Problem with loc namespace

[BURGHARD Éric]

Hi,

I'm using eXist XQueryGenerator in a simple pipeline. It works correctly
when i call it directly from my browser with correct parameters.

Now this pipeline is called from
o.a.c.w.a.c.PipelineAuthenticator.authenticate(PipelineAuthenticator.java:145)
during a flow flogin and i've got an exception

org.exist.xquery.XPathException: No namespace defined for prefix loc

Any idea ?
