RE: [Babeldoc-devel] retrieving a document from the journal

SourceForge Headquarters 1320 Columbia Street Suite 310 San Diego, CA 92101 +1 (858) 422-6466

OK that looks like exactly what I need.  However, I don't know the names for
the subparameters ahead of time (in my HttpClientPipelineStage), so I am
using getOptionList() to get a NameValuePair[].  This seems to be OK except
that if
my pipeline doesn't specify _any_ values for yourstate.options, I get a
NullPointerException thrown from PipelineStage.getOptionList().  Is this a
bug or is there a syntax I should use to specify no values?  I tried:
yourstage.options=
and got the same NullPointer as just leaving it out altogether.

This can be quite easily done as:

yourstage.options.key0=value
yourstage.options.key1=value
yourstage.options.key2=value
yourstage.options.key3=value
yourstage.options.key4=value

Like the XPathExtract and Router stages.  There is API support that will 
basically return an array of Pairs (Name/Value) from the options 
configuration.

PipelineStage.getOptions

Bruce.
