exf:sort bug

Alex / Erik,

I'm trying to use exf:sort to sort an itemset in my select1 .... if I
use ...

<xforms:itemset nodeset="instance('geographicOrg')//node[not(node/id)]">
<exf:sort select="name"/>
<xforms:label ref="name"/>
<xforms:value ref="id"/>
</xforms:itemset>

I get no errors but it also doesn't sort on name. If I try ....

<xforms:itemset
nodeset="exf:sort(instance('geographicOrg')//node[not(node/id)], 'name')">
<xforms:label ref="name"/>
<xforms:value ref="id"/>
</xforms:itemset>

I get this error ..... XForms error: Non-comparable types found while
sorting: Objects are not comparable (class
org.orbeon.saxon.dom4j.NodeWrapper, class
org.orbeon.saxon.dom4j.NodeWrapper)

Is this a bug??

Steve

Re: exf:sort bug

Steve, according to Erik's response to my question:

http://www.objectweb.org/wws/arc/ops-users/2006-12/msg00185.html

...seems like you will have to use the "function variant" of the sort
functionality as the "element variant" is not supported by OF.

Re: exf:sort bug

Alex,

Thanks, that answers why it is working that way, but I still get the error below when I try to use the "function variant".

Re: exf:sort bug

Steve,

It took me a while to figure out how to populate the function params to make it work. It is possible that I have also encountered the error you are seeing, but I do not remember any more. I assume you are using one of the newer OF builds that support the function?

This is the sorting snippet from my code that is working:

<xforms:repeat nodeset="exf:sort(//row, concat('item[',//app/sorting,']/v'), //app/sorting/@data-type, //app/sorting/@order)" id="row">

If you want I can send you the complete XHTML file.

Alex,

Thanks, I got it working now. I added 'text' to the sort function ...... not sure why this is needed, its supposed to be optional and default to 'text' but apparently it's not.
