[Xsltforms-support] Two defects in xforms.close method

[Ivan P. <ipo...@ma...>]

Dear Alain,

as soon as our date picker bugfix proved to be useful, maybe you will 
find some time to include another piece of our code in /trunk, so we 
will not have to continue merging our patches into your code? Thanks a 
lot in advance!

As I wrote once, we are dependent on xforms.close() method, because we 
are showing and hiding XForms dynamically using AJAX without page 
reload, and the problem is that standard version of xforms.close() 
actually doesn't clean up everything!

This causes two problems I reported earlier, this one:

http://sourceforge.net/mailarchive/forum.php?thread_name=4D332B30.8070300%40mail.ru&forum_name=xsltforms-support

and the first of the two given here (thanks God, we're completely 
finished with the second one): 
http://sourceforge.net/mailarchive/forum.php?thread_name=4D3A0CE5.4020709%40mail.ru&forum_name=xsltforms-support

We solved both of them, here is a solution:

in xforms.close method, after xforms.dispose(... (1627) the following 
code should be inserted:

	Calendar.INSTANCE = null; /*so the next time this object will be 
recreated and all event handlers will be bound properly*/
	dropHasXFElement(document.documentElement);

where

/*Just full recursion over the whole DOM to remove hasXFElement 
attributes that will spoil everything the next time!!*/
function dropHasXFElement(element){
	element.hasXFElement = null;
	var subelement = element.firstChild;
	while(subelement){
		if (subelement.nodeType == NodeType.ELEMENT)
				dropHasXFElement(subelement);
		subelement = subelement.nextSibling;
	}
}

Ivan Ponomarev.
