Hi,
I would like to push some messages to the UI from the GET methods. I have new context node and i want to do my validations and push some messages from each attribute in the context node. How can i do that ?

Hello,
This won't answer your question, but if you need to do some validations and push some messages accordingly, why don't you use method DO_PREPARE_OUTPUT or DO_VALIDATE_INPUT / DO_FINISH_INPUT of your controller class?
Because I'm not sure the GET methods of the model class si the best place to put your coding in this case.
Anyway, here is some example of how to throw messages to the UI:
DATA: lv_msgsrv          TYPE REF TO cl_bsp_wd_message_service.
lv_msgsrv = cl_bsp_wd_message_service=>get_instance( ).
lv_msgsrv->add_message( iv_msg_type       = 'I'
                           iv_msg_id         = 'MESG'    "#EC NOTEXT
                           iv_msg_number     = '001' ).
Hope this helps,
