Status before quitting. Well in order to give it a try I created a dirtyable object in an MPART then added a saving handler linked to a menu entry.

Here it's the MPART:

private Map<String, String> persistedState;
@PostConstruct
	public void createComposite(Composite parent) {
persistedState = part.getPersistedState();
----
	@Persist
	public void save() {
		dirty.setDirty(false);
		 persistedState.put("1", "myvalue");
		part.getPersistedState().putAll(persistedState);
	}

Then I removed the -clearPersistedState tag from the VM args.

Well the data persistence works like a charm if I close the MPart and reopen it again but it fails when I quit the application and relaunch it. In the latter case it's like the persistenceState is erased anyway.

Thanks
