the scripts work fine, many thanks again!
May I just ask you one more question?
Is there the possibility to remove a feature from a list of features? like
featureslist.remove() or something like that?
I tried with remove and delete but it seems that these do not exist, any
Is there a way to know which functions are implemented for each feature
type in gvSIG scripting?
