I found this related question
http://stackoverflow.com/questions/4970443/stop-custom-validator-from-firing-on-each-keystroke

however, it is not clear to me where and how should I implement that solution. It seems to me that there should be some global switch that should allow to alter the behavior and either fire validaiton on each keystroke or only upon exiting the field.

>So, now, after I open the Add dialog and type the first digit, the doesClientNoExist method fire. I want to be able to complete the input before firing the validations. I seem to have the similar problem with phone or email - the validation messages show right away after I start typing.
