Subject [jira] Commented: (AXISCPP-978) deserializing of arrays of complex types with optional elements broken
Date Wed, 28 Jun 2006 15:55:30 GMT
    [ http://issues.apache.org/jira/browse/AXISCPP-978?page=comments#action_12418269 ] 

Franz Fehringer commented on AXISCPP-978:
-----------------------------------------

I think i have found one problem.
In SoapDeSerializer::getCmplxObject (SoapDeserializer.cpp) after having read the wanted item
line 865 says
m_pParser->next ();    /* skip end node too */
With this statement the parsing advances from (CHARACTER_ELEMENT,END_ELEMENT) to (END_ELEMENT,END_ELEMENT).
What is missing to my opinion and what i successfully put in is
m_pNode = NULL;    /* node identified and used */
after this line.
Without this line, m_pNode stays on (END_ELEMENT,END_ELEMENT) and on the next call of SoapDeSerializer::getCmplxObject
does not advance further in the lines 818, 819 saying
if (!m_pNode)
    m_pNode = m_pParser->next ();

>      Project: Axis-C++
>         Type: Bug

>   Components: Client - Deserialization
>     Versions: current (nightly)
>  Environment: WIN2KSP4 MSVC6SP6 JDK 1.5.0_07 XercesC 2.7.0
>     Reporter: Franz Fehringer
>  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.
