Description

I hope that I am right that I have found a bug in the runtime of Saxon-JS-beta-0.9.1.1. I have an xsl:choose, the first test compares a string parameter with a string literal. Although the parameter can hardly be anything else but an xs:string (also by the as= clause of its definition), I get the error "Supplied value "..." is not a valid xs:base64" in the javascript console of Firefox and Chrome. If I cast the parameter by wrapping it in xs:string(), the error remains. But if I concat an empty string before doing the compare, all goes well, even when the parameter value matches another xsl:when inside the same xsl:choose-stanza.

Maybe useful to remark that part of its life time, the parameter is a tunnel parameter.

You can watch the working version at http://www.masereeuw.nl/tangram. I'll be happy to supply source code if that helps.

Here is an abbridged snipped of my code:

@<xsl:template name="do-next-figure">

    <xsl:param name="next-figure" as="xs:string" required="yes"/>

    
    <xsl:choose>

        <!-- Intended line was:

            
            <xsl:when test="$next-figure eq 'transparant-tangram'">

            
            but for some reason this fails with an error in the Javascript console:

            XError: Supplied value "sitting-cat" is not a valid xs:base64 at file:/home/pieter/saxonjs-experimenten/tangram/tangram4saxonjs.xslt#227

            
            When we change the test as shown (concatening an empty string, then compare), all goes well, even if the other comparable tests are

            left as they are.

        -->

        <xsl:when test="concat($next-figure, '') eq 'transparant-tangram'">

            <xsl:call-template name="do-transparant-tangram">

                <xsl:with-param name="transforms" select="$tangram-transforms"/>

            </xsl:call-template>

        </xsl:when>

        
        <xsl:when test="$next-figure eq 'blue-tangram'">

            <xsl:call-template name="do-blue-tangram">

                <xsl:with-param name="transforms" select="$tangram-transforms"/>

            </xsl:call-template>

        </xsl:when>
        <xsl:otherwise>

            <xsl:message>Don't know how to deal with figure "<xsl:value-of select="$next-figure"/>".</xsl:message>

        </xsl:otherwise>

    </xsl:choose>

</xsl:template>@
