Classic Servoy

I’m trying to use the webclient, but when i try to create a new record, show me some errors:

MSG: TypeError: Cannot read property "vEditOnTab" from undefined (/Applications/Servoys/Servoy_QCinst_nuevo/workspace/svy_nav_navigation/forms/svy_nav_base.js#1965)

And when i access to the new record, can’t put anything new, and can’t save/cancel. Show the record in the dtl but with the data of the selected record.
