Description	Flags
perl api test for system.setChildChannels	none

Description Stephen Herr 2008-07-14 19:33:23 UTC

Description of problem:
The system.setChildChannels API method is supposed to accept an "array" of
arguments according to the published API. The purpose being so you can subscribe
to more than one child channel per call. The backend functionality does not
work; it throws an error. See system.deleteSystems for an example of a working
method that accepts an array as an argument. We can either 1) make the list
functionality work or 2) change the api to correctly identify that you can only
operate on one channel at a time.

Version-Release number of selected component (if applicable):
5.0.6

How reproducible:
Always

Steps to Reproduce:
1. Run attached perl script.
  
Actual results:
Fault returned from XML RPC Server, fault code -2: unhandled internal exception:
java.lang.Integer

Expected results:
2    (indicating both channels were successfully subscribed)

Therefore, the limitation is in the client tool, not API.
