Method Detail

isValid

public boolean isValid(org.infohazard.maverick.flow.ControllerContext cctx,
                       FormBeanContext formBeanContext,
                       java.lang.String fieldName,
                       java.lang.Object value)

Checks if value is valid. This method should return true if validation succeeded or false otherwise. For error handling you have two options:

• Use the callback method getErrorMessage. You should use this if the error message is allways the same (except for maybe some parameters in the message).
• For more flexibility, like if you have more stages of validation that each generates its own message(s), you can register errors directly with the formBeanContext

Parameters:

cctx - maverick context

formBeanContext - context with bean for this currentRequest

fieldName - field name of parameter

value - the value of this parameter

Returns:

true if valid, false if not.

getOverrideValue

public java.lang.Object getOverrideValue(java.lang.Object value)

if value is not valid, get the custom value to set as the field override in the form.

Parameters:

value - the original input value

Returns:

the value that should be used as override value
