[Zope] dtml-in sort_expr and expression

[Jaroslav Lukesh]

Dear all,

I have problem with sorting by values. I have numbers in database in 
textual form.

I need something like

<dtml-in database sort=a,b>

this sorting is bad becaouse a and b are strings, not numbers. But 
following examples

<dtml-in database sort_expr="int(a),int(b)">
<dtml-in database sort_expr="_str(a).int(),_str(b).int()">

returns errors for all what I was try.

Many thanks for help,
