[Erp5-dev] Sorting listboxes' columns using 'integer' sort

[Mikolaj Antoszkiewicz]

I know it is possible to make portal_catalog sort the data it retrieves by the 
integer field, by forcing 'int' conversion of the sorted field.

Is it possible to make listbox do the same, i.e. sort by numerical ID in '1 2 
3 4 10' fashion rather than '1 10 2 3 30' ? And how that can be achieved?
Is it something to do with Default Sort property?

P.S. The List Method is a custom script not a portal_catalog/searchFolder...
