[ http://issues.apache.org/jira/browse/XALANJ-2325?page=comments#action_12442959 ] Brian Minchau commented on XALANJ-2325: ---------------------------------------
Per the JIRA triage meeting on Oct 16, 2005, Santiago P-G agreed to review the patch and see if it is robust. If the patch is not good then it will probably not be re-worked. > XSLTC Causes NoSuchFieldError if global variable is unused > ---------------------------------------------------------- > > Key: XALANJ-2325 > URL: http://issues.apache.org/jira/browse/XALANJ-2325 > Project: XalanJ2 > Issue Type: Bug > Components: XSLTC > Affects Versions: 2.7 > Environment: Windows 2003, JRE 1.4. > Reporter: Fred Kruesi > Attachments: TestXsl.zip, variable.patch > > > If one has a style sheet that imports other style sheets which further > include other style sheets and the last imported style sheet does not use a > global variable it declared, XSLTC discards the variable even though it is > used by other sheets. This leads to a NoSuchFieldError when the sheet is > used. Following is a schematic view of the sheets. The actual sheets are in a > test case. > foo.xsl: > <xsl:import href="imported/import1.xsl"/> > <xsl:import href="imported/import2.xsl"/> > <xsl:template match="bar:element"> > Value of info: <xsl:value-of select="info"/> > Value of my-var from import: <xsl:call-template name="import1.xsl"/> > Value of my-var from import: <xsl:call-template name="import2.xsl"/> > </xsl:template> > imported/import1.xsl: > <xsl:include href="../inc1/inc1a.xsl"/> > > <xsl:template name="import1.xsl"> > From import1 my-var: <xsl:value-of select="$my-var"/> > </xsl:template> > imported/import2.xsl: > <xsl:include href="../inc1/inc1a.xsl"/> > > <xsl:template name="import2.xsl"> > From import2 my-var: > </xsl:template> > ../inc1/inc1a.xsl > <xsl:variable name="my-var"> > <Data code="Y"> > <Desc>Yes</Desc> > </Data> > <Data code="N"> > <Desc>No</Desc> > </Data> > </xsl:variable> > Note that imported/import2 does declares, but does not use "my-var".
