Hi Mariana,
I got (perhaps ?) a very similar problem just few minutes ago.
In my OnInitialization event handler, I have :
DATA: ta_usr01  TYPE TABLE OF usr01.
SELECT * FROM usr01 UP TO 100 ROWS
         INTO TABLE ta_usr01.
GET REFERENCE OF ta_usr01 INTO ta_data.
where
ta_data is declared as a page attribute TYPE REF TO DATA. 
When I tried to dislay the data in the Layout, I observed in Debud that ta_data was like this :
FREED STACK:{A:2*TYPE=%_T00004S00000072O0000002784}
And then "Eurêka !" 
It is because
ta_data is pointing on a local variable (ta_usr01) which has long gone (since the end of OnInitialization event handler) 
Everything went fine once I had declared ta_usr01 as a Page attribute (which means declared globally)
I guess you experience the same kind of problem.
Best regards,
Guillaume
