Hi,
I am stuck on a mapping issue that doesn't seem to be clearly documented in
JiBX. The problem I find is not being able to map a class attribute which
is a collection and the object in the collection is a sub-class. This seems
doable and OK until I have to map an XML element to an attribute of the
superclass. Am I making sense here?
In the following example, I am mapping an Organisation, which has a
collection of Opportunity. Each Opportunity has in turn a collection of
Activity, which is a sub-class of AbstractLookupValue (this is not actually
an abstract class, but don't worry!).
The problem is that the Activity is not mapped. There is a setter in
AbstractLookupValue, called subTypeId, which determines the type of
Activity. This setter is not being called.
I would appreciate if you could give me assistance in making this work. An
example of the codes is as follows below.
<?xml version="1.0" encoding="UTF-8"?>
<binding>
<mapping name="abstractlookupvalue"
class="domain.AbstractLookupValue" abstract="true">
<value name="id" field="subTypeId" style="attribute"/>
</mapping>
<mapping name="activity" class="domain.Activity"
extends="domain.AbstractLookupValue">
<structure map-as="domain.AbstractLookupValue"/>
</mapping>
<mapping name="organisation" class="domain.Organisation">
<namespace uri="http://www.blablabla.org.uk/uploader";
default="elements"/>
<value name="partnerId" field="vbase2Id" style="attribute"/>
<collection name="opportunities" field="opportunities"
usage="required" create-type="java.util.ArrayList">
<structure name="opportunity"
type="domain.Opportunity">
<value name="uploaderId" field="vbase2Id"
style="attribute"/>
<value name="title" field="title"/>
<value name="summary"
field="shortDescription"/>
<value name="description"
field="description"/>
<value name="benefits" field="benefits"/>
<value name="requirements"
field="qualifications"/>
<collection name="activities"
field="activities" create-type="java.util.ArrayList">
<structure
map-as="domain.Activity"/>
</collection>
</structure>
</collection>
</mapping>
</binding>
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<organisation
xmlns="http://www.blablabla.org.uk/uploader";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
partnerId="ufohybrid">
<opportunities>
<opportunity uploaderId="1">
<title>A</title>
<summary>B</summary>
<description>C</description>
<benefits>D</benefits>
<requirements>E</requirements>
<activities>
<activity id="2" />
</activities>
</opportunity>
</opportunities>
</organisation>
public class Activity extends AbstractLookupValue
{
// ...
}
public class AbstractLookupValue extends AbstractPersistable<Long>
{
// ...
}
public class Organisation extends AbstractPersistable<Long>
{
private List<Opportunity> opportunities = new
ArrayList<Opportunity>();
// getters, setters, and other attributes
}
public class Opportunity extends AbstractPersistable<Long>
{
// many class attributes, getters and setters seen in the
binding.xml
}
