Rakesh Gowda: I have investigated for DateField in the form, if user enters invalid date / non date or string value, field.getValue() always return null which prohibits me in differentiate between validation for null or required field and validation for non date value inputs.

Take a look at DateField.handleUnparsableDateString(...). If it throws an exception, it is internally converted to a flag value in DateField.changeVariables(...) and used to throw another exception when DateField.validate() is called, so I believe you should get a validation exception in this case.

Anyhow i have used this but while displaying i should display instant / immediate custom error messages in header of the application instead of displaying error message in form error component.
Please suggest anymore way of getting values to my controller for custom validation.

Maybe someone else can give a better answer for this one, but as starting points you could take a look at AbstractComponent.setComponentError(...), AbstractField.setValidationVisible(...) and AbstractField.getErrorMessage().
