    how to convert umbraco.library:RenderTemplate parameter to int32

    umbraco 4.0.3 IIS6 W2K3R2 .net 3.5 sp1

    Hi, on an xslt template I'm trying to supply umbraco.library:RenderTemplate with /macro/bannerNodeId (as per method signature). The macro parameter is defined as a number. Not sure what's wrong with this (see exception below when trying to save xslt). I also tried to passing an xml node as parameter, then assign /macro/xmlNode/@id to bannerNodeId, no luck either. Any help really appreciated :-)

    <xsl:template match="/">

    <xsl:variable name="bannerNodeId" select="/macro/bannerNodeId"/>

    <xsl:value-of select="umbraco.library:RenderTemplate($bannerNodeId)" disable-output-escaping="yes"/>
    </xsl:template>

    exception stack:

    System.OverflowException: Value was either too large or too small for an Int32.

    Hi Eduardo,
    What you are doing is fine, you just need to wrap an if statement around the value-of statement to check that $bannerNodeId is not empty.

    So it should be:

    <xsl:template match="/">

    <xsl:variable name="bannerNodeId" select="/macro/bannerNodeId"/>

    <xsl:if test="$bannerNodeId != ''">
       <xsl:value-of select="umbraco.library:RenderTemplate($bannerNodeId)" disable-output-escaping="yes"/>
    </xsl:if>

    </xsl:template>

    Hope this helps

    Cheers,
    Neil
