Maxim Areshkau commented on JBIDE-675:
--------------------------------------

I have been looked up intro 3-directions under fixing this bug:
	
	1)Cashing of VPE data , in this way we should resolve following problems:
		a) in class VpeCreation data contains field data, which should be properly cloned for cash(We should copy ns** objects and just save a link for w3c elements), but in this field every template can write everything.
		b) we have some memory links in mozilla(following error message *** _NSAutoreleaseNoPool(): Object 0x7105e080 of class NSConcreteValue autoreleased with no pool in place - just leaking), this can cause a crash of eclipse.
		c) I have tested work of VPE on page emplayes.xhtml and in case when cash a on, vpe forks up 2x faster.
	
	2)Second thing that I tried to do it's separate  update view of vpe from user ui thread. Processing under xulrunner objects should be called from ui thread, but eclipse usually creates only one instance of Display class, so when we run update in UIJob it's shows WAIT CURSOR and suspend user input on source page.When I run update of visual preview in non ui job it's crashes eclipse.
	
	3)adjust of processing notifyChanged event's.But in this case we should change event processing in VpeVisualDomBuilder and change mechanism of processing templates.

> When editing JSF files That contains quite a lot of include, it take commonly up to 20 seconds for one character i type to get it's way to the screen. I can even see, after 10 seconds, the cursor goes on step right, and after a new 10 second the character appear in front of the cursor. This make it impossible to use JSF editor from exadel to edit such file, i have to ressort to plain xml editor without completion for facelets tags.
> I will be posting attachement containing description of files involved (sorry, no file content).
