When calculating totals itterater run twice

Question

Hello,
=> when I check the log file I see that the itterater runs twice
=> I have a view Wedstrijden with 2 transient (Totaal & TotaalMin)
=> I have made an object E_Som
package oracle.foot.userinterface;
import oracle.jbo.domain.Number;
public class E_Som {
private Number som1;
private Number som2;
public E_Som(
Number som1,
Number som2) {
this.som1=som1;
this.som2=som2;
public E_Som() {
public void setSom1(Number som1) {
this.som1 = som1;
public Number getSom1() {
return som1;
public void setSom2(Number som2) {
this.som2 = som2;
public Number getSom2() {
return som2;
=> I have created a getSumOfTotal in the WedstrijdenImpl.java
public E_Som getSumOfTotal() {
System.out.println("in get SumofTotal ");
E_Somtest = new E_Som();
sumOfSal = new Number(0);
sumOfSal2 = new Number(0);
RowSetIterator rsi = createRowSetIterator(null);
while (rsi.hasNext()) {
System.out.println("in de itterater "+ sumOfSal);
System.out.println("in de itterater2 "+ sumOfSal2);
Row r = rsi.next();
Number curSal = (Number)r.getAttribute("Mntrecette");
if (curSal != null) {
sumOfSal = sumOfSal.add(curSal);
Number curSal2 = (Number)r.getAttribute("Mntfrarb");
if (curSal2 != null) {
sumOfSal2 = sumOfSal2.add(curSal2);
System.out.println("Na de itterater "+ sumOfSal);
rsi.closeRowSetIterator();
E_Somtest.setSom1(sumOfSal);
E_Somtest.setSom2(sumOfSal2);
return E_Somtest;
=> In the WedstrijdenRowImpl.java if have change the get's of Totaal & TotaalMin in
public Number getTotalMin() { 
return ((WedstrijdenImpl)getViewObject()).getSumOfTotal().getSom2();
public Number getTotaal() {
System.out.println("voor de return van get Totaal ");
return ((WedstrijdenImpl)getViewObject()).getSumOfTotal().getSom1();
=> In the jspx I have
#{bindings.WedstrijdenlijstTotaal.inputValue} &
#{bindings.WedstrijdenlijstTotalMin.inputValue}
=> When I call the detail jspx I see in the log that the getSumOfTotal is used twice.

Answer 1

Yes, So you have to figure out what's causing that. The only part of your code that I can see that does any parsing is this:fltPrice = Float.parseFloat(txtPrice.getText()); so that's probably what's throwing the exception.
So basically, you need to put some code around there to check the return value of txt.getText and see if it's in valid floating-point number format. If it's not in valid format, then when you call parseFloat, it will throw that exception.
and I am new to programming , so I'm not quite
for sure what you mean by code tags.It has nothing to do with programming. These forums have special markup tags. You can make text bold or italic or underlined. When you post code, put "[code]" before it and "[/code]" after it, and the forum software will display the code legibly (like it did above).
