[Gvsig_english] Find duplicates

[Wolfgang Qual]

Hi list,
I remember ArcView 3.2 having an extension to look for duplicates in an 
attribute table. This can be handy, if you would like to make sure that you 
have a unique-value-column (which should be later used as the ID-column for a 
join, etc.). Question therefore: is it already possible in gvSIG to perform 
such a search or: do developers think of something like this? Could be really 
handy ;)

Greetings,
Wolfgang
