Incorrectly removing a parameter from the Message

I've been having the following issue for a whole day already, and I'm debugging it: http://www.coderanch.com/t/466933/Web-Services/java/CXF-fails-serve-WebService

I've got further ahead:

in WrapperClassInInterceptor there is this code:

(line 135 onwards)

newParams = new MessageContentsList(helper.getWrapperParts(wrappedObject));

List<Integer> removes = null;
int count = 0;
for (MessagePartInfo part : messageInfo.getMessageParts()) {
if (Boolean.TRUE.equals(part.getProperty("messagepart.isheader"))) {
MessagePartInfo mpi = wrappedMessageInfo.getMessagePart(part
.getName());
if (lst.hasValue(mpi))

{ newParams.put(part, lst.get(mpi)); }

else if (mpi.getTypeClass() == null) {
if (removes == null)

{ removes = new ArrayList(); }

removes.add(Integer.valueOf(mpi.getIndex()));
}
} else

{ ++count; }

}

The parameters in "newParams" before the removes are removed are the correct params + one null at the end.
Then index "1" is removed. BUT the param at Index 1 is correct. So perhaps the index is wrongly calculated. I don't have any more time to dig further into the generation of the index, so I'm just patching my version by commenting-out the removal part. I hope you can give me an update no this. Thanks
