hi,
I'm trying to add a custom comparator to a 'related' tag. I know how to
do this for a simple 'listnodes' tag:
implement a comparator:
<%!
// sorts suitcases
// 1 2 3 12 23 88 xx1 xx12 xx3 xx9
// so more than 9 'xx' suitcases will still be a problem
static public class MyComparator2 implements java.util.Comparator {
public int compare(Object node1,Object node2) {
String no1 = ((Node)node1).getStringValue("no");
String no2 = ((Node)node2).getStringValue("no");
if ( no1.length() < no2.length() ) {
return -1;
} else {
return no1.compareTo(no2);
}
}
}
%>
and use it like this:
> <mm:listnodes type="suitcases" comparator="MyComparator2">
But how would I implement a comparator that works in a case like the
following:
> <mm:related path="urls,suitcases" comparator="MyComparator3">
So this one has 2 builder types to list.
When I print the class of the node that gets passed to the comparator it
looks like this:
class org.mmbase.bridge.implementation.BasicNodeNODE
It seeems to contain info about both urls and suitcases, and if I
specify fields="suitcases.no" in the related tag and I print the node it
shows like this:
>
prefix='',suitcases.no=1:'17',users0.number=9:'14436',urls.number=9:'14940',suitcases.number=9:'14488'
however, I cannot get the 'no' field by doing:
> String no1 = ((Node)node1).getStringValue("suitcase.no");
I hope someone knows what I missed/misunderstood.
cheers,
Simon Groenewolt
