> after setting up the following query:
> //mycoreclass[@ID= 'ArchNachl_class_003']//label[@* = 'A']
> I get a NullPointerException:

> I don't really know if it's a valid query. I should search for every label that has a property value (what ever name the property may have) that is somewhere under a specific "mycoreclass" node. Either way Jackrabbit should of cause not exit with a NullPointerExeption here.
> I'm using the very current svn snapshot of jackrabbit. For the records line 550-557 of LuceneQueryBuilder.java look like this now:
> String field = "";
> try {
> field = node.getProperty().toJCRName(nsMappings);
> } catch (NoPrefixDeclaredException e) {
> // should never happen
> exceptions.add(e);
> }
