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.
Thanks,
Raymond
