BAdI error : type of EXIT_REF1 cannot be converted to the type of EXIT_REF

Question

Hi all,
The below was the posted earlier for BAdI. Ihave followed all the steps. And i have written the below code. Syntactically it is not showing any errors, but when i am activating i am getting error
like " The type of EXIT_REF1 cannot be converted to the type of EXIT_REF". where i am doing the mistake..??
1) execute Tcode SE18.
2) Specify a definition Name : ZBADI_SPFLI
3) Press create
4) Choose the attribute tab. Specify short desc for badi.. and specify the type :
multiple use.
5) Choose the interface tab
6) Specify interface name: ZIF_EX_BADI_SPFLI and save.
7) Dbl clk on interface name to start class builder . specify a method name (name,
level, desc).
Method level desc
Linese;ection instance methos some desc
8) place the cursor on the method name desc its parameters to define the interface.
Parameter type refe field desc
I_carrid import spfli-carrid some
I_connid import spefi-connid some
9) save , check and activate…adapter class proposed by system is
ZCL_IM_IM_LINESEL is genereated.
IMPLEMENTATION OF BADI DEFINITION
1) EXECUTE tcode se18.choose menuitem create from the implementation menubar.
2) Specify aname for implementation ZIM_LINESEL
3) Specify short desc.
4) Choose interface tab. System proposes a name fo the implementation class.
ZCL_IM_IMLINESEL which is already generarted.
5) Specify short desc for method
6) Dbl clk on method to insert code..(check the code in “AAA”).
7) Save , check and activate the code.
REPORT ZBADI_TEST .
tables: spfli.
data: wa_spfli type spfli,
it_spfli type table of spfli with key carrid connid.
*Initialise the object of the interface.

end-of-selection.
loop at it_spfli into wa_spfli.
write:/ wa_spfli-carrid,

wa_spfli-cityfrom,
wa_spfli-deptime,
wa_spfli-arrtime.
hide: wa_spfli-carrid, wa_spfli-connid.
endloop.
at line-selection.
check not wa_spfli-carrid is initial.
create object exit_ref.
exit_ref1 = exit_ref.   "" The type of EXIT_REF1 cannot be converted to the type of EXIT_REF"
call method exit_ref1->lineselection
EXPORTING
i_carrid = wa_spfli-carrid
i_connid = wa_spfli-connid.
clear wa_spfli.
Thanks in advance

Hi,
Both are of different types
data: exit_ref type ref to ZCL_IM_IM_LINESEL,
exit_ref1 type ref to ZIF_EX_BADISPFLI1.
Assiging one type another type is not allowed.
