Daniel Kulp commented on CXF-1737:
----------------------------------
Thanks for the testcase. Very useful.
The "correct" fix is actually on line 618:
if (!initializeParameter(o, method, -1, paramType, genericType)) {
return false;
}
should change to:
if (o.hasOutput()
&& !initializeParameter(o, method, -1, paramType, genericType)) {
return false;
}
Basically, if the wsdl states there is no output message (it's a one-way), then
the return type is irrelevant and should/could be completely skipped.
