nadir amra commented on AXISCPP-978:
------------------------------------
I am going to resolve the issue as described above, i.e. inserting "m_pNode =
NULL" in all 3 occurrences. Also, somewhat related to nodes not being handled
correctly, if a complex type defined as:
<s:complexType name="SortR">
<s:sequence>
<s:element minOccurs="0" maxOccurs="1" name="ListMsg"
type="tns:ArrayOfMsgS" />
<s:element minOccurs="0" maxOccurs="1" name="DateMed" type="s:string"
/>
<s:element minOccurs="1" maxOccurs="1" name="NumberMed" type="s:int"
/>
</s:sequence>
</s:complexType>
And the response comes back as:
<SortRResult>
<ListMsg/>
<DateMed>2006-11-10</DateMed>
<NumberMed>123456</NumberMed>
.
.
The deserialization of ListMsg does not recognize the fact that empty element
was passed and thus attempts to parse the subsequent data as if it was part of
ListMsg. I have added code in
SoapDeSerializer::getCmplxObject() so that it now looks like the following (the
else part is new):
if (0 != m_pNode->m_pchAttributes[0]) { ... }
else
{
// AXISCPP-978
// If the node represents a START_END_ELEMENT, then simply
return
if (START_END_ELEMENT == m_pNode->m_type2)
{
m_pNode = NULL; /* node identified and used */
return NULL;
}
}
Please let me know if there is a problem with this.

> URL: http://issues.apache.org/jira/browse/AXISCPP-978
> Project: Axis-C++
> Issue Type: Bug
> Components: Client - Deserialization
> Affects Versions: current (nightly)
> Environment: WIN2KSP4 MSVC6SP6 JDK 1.5.0_07 XercesC 2.7.0
> Reporter: Franz Fehringer
> Assigned To: nadir amra
> Attachments: pegs.wsdl, pegs.xsd, t_RoomRate2.cpp, t_SellRate.cpp,
> vaw.xml
>
>
> With AxisC++ (current SVN plus XercesC 2.7.0 on WIN2KSP4/JDK5/VC6SP6) i have
> a severe problem, namely that my response message is not parsed correctly.
> With the fragment (whole xml response appended)
> <pgs:RequiredRoom exactMatch="true" adults="1" children="1" cots="1"
> extraAdultBeds="1" extraChildBeds="1">SINGLE</pgs:RequiredRoom>
> <pgs:SellRate currencyCode="USD" inclusiveOfTax="false"
> commission="5">70</pgs:SellRate>
> in the first line the AxisC XercesC wrapper advances (using next()) from
> START_ELEMENT to CHARACTER_ELEMENT after having read all attributes and
> therefore correctly detects "SINGLE".
> But in the second line after having read all attributes, next() does not
> advance to CHARACTER_ELEMENT, but stays on START_ELEMENT, which means that
> "70" cannot be read (and the whole following xml block is disregarded too).
> It seems, that in the second line the AxisC++ deserializing code thinks that
> there is something left, which has to be handled prior to advancing to the
> CHARACTER_ELEMENT.
> We had some debug sessions and our first guess is, that there is something
> wrong with deserializing arrays/lists/sequences (which are nested in this
> case; maybe the problem?).
> A second (to our opinion less probable) guess is, that the AxisC deserializer
> thinks, that there could be remaining attributes.
> What can be observed is, that in the first (successful) case m_bPeeked is
> false, whereas in the second (error) case m_bPeeked is true.
