I have created a Web Dynpro Application.
Here , i want to dynamically add a UI Element of type Interactive Form to my view and at run time only supply Template Source
I am writing the following code in DOMODIFYVIEW :
method WDDOMODIFYVIEW .
data: LR_CONTAINER type ref to CL_WD_UIELEMENT_CONTAINER,
LR_IF type ref to CL_WD_INTERACTIVE_FORM,
LR_FLOW_DATA type ref to CL_WD_FLOW_DATA.
LR_IF = CL_WD_INTERACTIVE_FORM=>NEW_INTERACTIVE_FORM( ).
LR_FLOW_DATA = CL_WD_FLOW_DATA=>NEW_FLOW_DATA( element = LR_IF ).
LR_CONTAINER ?= view->GET_ELEMENT( 'ROOTUIELEMENTCONTAINER' ).
LR_CONTAINER->ADD_CHILD( LR_IF ).
But it is giving a short dump saying
Access via 'NULL' object reference not possible
Can u think a possible problem
