Appintegrator iView with custom parameter

Hello

I need to create an iView that generates the URL for a business server page and adds an user specific parameter. This parameter should be read from a database or LDAP.

I tried to implement this with the appintegrator iview as described in the document "How to Use the Application Integrator" on page 18pp.

As described I created a new service that returns the string (the parameter). It implements the interface as described in the pdf.

Now i would like to use the service in an call of an bsp-application (com.sap.portal.appintegrator.sap.BSP).

I don't know if my coding is incorrect or if I just dont know how to call my service. I tried it with "ApplicationParameter" and "DynamicParameter". I just get an errormessageFehler aufgetreten bei der Verarbeitung eines Request für :

iView : N/A

Komponentenname : N/A

Unable to process template 'myparam1=1&myparam2=<IDProvider1.test>', because 'IDProvider1' is an invalid sub-context of the context ''..

Can anyone give me a hint how to implement the interface and/or how to get the string as the content of the user-parameter? Perhaps i just dont understand how to get the parameter from my service...

Has anyone allready implemented such a thing?

thanks a lot

Stefan
