[HippoCMS-dev] Numeric DASL:orderby after extractor

[Ewald Ramp]

Hello,

I have a problem with sorting a DASL query on an metadata field that I
obtained by an extractor. The intention is that the extractor calculates
a numeric value, and then the d:orderby should order on that value.
However, I end up with a alphabetic ordering instead of a numeric one
(with ascending, I get 100 before 2). What do I need to do to use a
numeric sorting (to evaluate the values as numbers?)

The relevant code in my extractor looks like:

<instruction property="courseDuration"
namespace="http://hippo.nl/cms/1.0";
xpath="/document/content/data/opleiding.duur*365"/>

And in my DASL Query:

<d:orderby>
  <d:order>
    <d:prop>
      <h:courseDuration/>
    </d:prop>      
    <d:ascending/>
  </d:order>
</d:orderby>

Thanks for your help,

Ewald
