Mapped context nodes and attributes cause runtime exception

[michael_hill]

I am having a problem with mapped context attributes and nodes. I'm new at webdynpro, so maybe I'm missing something here. Is there something special I need to do to make mapped context attributes and nodes work?

Whenever I create a mapped link between any of my component controller context nodes or attribute values to my context on a view, I get the following stack dump (include below). However, if I create a data link and don't map the attribute or node, the same view will run and I can access the attributes or nodes by getting a reference to the controller's context. For example:

String userId = wdThis.wdGetVoiceUserManagementController().wdGetContext().currentVoiceUserElement().getSapUserID();

I also created some test attribute values and nodes that are not being used by any code in my project and just by mapping it, it causes the runtime stack dump.

Regards,

Michael

The NoSuchMethodError indicates a problem with your environment. Please ensure that the NetWeaver developer studio and the J2EE engine have the same Web Dynpro version / service pack.

Thanks! I updated my webAS server and it works like a charm.
