[Biojava-l] update seqfeature

[Martina]

Hi Simon,

I'm changing the FeatureSource and in setFeatureSource an update on 
the source_term_id happens. In the case the combination is already 
there, I get an Exception. The proper way to deal with that would be 
to get the seqfeature_id of the entry already there and use that, or 
try to update the rank unless its a unique combination? Or should I 
rather not mess with the BioJava and delete that entry and insert it 
as new to let BioJava handle the rank increase?

Thanks for any advise
