Re: How to save shp & dbf from an EsriPlugin?

Yes, this solves the problem.

I've now also, succeeded in doing it throught jdbc/sql statements, thats
makes the whole thing more efficient when only a few changes are made
into the database. It would be nice to add a kind of "void
SetSaveMasterDbf(boolean b)" member to EsriShapeExport that let the user
decide himsel if he wants or not save the .dbf file.

In a next OpenMap release perhaps?

b.
