Hi, wouldn't it make sense that you could set arbitrary variables on a ConversionException that would also be set on the ValidationError created in FormComponent#convertInput()? Currently, you can set the resource key that should be used for the error message, but you're limited to the few variables defined in FormComponent#convertInput(). I know I could override convertInput(), but I think user-defined variables would be a more elegant solution.
What do you think? cheers, Jonas
