Hi there

If I want to chain services together where the result of one service will be input into another service then the result of the second service is the output of the main/parent service call how would I implement this?

E.g.

geovalidationChainJS service gets called.

Inside that service I have two services:

coordinateConversionJS then after that the results becomes input into another service called geoValidationPy.

The WPS XML response of geoValidationPy is what gets returned to the user when they execute geovalidationChainJS instead of the results being embedded instead the LiteralData? element.

Currently I get a normal WPS XML response when I execute coordinateConversionJS. I'm not sure how to parse the XML so I get the actual results of LiteralData? so I can manipulate that value and use as input into geoValidationPy. DOMParser and jQuery doesn't seem to work.

Thanks for your help.

Using a post request with RawDataOutput? returns first output regardless of the output identifier specified using a python service.

Versions affected: 1.2.0 1.3.0-rc1 - only tested with python process

See attached code for working example

zoo-project svn 229 Ubuntu 11.04 x86_64 with kernel 2.6.38-8 (up-to-date stable patches on ticket submission date) Python 2.7.1+ (r271:86832) from Ubuntu packages

Attached is the zcfg. When foo.py contains:

def Foo(conf,inputs,outputs):

outputsResult?value?=inputsa?value? return 3

everything works fine. When adding: input json to the beginning of the file, zoo returns a SEGFAULT exception. JSON module works fine in standalone python. Execution tested with:

./zoo_loader.cgi "request=execute&service=WPS&version=1&identifier=Foo&DataInputs?=a=foo"
