How read this atribute inside this class (abap oo).

Hi experts.

I'm programming within a class

I have within the class this attribute:

ME->ACTION_EVENTS

Within the ME- attribute> ACTION EVENTS I have this data

I want pass the parameter UI_ELEMENT_ID to a variable .

I try:

DATA:CL_E TYPE REF TO CL_WDR_SERVER_EVENT,

      l_action TYPE REF TO WDR_EVENTS.

FIELD-SYMBOLS:<EVE>   TYPE ANY,

               <fs_var> TYPE ANY,

               <fs_var2> TYPE ANY.

ASSIGN me->action_events TO <EVE>.

*ASSIGN COMPONENT 'CL_WDR_SERVER_EVENT' of STRUCTURE <EVE> TO <fs_var>.

*l_action = <EVE>.

*ASSIGN l_action->* to <fs_var>.

ASSIGN COMPONENT 'UI_ELEMENT_ID' of STRUCTURE <fs_var> TO <fs_var2>.

if <fs_var2> is ASSIGNED.

But didnt work.

Does anyone know how can I move this parameter for a variable?

THANKS
