Hi neil,

Is that at design-time? If so, then yes, this error should occur cause it is being verified against a top node which might not have that property. A solution is to surround the xsl:value-of with a xsl:if statement.

Hope this helps.

That makes sense.

Thanks for you help!

Hi,

I am having a similar issue (Int32) in Umbraco 4.5 using new XML format and would appreciate any tips:

I see the correct value of $thumb which is the NodeID from the data picker so I assume I have the right variable, and if I put a NodeID in place of $thumb it returns the image.

Any thoughts?

Thanks,

Chris

    <xsl:for-each select="$currentPage/* [@isDoc]">
      
        <xsl:variable name="thumb" select="stillthumb"/>
      
        <xsl:value-of select="$thumb"/>        

<xsl:variable name="thumbnail" select="umbraco.library:GetMedia($thumb, 0)" /> 
         
    <img src="{$thumbnail/Image/umbracoFile}" alt="@nodeName" style="height: 158px; width: 280px;" /></a>
                 
    </xsl:for-each>

Have you tried converting the value in $thumb explicitly to a number, like

<xsl:variable name="thumb" select="number(stillthumb)" />?

The problem is in the way you call GetMedia. Once $thumb does not contain an int (or it can't yet determined if it will ever contain an int), you get this error.

I would do something like this (and yes, converting to a number is a great idea!):

<xsl:if test="number($thumb) &gt; 0">
  <xsl:variable name="thumbnail" select="umbraco.library:GetMedia(number($thumb), 0)" /> 
</xsl:if>  

Hi,

Thank you both for your suggestions - I had already tried them previously to no effect. However I've implemented the casting and the if-test again; and now I'm seeing a different error:

With a value-of in the if condition, I'm seeing the nodeID's.

Thanks again,

Chris
