Application not working on EHP7
I have a query regarding one of the applications functionality. We have the sandbox portal running on EHP5 and Dev Portal running on EHP7.
There is an application which runs fine on Sandbox Portal but the same application doesn't work on Dev Portal even when the application parameters and system aliases are set properly. The application flow/navigation is not happening under EHP7.
Could anyone pls let me know what could be the proper resolution to this.
