Viewobject transcient attribute update value base on other field

Question

Dear All,
I have a viewobject with a transcient attribute which is calculated based on some other attributes queried from the DB. I have set the default value of the transcient field using the express:
adf.object.viewObject.getFTType()
and the getFTType() in the viewObjectImpl will return a string base on other fields' values;
Then I test it in the AM Model tester and it looks fine. However, when I drag this VO to a Table in the page, the transcient field column always showing the same value on every rows instead of showing different values base on the other fields on each row.
I've added a button to print the selected row values in the table and after I click on the button, the transcient field column is updated according to my selected row other fields' values and it updates the value for the whole column instead of only the selected row.
I wonder if there is sth wrong I did? Thanks a lot.
The getFTType() method is pasted here:
public String getFTType() {   
Row row = this.getCurrentRow();
String ftType = "";
try {
if (row.getAttribute("TxType").toString().equals("99")) { // all non-GJs
if (row.getAttribute("InputFutureTrfDate") != null) { // Future type FT
if (row.getAttribute("TiMToMYorn") != null) {
if (!row.getAttribute("TiMToMYorn").toString().toLowerCase().equals("y")) {
if (row.getAttribute("TrfMethod").toString().equals("5")) {
ftType = "ECI FT (Future)";
} else {
ftType = "Misc FT (Future)";
} else {
ftType = "Misc FT M to M (Future)";
} else {
if (row.getAttribute("TrfMethod").toString().equals("5")) {
ftType = "ECI FT (Future)";
} else {
ftType = "Misc FT (Future)";
} else { // non-future FT
if (row.getAttribute("TiMToMYorn") != null) {
if (!row.getAttribute("TiMToMYorn").toString().toLowerCase().equals("y")) {
if (row.getAttribute("TrfMethod").toString().equals("5")) {
ftType = "ECI FT";
} else {
ftType = "Misc FT";
} else {
ftType = "Misc FT M to M";
} else {
if (row.getAttribute("TrfMethod").toString().equals("5")) {
ftType = "ECI FT";
} else {
ftType = "Misc FT";
if (row.getAttribute("TxType").toString().equals("11")) {
ftType = "GJ Interest Income";
if (row.getAttribute("TxType").toString().equals("12")) {
ftType = "GJ Bank Charge";
if (row.getAttribute("TxType").toString().equals("13")) {
ftType = "GJ Others";
} catch (Exception e){
e.printStackTrace();
return ftType;
}

Did you set recalculate on the field you are basing its value on.
