[kepler-dev] problem with type name mapping in WebService actor

[Ilkay Altintas]

Hi Karen,

Your fixes last year seemed to break the execution of other array  
types. So an update by Zhiming Zhao was provided on:

[1] The parsing for array type; mainly in configureActor() and  
createPorts(Parameters params).
[2] The serialization for string array; in _sendOutput().

If there's a fix you could check in that supports all array types,  
that would be great.

As a side note, we're updating the web service actor completely to  
allow for basic, array and complex types. We'll keep the old version  
of the actor around (maybe only in the archive) so there's no harm in  
fixing that version.

Daniel Crawl from SPA is working on this.I you could send him the url  
for your web service, he could test it with the new version.

Daniel: Could you please check in a clean current version of the new  
web service actor with some test cases.

Thanks,
-ilkay
