Problem

Error received while resizing route using toolbar, ORA-01422 unhandled exception. He tried to change the survey length for a route and then tried resizing

Solution

1. This error occurs because there were lot of duplicate geometry data for those sections, to fix this you must delete those duplicate records in GEOMETRY_TABLE
2. A better way is to see if a unique constraint is imposed on similar tables
