Konstantin Pribluda updated AXIS2-4222:
---------------------------------------
Attachment: axis-4222.patch
ChiceTest will loop forever, unless ADBBeanTemplate.xsl
has been patched ( sorry for brevity, my wife is about
to throh me out of home and cut internet ;) )
> Codegen introduces infinite loop in generated code ( while deserealising )
> ---------------------------------------------------------------------------
>
> Key: AXIS2-4222
> URL: https://issues.apache.org/jira/browse/AXIS2-4222
> Project: Axis 2.0 (Axis2)
> Issue Type: Bug
> Components: codegen
> Affects Versions: 1.5
> Environment: current codebase from svn
> Reporter: Konstantin Pribluda
> Attachments: axis-4222.patch
>
>
> I have following complex type:
> ---------------- snip -------------
> <xs:complexType name="typePRODUCTLINK">
> <xs:sequence>
> <xs:choice>
> <xs:element ref="P_ID"/>
> <xs:element ref="P_NVAG_PID"/>
> </xs:choice>
> <xs:element name="LINK_SORT" minOccurs="0">
> <xs:annotation>
>
> <xs:documentation>(Sortierung)</xs:documentation>
> </xs:annotation>
> <xs:simpleType>
> <xs:restriction base="typeSORT">
> <xs:totalDigits value="3"/>
> </xs:restriction>
> </xs:simpleType>
> </xs:element>
> </xs:sequence>
> </xs:complexType>
> -------------------- snap ----------------------
> And it produces following while loop:
> ------------------------ snip ---------------
> while(!reader.isEndElement()) {
> if (reader.isStartElement() ){
>
> if (reader.isStartElement() ){
>
>
> object.setTypePRODUCTLINKChoice_type0(censored.TypePRODUCTLINKChoice_type0.Factory.parse(reader));
>
> } // End of if for expected property start
> element
>
> else
>
> if (reader.isStartElement() && new
> javax.xml.namespace.QName("censored","LINK_SORT").equals(reader.getName())){
>
>
> object.setLINK_SORT(censored.LINK_SORT_type1.Factory.parse(reader));
>
> reader.next();
>
> } // End of if for expected property start
> element
>
> } else {
> reader.next();
> }
> } // end of while loop
> --------------------- snap -----------------
> This is obvious, that this while loop never goes for LINK_SORT, and thus
> never terminates
> for such XML snippet:
> ------------------- snip -----------------
> <P_SUBPRODUCT type="FAMILY">
> <P_ID>402322g</P_ID>
> <LINK_SORT>1</LINK_SORT>
> </P_SUBPRODUCT>
> ------------------- snap ----------------
> I was able to identify problem source in ADBBeanTemplateXSL ( from line 2816
> ):
> -----------------snip----------
> <xsl:choose>
> <xsl:when test="$unordered and not($choice
> and $hasParticleType)"> <!-- One property per iteration if unordered -->
> <xsl:if test="position()>1">
> else
> </xsl:if>
> </xsl:when>
> <xsl:otherwise>
> <!-- If sequence, advance to start of
> next property or to end of outer element -->
> while (!reader.isStartElement()
> && !reader.isEndElement()) reader.next();
> </xsl:otherwise>
> </xsl:choose>
> -----------------snap---------
> If I manually edit generated beans as if "otherwise" was choosen, everything
> works as expected.
> So IMHO bug is somewhere in choice condition. ( but unfortunately my limited
> experience with codegen codebase does not allow me to produce a patch at the
> moment,
> though it may change really soon )
