How Attributes declared in Component level can be used in All the views

Question

How Attributes declared in Component level can be used in All the views
For Example :
say :             context type ref to if_wd_context_node.
is declared at component controller level and check box public is checked !!
How can we use this any view in same WDP Component..
For suppose : in this case
We want to get the ref of child node using above declared attribute..
How is it possible?
Say in detail

Answer 1

You can do this by doing the exact same like you did with the if_wd_context_node.
1. Define attribute in Comp Controller and set it PUBLIC.
2. Access the attribute over the reference of the comp controller, i.e. wd_this within the comp controller itself or wd_comp_controller within somewhere else in the component.
So if you have, lets say, this defined as attribute in your comp controller:
Z_MY_TABLE_REF  [X] TYPE REF TO [X] PUBLIC   CL_WD_TABLE.
And then you want to catch the reference into a local variable within a method or the like within a view:
DATA: lo_my_table_ref TYPE REF TO CL_WD_TABLE.
lo_my_table_ref = wd_comp_controller->z_my_table_ref.
Lekha has already said so as well, I don't really understand where the problem is
