Exception during cross-component navigation

Question

Hi all,
My requirement is to navigate from the task to the Case.
After doing the necessary things for event handling, I have created a outbound plug in the component BT125H_TASK in the view 'TaskDetails'. I have added this outbound plug in the main window with the necessary code for the outbound plugs. I have also added this outbound plug to the main window and component interface in the runtime repository.
I am using the inbound plug 'Overview' (mainwindow) from the component CRMCMP_CMG. I have added this inbound plug under mainwindow and component interface in the runtime repository.
The outbound and inbound plugs are defined along with source and target IDs in SPRO also (CRMS_UI_TLINK and CRMC_UI_NBLINKS).
Now when I click on the case link in 'TaskDetails' page, it gives the following error:
"Invalid entry in the navigation queue
An exception has occurred Exception Class  CX_BSP_WD_INCORRECT_IMPLEMENT - Define NavigationalLink TOCASEDISP for source view CUBT125HTASK.MainWindow.
Program:  SAPMHTTP 
As both the components BT125H_TASK and CRMCMP_CMG are parent components themselves (think so), I have not added the outbound/inbound plugs under component usage. Do i need to do anything here??
Are the components BT125H_TASK and CRMCMP_CMG root components?
Any help is highly appreciated.
Thanks in anticipation.

Hi All,
I could solve it myself. Thanks for the time.
The problem was I tried to navigate directly from the component ''BT125H_TASK' to the component 'CRMCMP_CMG', as I could not find any parent for BT125H_TASK earlier.
Now I could find its parent component which is 'BT110M_ACT'.
The outbound plug created in the task component has to be added to the component usage of 'BT110M_ACT' and the delegation should be done. The other things are the same. It works fine.
