Validate on event

Validation of the data is always calculated, but an additional information validated is used to determine if an error message should actually be displayed.

The validated property of a simple property is true if:

• the whole form was validated
• or options.initialValidation="always"
• or options.initialValidation="withData" and the property is initialized with non-empty data
• or options.validateOn="input" and the user inputed some data
• or options.validateOn="blur" and the user focused on the property then left

The option initialValidation can have the values never, withData and always (default is withData).

The option validateOn can have the values input, blur and submit (default is input).
