Hi Owen,
In your validationFailedWithException() method, add this:
public void validationFailedWithException(java.lang.Throwable exception,
java.lang.Object value, java.lang.String keyPath) {
// add to array of error messages
....
// try to force the value
try {
// value = the Object parameter to this method (2nd parameter)
// keyPath = the String parameter to this method (3rd parameter)
takeValueForKeyPath( value, keyPath );
}
catch (IllegalArgumentException e) {
// just ignore it... we've already added the exception to the array
of validationErrors
}
}
Regards
Peter

Hi All,
I have an attribute in an entity that has a width of 1500 char. I have
over ridden the validate method for it inside the entities java
class.....
public String validateRqfJustification(String newState) throws
NSValidation.ValidationException
{
if ( newState != null ) {
if (newState.length() > 1500) {
throw new NSValidation.ValidationException("The RQF
Justification can not be longer than 1500 characters");
}
}
return newState;
}
This gets called fine when I try to save it.
However if I submit the form and the text field contains more than
1500 chars, a validation error is thrown, without going into this
method because it checks it against the width inside the model.
I catch this exception inside the component
validationFailedWithException() method, the page gets return I display
the error message ( not the nicely formatted one form above, but the
default one ). BUT the value of the form in the feild has been reset
to what it was before they click the button. This is not what I want.
I want to tell them they can't save but the value in the field should
stay the same as what they just typed.
So 2 questions :
1) When a form is submitted why doesn't it use my validation method
for that attribute ? What validation is it calling ? i.e.
validateforUpdate() ?
2) How can I get the value the user typed to stay in the form,
instead of being truncated back ?
