Webdynpro ABAP in Portal (Caching Problem)

Hi all,

We are running on NW 7.0 SP 12 as dual stack with ABAP system and NetWeaver Portal Usage Type 7.0 SP 12.

I want to display a Webdynpro ABAP application in portal which is developed in an runs on ABAP stack.

I have an created an application in the backend with the following parameters :

Webdynpro Component name:   TESTWEBDYNPRO

Webdynpro Application name :- ztestwebdynpro

I created the Webdynpro ABAP iview with following parameters :

Application name :- ztestwebdynpro

Namespace :- sap

System :- SAP_WD4A_System

Cache-Level: none

Client site Caching: No

Launch in New Window:  Display in Portal Content Area

If I open Iview in first time everything works fine, but if I reload the iview nothing changes (means that the state of WebDynpro is cached ): values from former application call are still set in UI controls or state of roadmap control is not initial.

Any hints to solve this behaviour?

Thanks,

Marc
