Error while accessing application with custom components

Question

Hi experts,
I have an application (HAP_MAIN_DOCUMENT) of component FPM_OIF_COMPONENT which uses a Webdynpro component with the same name (HAP_MAIN_DOCUMENT). This Webdynpro component (HAP_MAIN_DOCUMENT) uses 2 other components (HAP_DOCUMENT_BODY and HAP_DOCUMENT_HEADER).
For my client requirement, i need to create the custom components by copying from standard components as the UI layout changes are quiet huge and not manageable with the enhancements. To accomodate this i have changed the standard configurations by replacing the standard web dynpro components with the custom ones copied. Apart fomr this there are no changes to the standard.
While trying to access the application, i am getting the error as Null object reference. the details of the error is as below. Please advice.
