[news.eclipse.modeling.m2m] [QVTO] Question about intermediate propertie

[Toñi Reina Quintero <reinaqu@xxxxxxxxx>]

Hello everybody,

	Although I have said in the subject the question is about intermediate 
properties, I'm not sure if it has to do with them or with OrderedSet 
assignments.

	I have defined a intermediate property called nodesMainNav. This 
property is an Ordered Set of Nodes.

        In the transformation entry point I'm trying to fill in the 
Ordered Set. For that, I executed a query named getMainNavigationArea, 
that returns an Area, and as an Area is composed of a set of Nodes, I 
use the relation nodes to extract all the nodes of the area. As it can 
be seen in the piece of code I show below.


intermediate property siteMap::nodesMainNav : OrderedSet(siteMap::Node);


main() {
	
	inModel.nodesMainNav := getMainNavigationArea().nodes;
    	log('1..Num nodos',inModel.nodesMainNav->size());	
	inModel.rootObjects()[siteMap::Sitemap]->map toWebSite();
	
}

My problem is that the log sentence that appears as '1..Num nodos' shows 
the number of nodes in the OrderedSet is 0. However, I have written a 
similar log sentence inside the getMainNavigationArea query, and the 
result is that there are 8 nodes in the Area.

My question is: why does the OrderedSet seem to be without any nodes 
outside the query? Is this related to the intermediate property or is 
something related to the assignment?

Best regards,
	Toñi
