I’m testing the migration of an APEX application
Old Environment. Donor Environment
Oracle Database 12c Standard Edition Release 12.1.0.2.0 - 64bit Production
APEX 19.1.0.00.15
ORDS 18.4.0.365
New Environment. Destination Environment
Oracle Database 19c Enterprise Edition Release 19.0.0.0.0 – Production Version 19.3.0.0.0
APEX 21.1.0
ORDS 21.1.3.r1531102
The application was build years ago in previous versions of APEX ( 4.x ) and was running without problems in the “Donor Environment”.
The New Environment (APEX Developer Environment and APEX INTERNAL Workspace Environment) runs perfect apparently. I’ve been able of import workspace and application from the Donor Environment without Errors.
There are pages build with old Ext JS extensions sited in external files in the Application Server.
I’ve located two problems but I’m afraid I’m stuck.
PROBLEM 1:
I’m facing problems with messages like
Uncaught TypeError: Cannot set property 'value' of null
in case of code like
document.getElementById('P1011_RESOLUCION').value
PROBLEM 2:
Problems with messages like
Refused to execute script from …… because its MIME type ('text/plain') is not executable, and strict MIME type checking is enabled.
The involved pages with these problems are shown but some content is removed (not shown on the page).
Regards.
Any help or idea is welcome.
Thanks in advance.
