Re: [S2.2.1] Struts Type Converter for sub-model objects not working?
Look at the bottom of your message and also the top.
'contact.contactLead.income' evaluated
to '$123' and you do not have a method
com.afs.entity.ContactLead.setIncome([Ljava.lang.String;)]

ContactCreateAction-conversion.properties file to convert the

Re: [S2.2.1] Struts Type Converter for sub-model objects not working?
I know. I don't have a setIncome(String) method. But I do have
setIncome(BigDecimal) method , hence the type conversion. Normally the
class MyCurrencyCoverter will covert the String to BigDecimal, but
it's never called. I am wondering what I am doing wrong that the
conversion class is not called.
