Question about attribute

Hi, i realize an enhacement to /SAPSRM/WDC_DO_SOCO_GAF_3 webdynpro component

on COMPONENTCONTROLLER i realize a postexit on PROCESS_EVENT.

i use the attribute WD_THIS.

data lv TYPE REF TO /sapsrm/if_pdo_xo.

CALL METHOD wd_this->mo_aom_soco->/sapsrm/if_cll_xo_mapper~get_pdo

RECEIVING

ro_pdo = lv.

in lv i can see the MT_INTERNAL_REF_TABLE attribute , but it is a private instance attribute.

and i need the data from this internal table attribute, but its private, im looking for other methods to obtain the data with no sucess

How i can get data from MT_INTERNAL_REF_TABLE?

thanks
