6160 Invalid type cast

Cause

This error occurs if the input contains a typecast that is not valid. This can be for one of the following reasons.

The code attempts to cast a class to a primitive type or a primitive type to a class.
An illegal primitive typecast is being performed (for a complete list of valid and invalid primitive type casts, see "Type Casts", in Chapter 1 of the JADE Developer’s Reference).

An illegal class type cast is being performed.

For a typecast to be legal, the class of the typecast must be the same as, or a subclass of, the defined class of the operand; for example, if f is defined to be of class Form:

base   := f.MyBaseForm // valid
                       // MyBaseForm is a subclass of Form
win    := f.Window     // invalid
                       // Window is not a subclass of Form
button := f.Button     // invalid
                       // Button is not a subclass of Form

Action

Change the typecast so that it conforms to the above rules.
