I'm developing a web dynpro component with CAF GP interface as Callable Object. All is running fine, I can design a process with my component and run it and the web dynpro ui is shown correctly. But I'm not able to create Messages using the MessageManager api.
In my Init method i get an instace of the MessageManager by the follwing line of code:
mm = wdThis.wdGetAPI().getComponent().getMessageManager();
when I try to show a message through mm.reportSuccess("TESTEST");
nothing is displayed. If I test my callable object in designtime all Messages created through MessageManager are displayed.
Can anyone give me a hint?
The message are only not displayed when the GP Process is started.
What I'm doing wrong ?
