Session-Handling / Lifecycle management / Instances of application class

Hi there,

I'm developping a BSP-Application that inherits also other applications(text-pages) that can be started from the main-app in to a separate window.

when I open such a sub-application and close the window again (close sub-app), the main-app saves the state of the sub-app (navigation-information). altough im starting a new session(sap-sessioncmd=open in url)they use the same instance of the application class.

I thought every session gets it's own instance of application class. is this wrong?

can anybody help me?

thanks,

frank
