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

I have applied in my local working copy a xpcom proxy mehanizm where I founded modification of DOM. 
It's add following benefits:
1) It's helps us to modify DOM in non ui JOB without interrupting user input. 
2) Also it's allow us to queue modifications event and in case when user modify some node several times, we applying only last modification.Without it's we apply all modifications.
problems: 
 If in VPE will be some place where DOM will be modified without proxy it's crashes a eclipse(I can't founded such places now), but  we should check all carefully.
 If it's suits for us, i can commit my changes.

Also I have tried to apply a delay before update visual preview, it's doesn't helped.

> 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).
