My first application was developed in apex 4.2 when apex 5.1 had been released I created a new application and copied pages from the previous application which was apex 4.2.
I am currently using that application which being upgraded to the last version apex 21.1.
I add dynamic action in an interactive grid column, it works fine in the development environment. if I used the application in the production environment the dynamic action not firing at all.
if I created a new application and add the dynamic action everything works fine in the development or production.
My application is hosted at a company hosting apex.
