Triggering multiple constraint validations at once

I have a form with a submit button, if the user presses the submit button I want all validations that I associate with the form fields to run.

My code is basically just constraint1.validate(comp1, val1); constraint2.validate(comp2, val2); etc

The problem I'm having is that when a validation fails, a WrongValueException is thrown and the following validations will not trigger (if constraint1 fails in this exampel, constraint2's validation will never run). I want all the errors to be displayed at once so the user can see everything that needs to be fixed.

How can I accomplish this? I want all the validations to run separately so that each related form control gets its own error dialog.

dorr: You seem to have copy-pasted the code from my post, since it contains the same syntax error :-)

Please paste the actual code you are using

Hi dorr,
it is difficult to guess what is going wrong there. Code seems ok to me. Did you try printing the actual errors list values?
What version of ZK are you using?

Thanks
- Ashish

I have done what was recommended above, but only the last error is displaying. I see 2 being passed to WrongValuesException from debugging. What am I doing wrong?

if (errors.size() > 0) 
{
	WrongValueException[] es = new WrongValueException[errors.size()];
	for (int i = 0; i < errors.size(); i++) 
        { 
	      es<i > = errors.get(i);
	}
	throw new WrongValuesException(es);
}

Thank you Ashish! That was what I was looking for.

In case anyone is interested it seems like you cannot nest WrongValuesExceptions inside of each other, so you will need to iterate through and add to a new array to flatten the structure, and you also want to avoid unsafe cast warnings. Here's what I ended up doing:

List<WrongValueException> errors = new ArrayList<WrongValueException>();
try {
	performSeveralValidations();
} catch (final WrongValuesException wves) {
	WrongValueException[] es = wves.getWrongValueExceptions();
	for (int i = 0; i < es.length; i++) {
		errors.add(es<i >);
	}
}
// > Other validations here...
if (errors.size() > 0) {
	WrongValueException[] es = new WrongValueException[errors.size()];
	for (int i = 0; i < errors.size(); i++) { 
		es<i > = errors.get(i);
	}
	throw new WrongValuesException(es);
}
