Name matching fails with choice element
---------------------------------------
Key: AXIS2C-1373
URL: https://issues.apache.org/jira/browse/AXIS2C-1373
Project: Axis2-C
Issue Type: Bug
Components: code generation
Affects Versions: 1.6.0
Reporter: Aaron Oneal
Priority: Blocker
In testing against an Exchange server using EWS (Exchange Web Services), I have
discovered a blocking generated code issue.
Given this schema:
<xs:complexType name="ArrayOfResponseMessagesType">
<xs:choice maxOccurs="unbounded">
<xs:element name="CreateItemResponseMessage"
type="m:ItemInfoResponseMessageType"/>
<xs:element name="DeleteItemResponseMessage"
type="m:ResponseMessageType"/>
<xs:element name="GetItemResponseMessage"
type="m:ItemInfoResponseMessageType"/>
<xs:element name="UpdateItemResponseMessage"
type="m:UpdateItemResponseMessageType"/>
<xs:element name="SendItemResponseMessage" type="m:ResponseMessageType"/>
<xs:element name="DeleteFolderResponseMessage"
type="m:ResponseMessageType"/>
<xs:element name="CreateFolderResponseMessage"
type="m:FolderInfoResponseMessageType"/>
<xs:element name="GetFolderResponseMessage"
type="m:FolderInfoResponseMessageType"/>
<xs:element name="FindFolderResponseMessage"
type="m:FindFolderResponseMessageType"/>
<xs:element name="UpdateFolderResponseMessage"
type="m:FolderInfoResponseMessageType"/>
<xs:element name="MoveFolderResponseMessage"
type="m:FolderInfoResponseMessageType"/>
<xs:element name="CopyFolderResponseMessage"
type="m:FolderInfoResponseMessageType"/>
<xs:element name="CreateAttachmentResponseMessage"
type="m:AttachmentInfoResponseMessageType"/>
<xs:element name="DeleteAttachmentResponseMessage"
type="m:DeleteAttachmentResponseMessageType"/>
<xs:element name="GetAttachmentResponseMessage"
type="m:AttachmentInfoResponseMessageType"/>
<!-- Generic reponse to enumerating the items below a folder -->
<xs:element name="FindItemResponseMessage"
type="m:FindItemResponseMessageType"/>
<xs:element name="MoveItemResponseMessage"
type="m:ItemInfoResponseMessageType"/>
<xs:element name="CopyItemResponseMessage"
type="m:ItemInfoResponseMessageType"/>
<!-- ANR responses -->
<xs:element name="ResolveNamesResponseMessage"
type="m:ResolveNamesResponseMessageType"/>
<xs:element name="ExpandDLResponseMessage"
type="m:ExpandDLResponseMessageType"/>
<!-- Notification responses -->
<xs:element name="GetEventsResponseMessage"
type="m:GetEventsResponseMessageType"/>
<xs:element name="SubscribeResponseMessage"
type="m:SubscribeResponseMessageType"/>
<xs:element name="UnsubscribeResponseMessage"
type="m:ResponseMessageType"/>
<!-- Send Notification response -->
<xs:element name="SendNotificationResponseMessage"
type="m:SendNotificationResponseMessageType" />
<!-- Sync responses -->
<xs:element name="SyncFolderHierarchyResponseMessage"
type="m:SyncFolderHierarchyResponseMessageType"/>
<xs:element name="SyncFolderItemsResponseMessage"
type="m:SyncFolderItemsResponseMessageType"/>
<!-- Managed Folder responses -->
<xs:element name="CreateManagedFolderResponseMessage"
type="m:FolderInfoResponseMessageType"/>
<!-- ConvertId response-->
<xs:element name="ConvertIdResponseMessage"
type="m:ConvertIdResponseMessageType"/>
</xs:choice>
</xs:complexType>
Axis generates types:
ArrayOfResponseMessagesType
ArrayOfResponseMessagesTypeChoice
FindItemResponseMesage
...
A valid response message looks like this:
<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xmlns:xsd="http://www.w3.org/2001/XMLSchema";>
<soap:Header>
<t:ServerVersionInfo MajorVersion="8" MinorVersion="1"
MajorBuildNumber="375" MinorBuildNumber="1"
xmlns:t="http://schemas.microsoft.com/exchange/services/2006/types"; />
</soap:Header>
<soap:Body>
<m:FindItemResponse
xmlns:t="http://schemas.microsoft.com/exchange/services/2006/types";
xmlns:m="http://schemas.microsoft.com/exchange/services/2006/messages";>
<m:ResponseMessages>
<m:FindItemResponseMessage ResponseClass="Success">
<m:ResponseCode>NoError</m:ResponseCode>
<m:RootFolder TotalItemsInView="1" IncludesLastItemInRange="true">
<t:Items>
<t:Task>
<t:ItemId
Id="AAAQAGFvbmVhbEBhdmFsb24udXMARgAAAAAADubRCBB2Y068xYCH6WH0DgcAZ3A8uDQfUEKlwidoYrrErQAAAixOMgAArrJ7HqgcjEykQ1CwlhhwBQAAAiwIAQAA"
ChangeKey="EwAAABYAAABncDy4NB9QQqXCJ2hiusStAABdzMRd" />
</t:Task>
</t:Items>
</m:RootFolder>
</m:FindItemResponseMessage>
</m:ResponseMessages>
</m:FindItemResponse>
</soap:Body>
</soap:Envelope>
During deserialization of the ArrayOfResponseMessagesType, the first thing it
does is look for a qname of ArrayOfResponseMessagesTypeChoice, but what it
finds is a qname of FindItemResponseMessage (one of the choice types). The
qnames fail to match and so deserialization terminates.
I don't understand why it's looking for a "XXXChoice" qname when that's an
artificial type generated by Axis. The real type as specified in the WSDL is
what is returned in the response, so it's no surprise it doesn't match. Any
idea what's going on?
