Hi,

check the method WD_USAGE_INITIALIZE in component controller. This error occurs when you bind an interface view to other component.

Hi Arun,

I do not see this method on the component controller of my new component.

I can see it in the component controller context node implementation class.

But it is not implemented on it it is implemented on the class cl_bsp_wd_component_controller and it's empty.

Any idea?

Hi,

Redefine the method wd_usage_initialize, you have to bind the interface view context node to the context node of the component ZBP_DAT. Check for the component usage and bind the context nodes in method wd_usage_initialize.

METHOD wd_usage_initialize.
  CASE iv_usage->usage_name.

    WHEN 'zztest'.

          CALL METHOD iv_usage->bind_context_node
            EXPORTING
              iv_controller_type        = cl_bsp_wd_controller=>co_type_component
              iv_target_node_name  = 'TARGET_NODE'
              iv_node_2_bind           = 'SOURCE NODE'.

 ENDCASE.
ENDMETHOD.

In the above code specify the controller type, that is where you want to bind the context node, is it component or custom controller.

Regards,

Arun

Hi Arun first of all Thanks!!

i have redefined the method you told me in the component controller of my new component now called zerp_mat.

This is the code:

CASE iv_usage->usage_name.

    WHEN 'ERPMat'.
*
          CALL METHOD iv_usage->bind_context_node
            EXPORTING
              iv_controller_type        = cl_bsp_wd_controller=>co_type_component
              iv_target_node_name  = 'PARTNER'
              iv_node_2_bind           = 'PARTNER'.

The nodes i need to bind are called PARTNER in the component controller context and in the view context node, but i'm still getting the same error when i try to preview the view.

Thanks

Hi,

Check the name of the context node in both the components and also ensure that the base entity for both the context node are the same.

The components name is the same...

Can i send you a mail with the screenshots?

Thanks!!

Set a breakpoint in method DO_CONTEXTNODE_BINDING in view ZBP_DAT/ERPMat.

You probably just gave the wrong literals.
