Subject RE: xsp:attribute generating a new element instead of an attribute in an already existing element
Date Tue, 31 Dec 2002 14:08:45 GMT
Hello Joerg.
 
I was expecting some error saying I couldn't create the attribute there, instead, I got an
unexpected (from my point of view) XML tree.
 
Tks

	Hello Luis,
	
	the change of currentDate doesn't change the constraints of the API. You
	can not create an attribute after you already have created an element or
	text. If you have such a dependency you must calculate currentDate
	before creating the XML (move the logic out of the XML data structure).
