I've found yet another bug in my powerfind class. I have been pondering for quite some time and had no luck with it. Maybe some of you guys that are using it could take a look and see if you can help me spot it.

Perform a search on any field.
Then double click on one of the grid headers, this will order the column
Then try to perform another search.

the last search will return an empty data set regardless.

The column sort is creating a problem, but only after a search. If you sort the column first then do the search it works fine.

see zsearch and zsortcolumn methods.
