Need help with Validation Rule

[gibelium]

I have a Bean with two depending Properties. The value-Property depends not only on the existance of the paymentType-Property but accessorily on its value.

I tried the following:

add("amount", ifTrueElse(eq("paymentType", PaymentType.CREDIT), 
            value("amount", gt(0.0d)), value("amount", lt(0.0d))));

The ErrorMessage:

org.springframework.beans.NotReadablePropertyException: Invalid property 
'paymentType' of bean class [java.lang.Double]: Bean property 'paymentType'
is not readable or has an invalid getter method: Does the return type of the
getter match the parameter type of the setter?

How do I have to implement that ifThanElse Contraint for a Property depending on the Value of an other one?

Thanks for hints,
sebastian

That is currently a weak point in spring rcp. If a property constraint is nested in a non property constraint it will not be processed in the right way. You have to create a IfTrueElsePropertyConstraint which knows how to handle the property constraints.

Thanks for the reply Mathias,

do I have to implement that case of PropertyConstraint by myself or is it possible to built it out of the existing Constraints? Did you implement something like that, yet?

By now I just needed the "simple" Contraints provided in the sample apps and the docs. After digging in the source today I did not really get the whole image. If there is any, an Example would help understand things, I think.
