[Chiba-users] Using any other types than basic Schema types

[Tambet M. <tam...@gm...>]

Hi all!

I'm working on a WSDL2XForms generator and it already works quite well 
for my purposes. But I have a problem with xsi:type attribute, which I 
already mentioned in my previous post. I'll try to explain it in more 
generic way, maybe someone can help me.

Basically I need to use data type, which is not basic Schema type, like 
string or integer. It has to be declared in instance data with xsi:type 
attribute. The webservices I'm calling are expecting this specific type 
(soapenc:Array) and I'm not in position to change those webservices.

If I include xsi:type="soapenc:Array" in my instance data, I get 
NullPointerException from Chiba. Actually I get the same error with any 
other non-Schema type too. I've tried to define the type by including 
external schema with <model 
schema="http://schemas.xmlsoap.org/soap/encoding/">, but that didn't 
help. I tried to put schema inline, but that didn't change the error either.

Currently I'm considering options:
1. Change Chiba core to ignore all types it doesn't know.
2. Use proxy when submitting the data and in this proxy rewrite message 
to include needed xsi:type attributes. I could use for example attribute 
xsi_type and rename it into xsi:type in proxy.

What path you would suggest?
