[Question] xml mapping

[tokazio]

Name:

private String first;
private String last;
//getter/setter

Person:

private Name name;
//getter/setter

PersonDto:

private String firstName;
private String lastName;
//getter/setter

How to map Person to PersonDto with XML ?

name.first -> firstName name.last -> lastName

This doesn't work:

<conversion name="firstname" to="firstName" type="DYNAMIC">
    return ${source}.getName().getFirst();
</conversion>

Can you add mapping code and the error generated?

Full xml config:

<?xml version="1.0" encoding="UTF-8"?>
<jmapper
    xmlns="https://jmapper-framework.googlecode.com"
    xmlns:xsi="https://jmapper-framework.googlecode.com/svn"
    xsi:noNamespaceSchemaLocation="jmapper.xsd">    
    <class name="net.esyo.mappersperfs.PersonDto">
        <attribute name="birthDate">
            <value name="birthDate"/>
        </attribute>
        <attribute name="aliasesList">
            <value name="knownAliases"/>
        </attribute>
        <conversion name="firstname" to="firstName" type="DYNAMIC">
            return ${source}.getName().getFirst();
        </conversion>
    </class>    
</jmapper>

Testing it with Junit and assertJ. Direct mapped fields are ok.

No stack, but PersonDto.firstName is null

I don't know if

<conversion name="firstname" to="firstName" type="DYNAMIC">
    return ${source}.getName().getFirst();
</conversion>

Is the right config to map Person.name.first to PersonDto.firstName

[tokazio]

I'm comparing bean mapping framework. You can get the project here

[avurro]

The mapping is not applied because the field "firstName" is not configured. Between attributes there isn't a field "firstName" mapped, so the conversion is ignored

[tokazio]

ha ok! i understand now... thanks! this one works, and it's fast ;)
