I don't believe anything but an Integer or null will be sent through
this method. The only other thing I believe you need to check for is if
the Integer is not less than zero:
if (newCountOfUploadRemainger.intValue()<0)
throw new NSValidation.ValidationException("...");

I am trying to use the code below to do some validation on a
WOTextField that is bound to an String var and entered into the
database progmatically by setting the value of it's corresponding
EOCustomObject.
Basically I want to validate that a character is not trying to be
entered into the database.
Here the code I am using, how do I complete it?
// CountOfUploadRemainder: is a required field in the form
public Integer validateCountOfUploadRemainder(Integer
newCountOfUploadRemainder)
throws NSValidation.ValidationException {
if (newCountOfUploadRemainder == null) {
throw new NSValidation.ValidationException("Enter 0 if
you are not uploading any images, otherwise state the number of images
you wish to upload. Enter only digits and avoid text characters. Try
something like \"1\", \"01\", \"10\" etc.");
}
if (newCountOfUploadRemainder != null)
{
// THIS IS WHERE i NEED THAT VALIDATION
// THE CODE HERE IS NOT RIGHT, DON'T KNOW WHAT TO USE
char c = newCountOfUploadRemainder;
if (!Character.isDigit(c))
{
throw new NSValidation.ValidationException("The
value \"" + newCountOfUploadRemainder + "\" is not a valid number. Use
only digits and avoid text characters. Try something like \"1\",
\"01\", \"10\" etc.");
}
}
return newCountOfUploadRemainder;
}
I would appreciate your help... Thanks
Jonathan
