xsltc throws exception when xsl:choose condition is evaluated
Hi All,
I have a template call as shown below to find out access_level. This
variable should be assigned to 3 after the template call returns. but
instead it throws runtime exception in translet while transformation. I
am unable understand the reason for failure.This works just fine with
interpretive processor.Please help. cut short version of xsl is
included.
Actual files which I am working are attached for transformations use.
<xsl:variable name="access_level"><xsl:call-template

and the template getAccessLevel is written in specifics.xsl file which
is included in caller xsl.
<xsl:template name="getAccessLevel">
<xsl:param name="AccLevel"/>
<xsl:param name="Port"/>
<xsl:choose>
<xsl:when test="$Port = 'UI'"><xsl:value-of

</xsl:when>

</xsl:when>
<xsl:when test="$AccLevel = $TL1_READ-ONLY">

</xsl:when>
<xsl:when test="$AccLevel = $TL1_NONE">
<xsl:value-of select="$NONE"/>
</xsl:when>
</xsl:choose>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
your help would be highly appreciated.
Thanks in advance,

I don't think anybody ever responded to you. This appears to be the
same problem, with a different symptom described by Jira issue
XALANJ-1742.[1]
There is a reference to getAccessLevel inside the definition of the
"access_level" global variable (in configRackNew.xsl), and getAccessLevel
contains references to the global variables "TL1_ADMIN," "TL1_READ-WRITE,"
"TL1_READ-ONLY," and "TL1_NONE." However, XSLTC is generating code that
defines the access_level variable before the code that defines the values
of those TL1_* variables. The result is a NullPointerException for any of
those undefined variables.
The work-around is to modify your stylesheet to take into account
dependencies between global variables. If GV2 uses the value of GV1,
place the definition of GV1 closer to the start of the document than GV2
(or give it higher import precedence).
I hope that helps. If you feel that work-around is not acceptable,
please feel free to add a comment to the Jira issue.
Thanks,
Henry
