Description

As integration with Legacy Stack requires that all Field Types are also = also handled on 5.x stack side, Null Field Type is provided as a dummy for = legacy Field Types that are not really implemented on 5.x side.

Null Field Type will accept anything provided as a value, but will not s= tore anything to the database, nor will it read any data from the database.=

This Field Type does not have its own fixed internal name. Its identifie= r is instead configured as needed by passing it as an argument to the const= ructor.

Following example shows how Null Field Type is used to configure dummy i= mplementations for ezcomcomments and ezpaex legac= y datatypes:
