How to get value from one context node to another context node in different views

[Former Member]

Hi gurus

I have the following problem.

I have 2 context nodes (context node1 and context node2) in views different. the context node1 is bound to the component controller.

I need get a data from context node1 in the getter_method of an attribute from context node2.

I know how to get a reference to the component controller,you can do it as follows.

lr_controller TYPE REF TO CL_BUD_BSPWDCOMPONEN_IMPL "Implementation class of the component controller

lr_controller ?= me->comp_controller.

but the Access to protected attribute "COMP_CONTROLLER" is not possible.

Can you help me telling me how do I read the data of the context node 1 from the method of the attribute in the context node 2

Regards,

Dear Felipe,

  One of the step to access component controller form CNXX class is

           Create reference attribute of type component controller in CNXX class

           say GR_COCO type ref to (component controller )

           Then assign it in DO_PREPARE_OUTPUT.

               me->typed_context->(NODE)->GR_COCO ?= me->comp_controller.

Now you can read your Component controller form your getter or setter method.

Thanks and Regards

Hi Felipe,

is the value of context node that you want to get is from a model context node or value context node?

if it is from a model context node, it may be able to be accessed from root and using bol relation

you can go the root by using method get_root(). after that you can get access to its child using method get_related_entity( ).

hopes it helps

cheers
