Package and table functions

Question

Hi i have created package like this.
create or replace
PACKAGE Package_x is
TYPE collect_tablex IS TABLE OF ASAP.tablex%RowType ;
/* TODO enter package declarations (types, exceptions, methods etc) here */
function f_tablefunc(arg_1 in number)
return collect_tablex;
END Package_x;
select * from table(cast (Package_x.f_tablefunc(54115,54114) as Package_x.collect_tablex ))
I have written function in body which is running fine when i debug.

ORA-00902: invalid datatype
00902. 00000 - "invalid datatype"
*Cause:   
*Action:
