We are doing mashup between pega application

Application A is running in pega version 8.2.1 and application B is running in version 7.2.1

Through Mashup we are trying to display Application A in Application B

Issue we are facing

1. Screen is not refreshing and buttons in mashup screen is not working
2. Portal display only first time, when launch second time from application B, it is not loading
3. Pega 8.2.1 pzIncludeMashupScripts generates error when try to call in pega 7.2.1 application
