Help me resolve this---- PLS-00302: component 'STRING' must be declared

Question

Can anyone please guide me in resolving the below error
The statement below is in the package spec.
TYPE rec IS RECORD ( proj AV_ACTIVITY.proj%TYPE, act AV_ACTIVITY.act%TYPE );
TYPE object_table_type is TABLE OF rec INDEX BY BINARY_INTEGER;
temp_as_rn object_table_type;
Then i am wrting a cursor in the package body and trying to access the component...but it throws up the
PLS-00302: component 'PROJ' must be declared
The below code is in the package body
CURSOR c2_memo_attr(proj_temp varchar2,act_temp varchar2) is
select distinct
dup.proj,
dup.proj_ds as proj_ds,
dup.act,
dup.act_ds as act_ds,
initcap(to_char(ac.eid, 'fmMonth DDth, YYYY')),
initcap(to_char(ac.lid, 'fmMonth DDth, YYYY')),
initcap(to_char(ac.act_due_date, 'fmMonth DDth, YYYY')),
dup.uc03 as Study_no
from dup_resource_status dup, av_activity ac
where ( ac.proj = proj_temp
and ac.act = act_temp)
and dup.proj = ac.proj
and dup.act = ac.act
and ac.ver = 0;
for c2_memo_attr_rec in c2_memo_attr(temp_as_rn.proj,temp_as_rn.act)
loop
text := 'abcd......'
     end loop;

Cursor loops are obsolete technology? Hmm, not sure I agree with you there.
Yes, sometimes they are an indication of slow-by-slow processing that could be better done in one dml statement, or with bulk collections, etc, but sometimes that's not the case - unless I'm missing something.
For example, I'm writing a procedure to take care of deleting partitions on a periodic basis, and I'm taking into consideration the case where there might be more than one partition to delete. So I'm using a cursor to identify the partitions to delete, and using a cursor for loop to loop round and execute the dynamic drop partition statement.
Since there's never going to be that many partitions, this isn't going to be particularly unperformant, and so I don't see a problem with using the cursor for loop construction for it.
I'd like to hear more on why you think it's obsolete technology in reference to my specific example - and also what you think I should be using.
