SPEL Review Page - not working at row level

Question

I have searched the forum for "review page" and "SPEL" try to find solutions and tryed the techniques, but still not working.
This is what I am trying to do Display Employee details ( empno,sal,comm,deptno) I wanted to display edit icon only when deptno=10 otherwise not.as mentioned in one of the threads i have added a column decode(deptno,10,1,0) DispEdit and set the rendered property of that edit icon/item. Wrote the code necessary to return TRUE or FALSE,
I think its setting rendered property based on the first record, not changing based on each record.
currently based on the first record and how I put the logic its 1. Displays the column/edit icon 2. Does not display the column.so it this statement right?
Please help.
I found 2 forums that said it worked
1. same as above
Problem Using SPEL
2. in the second thread uses row.setAttributeValue/populate...
SPEL
basically I am trying to create a review page with change indicator image ( I have sql that has select old_date,new_date, changes_YN columns).

Answer 1

Thanks for your reply.
I have set the rendered property to ${oa.viewobjectname.columnname}
which is same as u mentioned I guess. It is working based on the first row fetched but not based on each rows value.
As per Ramkumar in the below thread , SPEL does not work at row level is it TRUE can anypne confirm?
Re: Bound Values
I have been waiting to get someresponse from yesterday.
Anyway, as My plan was to use the logic to build review page ( to show Blue dot if old value is not equals to new value) , I have planned to replace SPEL with oracle SQL logic I wrote a sql which returns something like this, I could not find any better alternates ( wrost one was to create 7 VO's (bcaz i have 7 columns to disp) and apply SPEL there)
Select 'Empno' column, AEmpno Current,Bempno Proposed,decode( a.empno,b.empno,'','*') from xxx_v
union
Select 'Ename',Aename,Bename,decode(aename,bename,'','*') from xxx_v
* indicates Changed data.
