Validate two fields in a validator

Hi.

I have a date validator on each field which validates if they are a correct
date.
However, in one of the two date fields, I need to validate if it is after
the other date.

So this means I have to somehow get the other inputfield date in my
validator.
I have tried to do this using a listener on the other field, but it
retrieves null.

Any ideas how I can do this?

no problem.
To achieve what you need you also have another solution with the validator. (you can also check always the validation, even if is prevent when the user makes some action there is some times that the dates are setted programmaticly so the validation will prevent that some crazy data will go forward)
I will just pass the idea.
you extend the datevalidator class
override the method doValidation
override protected function doValidation(value:Object):Array {						results = [];			results = super.doValidation(value);			
						var StartTimestamp : Number = StartDate.getTime (); // create milisec from start date			var EndTimestamp : Number = StartEnd.getTime ();    // create milisec from end date        
/****  CHECK THE DATEs and return the results*/}
I hope will be enough for you to go to the next step.

sorry about the short reply.
but we can see here: http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/mx/controls/DateChooser.html#selectableRange
That will help your user to no select some dates
on the rangeStart : just put the selected date from the your component then you can add one day or something that adjust your BL.
I hope that helps.Miguel
