Zugriff über 'NULL' Objektreferenz nicht möglich.

Error analysis

An exception occurred that is explained in detail below.

The exception, which is assigned to class 'CX_SY_REF_IS_INITIAL', was not

caught in

procedure "HAS_CONTEXT_INPUT_ELEMENTS" "(METHOD)", nor was it propagated by a

RAISING clause.

Since the caller of the procedure could not have anticipated that the

exception would occur, the current program is terminated.

The reason for the exception is:

Es wurde versucht mit einer 'NULL' Objektreferenz (zeigt auf 'nichts')

auf eine Komponente zuzugreifen.

Eine Objektreferenz muß auf ein Objekt (eine Instanz einer Klasse)

zeigen, bevor man sie zum Zugriff auf Komponenten nutzen kann.

Entweder die Referenz wurde noch nie gesetzt, oder sie wurde mit

einer CLEAR Anweisung auf 'NULL' gesetzt.

Missing RAISING Clause in Interface

Can any one tell me what's wrong ?

I have also try to test some standard sap webdynpro demo ALV such as webdynpro " SALV_WD_DEMO_TABLE_SIMPLE" that use "SALV_WD_TABLE" as used component ,

I get this dump in my internet explorer browser :

Hello,

The component interface of SALV_WD_TABLE has a context node DATA which has to be mapped to a context node in the using component. So if you are using ALV component in your component, and embedded the interface view of ALV component in your window, you need to create an external mapping between a context node in your component and DATA node of used ALV component. To do this, expand component usages under your component, select the interface controller, drag a context node from your component controller on to DATA node of interface controller.

Hope this helps!

Best Regards,
