Custom Validators

[Oscar Hansen]

I am trying to create a custom validator for variable 'amount' in my domain class, such that the new value should be greater than previous by 0.50.

For example, lets say the previous value was 1.0, next time the value should be atleast: [previous value + 0.50] or more.

Thanks in advance for the help

amount validator: { val, obj -> 
			     def currentPrice = obj.getPrice()
			     if (currentPrice != null) {
				 return val >= (currentPrice + 0.50) }

We can do something like that or use creteria to get the max from the table. I got the problem resolved.
