Intented behaviour for range -> source_node

[aindlq]

My understanding was that when range source node doesn't equal path.source_relation then range source node should be used as xpath that will produce range nodes. Is my thinking correct?

If so then there is a bug here -

x3ml/src/main/java/gr/forth/ics/isl/x3ml/engine/Path.java

Line 117 in f660cb2

String expression = path.source_relation.relation.get(0).expression;

Currently range.source_node is simply ignored when generating range node.

I guess it should be like this:

        String expression = path.source_relation.relation.get(0).expression;
        if (range.source_node.expression.equals(expression)) {
            expression = "";
        } else {
            expression = range.source_node.expression;
        }

Thanks for spotting that.
Yes, you are right (usually both source node and relation are the same).
I'll update it accordingly.
