I have a series of records - each is then replicated multiple times by date and then have andother column with either a value or null. each also has a unidue key based on the geom.

not every date has a value and thus in null.

what i need to search for is for each unique geom find the record that has the latest date with a value in the extra field.

needs to return one record per unique id

any help appreciated

Tester to test for the existance of the value. Sorter to sort on date. Sampler to sample the first. Or a matcher, or duplicateFilter.
