BAPI initialize error at wdDoInit of controller

Hi all,

I'm trying to call a simple BAPI from webdynpro but a NullPointerException is thrown at WdDoInit() of controller.

At Line: wdContext.nodeBapi_Debtor_Getdetail_Input().bind(new Bapi_Debtor_Getdetail_Input());

The stack is:

java.lang.NullPointerException: at com.sap.tc.webdynpro.modelimpl.dynamicrfc.AiiModelClass.createNewBaseTypeDescriptor(AiiModelClass.java:220)

at

I could connect to another BAPIs using the same procedure. I don't know why this one doesn't work.

I'll appreciate any response.

Thanks in advance,

Diego.
