[news.eclipse.modeling.m2m] [QVTO] Help with syntax for assigning values

[Toñi Reina Quintero <reinaqu@xxxxxxxxx>]

Hi again,

	as you may suppose for my previous posts, I'm working with the 
xhtml.ecore metamodel. That is, I'm trying to generate some xhmtl from 
my source metamodel.

	The problem comes when I try to assign a value for the class attribute 
of the li type. The xhtml code I'm trying to obtain is something similar 
to the following one:


<LI>
   <A CLASS="active" TITLE="News" HREF="./1-news.html"> News</A>
</LI>

For that, I have written the following constructor:

constructor xhtml::LiType::LiType(current: siteMap::Node, 
iter:siteMap::Node){
	
	a += object xhtml::AType {
		
		_class += 'active';
		
		href:='./'+iter.fullFileName();
		title:=guardTexts(iter.label, iter.name);
		text:= title;
		
	};
		
}

The error is in the line _class+='active'. class has been defined as a 
NMTOKENS datatype. And this datatype has been defined having as a base 
the java.util.List. I suppose the problem is the syntax, so my concrete 
question is how can I assign the active value to the attribute class in 
this case?

Thanks in advance,
	Toñi
