Raymond Feng commented on TUSCANY-2275:
---------------------------------------
Hi,
I debugged the issue and it turned out an interesting case.
1) When the client side pass 'null' for the service.processBean() method, the
body of soap message becomes:
<ns1:processBean xmlns1="..."/>
It's the wrapper element with empty children.
2) On the receiving side, the empty data get converted into SimpleBean[0] which
is an empty array of SimpleBean.
3) The user code in SimpleServiceImpl.java only tests if the simpleBean==null and
it causes an ArrayOutofBoundException. Adding the test of simpleBean.length>0
fixes the problem and the client runs successfuly.
I would resolve it as a user error. I'm not so sure if we should present the
data as null or [0]. If you can find any spec covering this corner case, I
would be happy to revisit it.
I think the marshalled form should be a wrapper containing a Bean
element with xsi:nil="true", not an empty wrapper. Would this be
unmarshalled as null instead of an empty array?

Thanks,
Raymond

please find the attached sample to reproduce it.
please note that this error was on client side and can be generated using
attached sample...
same works for servcie having bean (not an array of bean)
