    Error when getting media images

     

    Hi All,

    I am trying to get all the Media images and then get the data alias company name and match that to a variable. But I am failing at the first hurdle, I cant even get all the images which reside in the media section

    This my current code

      <xsl:template match="/">
        <xsl:for-each select="umbraco.library:GetMedia(./data [@nodeTypeAlias = 'Image'],'false')/data">
          
        </xsl:for-each>
      </xsl:template>

    This is the error I am getting

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

    Any help greatly appreciated

    Thanks

    Tom

    Tom,

    Do you get the error when saving the xslt? If so, it's due to the fact that your for-each does not necessarily hold a value (xslt's are checked against a node when saving - but it's not garantueed that node  - think it's the top level node - has a value for that property)

    Anyway, it's best practise to surround with an xsl:if statement to avoid the runtime error.

    <xsl:if test="string-length(./data [@alias = 'Image']) &gt; 0">
  <!-- your for-each code -->
</xsl:if>

    Hope this helps.

    Regards,

    /Dirk
