Failed to compare two values....

This is the error i get when trying to use the action sortRecordList, in a string field....

Anyone knows how to fix this, or at list to find the corresponding values ?

Best regards,

I can't use the sorting widget here, since i'm building a list after a query so it would be great to hear some suggestions on how to sort a record list by a string value...

Thank you in advance,
