custom error message for constraints

[adwin grails]

Hi,

I have domain with constraints like min value must greater than 0

I have no idea how to change the message if the constraints are not passed.

which file i need to edit to do that ?

I also need to display the values some properties as well .. like

"you cannot make any transaction because your balance is less than 100. Your current balance is ${currentBalance}. Your current balance is ${lastBalance} and amount that need to be deducted ${deductedValue} "  

note: my class Transaction has properties: lastBalance, deductedValue, currentBalance

the currentBalance has min(100) constraints

at the moment I could display the currentBalance using {2} in message.properties. But I also need to inform user about lastBalance and deductedValue as well .. how to do that ?

I'd suggest using a custom validator in this case, and registering a
custom error on the Errors object with your additional args.
