[mashup-dev] [jira] Commented: (MASHUP-16) Functions returning an XMLList of one XML node fail.

    [ http://www.wso2.org/jira/browse/MASHUP-16?page=comments#action_10792 ] 
            
Jonathan Marsh commented on MASHUP-16:
--------------------------------------

Huh?  The operation can't be in-only if it has a return statement!  Let me provide some more detail.

A service with three operations as follows:

function xmlnode(payload) {
   return <successful/>;
}

function xmlnodelist(payload) {
   return <><successful/></>;
}

function xmlnodelist2(payload) {
   return <><successful/><excess/></>;
}

Each of these is represented as an in-out operation in the generated WSDL.  (We don't support anything except in-out operations at this point.)

The first operation can be invoked successfully, the second two can't.  While I don't know what to do about the third yet (an automatic wrapper? a wrapper derived from analizing the annotation?), this bug is about the second - where in E4X an XML node and an XML node list with a single item are treated identically.  This bug is about that middle case - the first two operations should operate identically from the client perspective.

> Not sure what the desired behavior is here, esp. if there are multiple nodes in the node list, but it seems unfortunate to send a fault for an XMLList of zero or one item.
