Page, controller, or MIME BSPWDComponent.do already exists in application in sap crm webui

[Former Member]

Hi Experts,

I need to bind BTAdminI of BT112H_SC component context node to other custom component BTAdminI context node.

BT112H_SC is already enhanced .For this custom component also generated.But when i am trying to enhance component controller i am getting error like "

Page, controller, or MIME BSPWDComponent.do already exists in custom application in sap crm webui".

So i opened custom component(which was generated when BT112H_SC is enhanced). When I opened this custom component there was no z class generated for component controller for this custom controller.

To bind BTAdminI of BT112H_SC i need to write the binding logic in wd_usage_initialize.It is not allowing me to edit.Hence I did implicit enhancement to write binding the logic and also created component usage.and I also created context node properly in custom component.

But my problem is i am not able to see Items data in custom component.Means binding is not happening properly.

Could you please help me on this issue to bind BTAdminI of BT112H_SC in custom component

Hi

I'm not sure if you use the term "custom component" right!?

If you enhance an SAP standard component a Z-component is created- but this is not a "custom component"! And you only do changes in the SAP standard component (within the extension set)!

If you have created a completely standalone Z-component and named your enhancment component (popup for enhancment objects when initially enhance a standard component), then you messed things up!

Please provide a screen shot of the standard component BT112H_SC, the enhancment component (Z_BT112H_SC?) and your custom component!

Hi Domi,

Now i am able to add my code in ZComponent WD_USAGE_INITIALIZE method.But still i have one problem.

I am not able to see any values at BTAdminI .Data is not filling in collection wrapper.

Hi

so you enhanced the component but need to enhance the compcontroller also?

Maybe the Fast Item Switch is active - see CL_BT112H_S_BSPWDCOMPONEN_CTXT=>CLASS_CONSTRUCTOR and Note 2149971

If so, see view BT112H_SC/ItemList for possible solution (CL_BT112H_S_ITEMLIST_IMPL->ON_ITM_SEARCH)

BTW: please try to use the functional style for method calls

      iv_usage->bind_context_node( iv_controller_type  = cl_bsp_wd_controller=>co_type_component
                                   iv_target_node_name = 'BTADMINI'
                                   iv_node_2_bind      = BTAdminI' ).
