wd4a ALV context binding problem

[Former Member]

Hi,

I create a compenent with component usage of SALV_WD_TABLE, and create context node flighttab with sub node booking, mapping the data node of SALV_WD_TABLE interface with the booking node.

and run the application, there is a short dump for the context mapping.

does anyone has any idea about it?

thanks and best regards

Hi Gang,

(1)

is the upper node attribute "selectionCardinality" set to 1..?. Try this out. If the top node is not selected then the ALV will not receive the child node for an element of the upper node --> the ALV receives nothing.

(2)

did you add any dynamic attributes to the context node which is handed over to the ALV? The ALV can only handle static attributes. This can be achieved by dynamically creating the static structure containing static and/or dynamic attributes --> The node handed over to the ALV is then registered as static even though everything was created dynamically.
