    Passing variable to GetMedia causes error

    Hey,

    I have some strange issues with umbrac.library.GetMedia. Consider the  example blow.
    I have a property called storeIcon which has data type Media Picker. When I store this property in a variable and output the variable the value 1254 is printed. When I pass this variable into the GetMedia method the xslt crash with error System.OverflowException: Value was either too large or too small for an Int32. When I hard code its value (as the example shows below) the image is rendered. What am I doing wrong here?

    <xsl:for-each select="current()/* [name() = $recordStoreTypeAlias]">
                <xsl:variable name="storeIcon" select="number(storeIcon)" />
                <xsl:value-of select="$storeIcon"/>
                <xsl:variable name="thumbnail" select="umbraco.library:GetMedia($storeIcon, 0)" />   <--This row generates the error
                <xsl:variable name="thumbnail" select="umbraco.library:GetMedia('1254', 0)" />   <-- This row works
                <img src="{$thumbnail/umbracoFile}" />
              </xsl:for-each>

    Hey,

    If you add a check like this your problem will go away.

     

    <xsl:for-each select="current()/* [name() = $recordStoreTypeAlias]">

                <xsl:variable name="storeIcon" select="number(storeIcon)" />

                <xsl:value-of select="$storeIcon"/>

     

    <xsl:if test="$storeIcon != '' ">

                <xsl:variable name="thumbnail" select="umbraco.library:GetMedia($storeIcon, 0)" />   <--This row generates the error

    </xsl:if>

                <xsl:variable name="thumbnail" select="umbraco.library:GetMedia('1254', 0)" />   <-- This row works

                <img src="{$thumbnail/umbracoFile}" />

              </xsl:for-each>

    Sorry!

    Should be

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

    Rich :)

    Got it working now!

    Instead of using a variable I check the storeIcon property directly in the if-statement and then use it in the GetMedia method if it is not empty.
