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?
To answer my own question, this would be unmarshalled as an array of
length 1 containing a single null. This seems correct. Unfortunately
it seems that there is no way to disambiguate this case from the null
array case. I will do some more investigation into this.

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)
