	40	In your Application constructor, set your custom editing context factory as the default factory for ERXEC as shown here for example:
	41
	42	{{code}}
	43
3.1	44	public Application() {
1.1	45	super();
	46
	47	// Configure the Editing Context factory for my subclass of ERXEC
	48	ERXEC.setFactory( new MyEditingContextFactory() );
	49
	50	// More app initialization code......
	51
	52	}
