Access via 'NULL' object reference not possible

46 Views

Hi,

When executing my WDA i am getting the following dump.

The following error text was processed in the system RD2 : Access via 'NULL' object reference not possible.

The error occurred on the application server INBDQ-S-RD2_RD2_01 and in the work process 1 .

The termination type was: RABAX_STATE

The ABAP call stack was:

Method: GET_ATTRIBUTE_EXTERNAL of program CL_WDR_VIEW_ELEMENT_ADAPTER===CP

Method: IF_WDR_VIEW_ELEMENT_ADAPTER~SET_CONTENT of program /1WDA/L0STANDARD==============CP

Method: IF_WDR_VIEW_ELEMENT_ADAPTER~SET_CONTENT of program /1WDA/L8STANDARD==============CP

Method: IF_WDR_VIEW_ELEMENT_ADAPTER~SET_CONTENT of program /1WDA/L7STANDARD==============CP

I checked in st22.it is showing the error in

method get_attribute_external.

data data_container type ref to cl_wdr_data_container.

data attribute type wdr_attribute_pointer.

data client_component type ref to cl_wdr_client_component.

attribute-attribute_name = i_binding->attribute_name.

attribute-element ?= get_bound_element( i_binding ).

client_component ?= attribute-element->node->controller->component->data_container_superior.

data_container = client_component->data_container.

e_value = data_container->get_and_format( attribute = attribute ).

endmethod.

What could be the error.
