[Bug] Collection.removeResource( resource ) does not work when resource is derived from XPathQueryService
Test Case: An xpath query is issued to retrieve document resources that
need to be removed.
collection.removeResource( resource ) does not work when resource is
derived from the XPathQueryService. It looks as if the reason may be
because the resource.getId() is null when coming from the
XPathQueryService.
What could be the problem?

RE: [Bug] Collection.removeResource( resource ) does not work when resource is derived from XPathQueryService
Posted by Kevin Ross <Ke...@iVerticalLeap.com>.
This doesn't make any sense from an API perspective.
1. To remove a resource, I need a Resource object.
2. I can get a list of Resource objects via the XUpdateQueryService
If the Resource object from the query service isn't 'real', then why is
it a Resource object? And if I can't use that Resource object for
removal via the Collection.removeResource( Resource), then why on
earth does it exist?
Thanks for your pointer Vanessa, I'll find that message and use the
workaround until this is resolved.

As far as I understand it (which isn't very far!) this is the expected
behaviour. Why it is this way isn't clear to me, though. If you look in
the archives a few days back I posted a question about this behaviour,
including a code snippet for how I got around it. It might help you if
you just need to get your problem solved quickly.
