Form compiling problem during testing of Family Patch G

After patching and upgrading a copy of our production environment, I attempted to compile (generate) a custom form (based off of TEMPLATE.fmb). 
The following error happens:
>>>>>>>>>>>>>>>>>>>>>>>

Compiling package body APP_CUSTOM...
Compilation error on package body APP_CUSTOM:
PL/SQL ERROR 302 at line 22, column 19
component 'DISABLED' must be declared
PL/SQL ERROR 0 at line 22, column 5

PL/SQL ERROR 201 at line 40, column 5
identifier 'APP_WINDOW.CLOSE_FIRST_WINDOW' must be declared
PL/SQL ERROR 0 at line 40, column 5
Statement ignored

Compilation errors have occurred.

Form not created

I've tried compiling the TEMPLATE.fmb file and get the same error.
