selectItems alsway throw validation error
Hi!
I already seached this forum but found no answer for my problem that I hope
is simple to fix.
I have a selectOneListBox that displays Employees that should be selected. I
wrote a converter but I always get a "Wert ist keine gültige Auswahl" -
means "value is invalid"
Here is my code:
<t:selectOneListbox id="employees" size="1"
value="#{newScheduleEntryForm.responsibility}">
<t:selectItems value="#{peopleHandler.allEmployees}" var="thisItem"
itemLabel="#{thisItem.firstName} #{thisItem.lastName}"
itemValue="#{thisItem}" />
</t:selectOneListbox>
In newSheduleEntryForm
public EmployeeVO getResponsibility() {...}
public void setResponsibility(EmployeeVO responsibility) {...}
in peopleHandler
public List<EmployeeVO> getAllEmployees() {...}
the Converter
public EmployeeVO getAsObject(FacesContext context, UIComponent component,
String value) throws ConverterException {
if ( value == null) return null;
for ( EmployeeVO employee : ps.getAllEmployees())
{
if ( employee.getId().toString().equals(value))
{
System.out.println("employee found: " + employee.getLastName()); //this is
put to console so the converter works!
return employee;
}
}
throw new ConverterException ("EmployeeConverter.getAsObject: There is no
EmployeeVO for Value " + value + ", type=" + value.getClass().toString());
}
public String getAsString(FacesContext context, UIComponent component,
Object value) throws ConverterException {
if ( value == null) return null;
if (value instanceof EmployeeVO)
{
EmployeeVO person = (EmployeeVO) value;
return person.getId().toString();
}
throw new ConverterException ("EmployeeConverter.getAsString: This
is no EmployeeVO, value=" + value.toString() + ", type=" +
value.getClass().toString());
}

Ok, I fixed that but had no success. If I do not use a SelectBox but a
simple text-input to type in the ID of the employee it works fine. No
convertions or validation problems...

Hi Stephan!
There was a typo in my equals method. So your hint (serializable and
equals
method) was perfect! Now it works!
Thanks a lot!

Hi Simon,
probably your Employee-Class is not serializable and do not implement equals?
If it is not implementing equals, every instance is different...

Stephan
