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

Hi,

I am new to umbraco and working on media files and getting some problems.Please have a look at them and tell me where i am wrong.

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE xsl:stylesheet [ <!ENTITY nbsp " "> ]>
<xsl:stylesheet
  version="1.0"
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
  xmlns:msxml="urn:schemas-microsoft-com:xslt"
  xmlns:umbraco.library="urn:umbraco.library" xmlns:Exslt.ExsltCommon="urn:Exslt.ExsltCommon" xmlns:Exslt.ExsltDatesAndTimes="urn:Exslt.ExsltDatesAndTimes" xmlns:Exslt.ExsltMath="urn:Exslt.ExsltMath" xmlns:Exslt.ExsltRegularExpressions="urn:Exslt.ExsltRegularExpressions" xmlns:Exslt.ExsltStrings="urn:Exslt.ExsltStrings" xmlns:Exslt.ExsltSets="urn:Exslt.ExsltSets"
  exclude-result-prefixes="msxml umbraco.library Exslt.ExsltCommon Exslt.ExsltDatesAndTimes Exslt.ExsltMath Exslt.ExsltRegularExpressions Exslt.ExsltStrings Exslt.ExsltSets ">

<xsl:output method="xml" omit-xml-declaration="yes"/>

<xsl:param name="currentPage"/>

<xsl:template match="/">


  <xsl:value-of select="$currentPage/mediaItem"/>   // Its returning 1052

<xsl:value-of select="umbraco.library:GetMedia($currentPage/mediaItem, 'false')"/>
// Here is the error.
</xsl:template>

</xsl:stylesheet>

When i use <xsl:value-of select="umbraco.library:GetMedia($currentPage/mediaItem, 'false')"/>

then its throwing error

Error occured

If i use <xsl:value-of select="umbraco.library:GetMedia(1052, 'false')"/>

Then its perfect.Please tell me whats wrong in the above code.

Thanks

Hi,

You should wrap the GetMedia calls in a check to verify you have a value. The reason is that when you press Save, Umbraco does a quick test of your XSLT file. In this test it may not have a value for $currentPage/mediaItem - and this will cause an exception as GetMedia is expecting an integer. Also this could happen if you run the macro on a page that doesn't have any media selected.

So you can handle both situations by wrapping it in a test to ensure there is a value:
```
<xsl:variable name="mediaId" select="$currentPage/mediaItem"/>

<xsl:if test="$mediaId &gt; 0">
  <xsl:value-of select="umbraco.library:GetMedia($mediaId, false())"/>
</xsl:if>
```
Hope this helps,
Tom
