Validation errors on Command Object

[too_many_details]

Hi,

I have an optional field on my form that represents a money amount.

I have declared the corresponding Command class to have a BigDecimal to hold this value.

Spring parses it correctly when the value is given but throws an exception when it is not.

Error code: Failed to convert property value of type [java.lang.String] to required type [java.math.BigDecimal] for property 'maxAmount'; nested exception is java.lang.NumberFormatException: null

How best to catch this and allow null for the BigDecimal?

Thanks

Rakesh

Problem is that "null" translates to an empty string for html input text boxes.

I suppose you could write your own property editor and register it on initBinder.
