Tableview using filter - wrong DataBinding?

Question

Using a filter in my tableview made me notice a behaviour of which I don't know if I forgot some important detail or just discovered something ...
System: WebAS 6.20, SP45
In my tableview I use data binding quite extensively, and after implementing and testing the filter I came across this situation:
Chose a filter that would only display the 3rd entry of my table ... these are 4 of the render_cell_start parameters with their values:
p_cell_id       mdl_vplaner_plan_data[3].evttx
p_cell_binding  //model/plan_data[1].EVTTX
p_row_index     3
p_row_key       3
Of course I set parameter keyColumn for the tableView, so row_index and row_key are the same. However, in the string <b>p_cell_binding</b> it is not the row_key but the number of the row processed in my iterator that is used.
This caused the values of row with key '1' to appear in the first tableview-row wherever p_cell_binding was used.
A workaround for this was not hard to find, just copy p_cell_binding to lv_cell_binding and replace the number there ...
But any input from your side on this is appreciated. Did I not think about something regarding data binding? Did you come across the same situation using iterators with data binding and filter?
Hoping for a lil' discussion

David / Raghu - Thanks for u'r replies and apologizes for not posting question with proper material.
Am posting my code and the error message from the screen.
Code :
IFNULL(FILTER("Fact - MBS Loan Transactions"."OUTSTANDING PRINCIPAL" USING "Dim - MBS Loan"."LOAN TYPE HPD/HDC/BNK" = 'HDC'),0)
Error :
nQSError: 10058] A general error has occurred. [nQSError: 22032] Function FILTER requires at least one measure attribute in its first argument. (HY000)
SQL Issued: SELECT "Dim - MBS Loan"."LOAN AMOUNT", "Dim - MBS Loan"."LOAN TYPE HPD/HDC/BNK", "Dim - MBS Loan"."LOAN TYPE SEN/SUB", "Dim - MBS Project"."PROJECT NAME", "Dim - MBS Project"."PROJECT NUMBER", "Fact - MBS Loan Transactions"."AR BALANCE INTEREST", "Fact - MBS Loan Transactions"."GL BALANCE INTEREST", IFNULL(FILTER("Fact - MBS Loan Transactions"."OUTSTANDING PRINCIPAL" USING "Dim - MBS Loan"."LOAN TYPE HPD/HDC/BNK" = 'HDC'),0) FROM "Financials - MBS"
OK (Ignore Error)
Please continue answering my queries. Since am a newbie your answers won't be just a reply but it's actually learning for me.
Thanks.
