Content Picker

Hi folks,

I have a content picker alias in "discoverUrl" and seems like my xslt wont save and returning me errors whenever i dont choose any content.

Here is my xslt, not sure what am doing wrong here

<ul>
      <xsl:for-each select="$currentPage">       
        <xsl:variable name="discover" select="discoverURL" />         
        <xsl:if test="string($discover) != ' '">
            <xsl:variable name="sUrl" select="umbraco.library:NiceUrl(discoverURL)"/>
            <xsl:value-of select="$sUrl"/>
        </xsl:if>    
      </xsl:for-each>
  </ul>

Any idea ?

Hi Fuji,

Problem is if it's empty, it will be different from ' ' so the NiceUrl() is called.

Use normalize-space() instead:
```
<xsl:if test="normalize-space($discover)">
...
</xsl:if>
```
