JSON Plugin to Include Parent Action's Properties
Hey,
How do I include some of a parent action's properties in the JSON result of
an action? In the following example, I'd like MyAction2's JSON result
includes name1 and name2 from MyAction1 too.
public abstraction class MyAction1 extends ActionSupport {
protected String name1;
protected String name2;
....
}
public class MyAction2 extends MyAction1 {
...}
Thanks!
Daniel

It's a property on action definition.
For the example:
<action name="StatusDocumento" method="list" class="fatura.controller.StatusDocumento">
<result name="success">statusDocumento/list.jsp</result>
<result name="json" type="json">
<param name="ignoreHierarchy">false</param>
<param name="excludeProperties">dao</param>
</result>
</action>

There is also a includeProperties that you can use, to select only the properties you want to expose through json.

Thanks, everybody.
I tried ignoreHierarchy, but got a Java reflection exception. Even if it
worked, it would have include too many things I don't want. According to
the documentation, it "... serialize properties in all base classes (up to
Object) ".
I could try to use the excludeProperties parameter, but there will be too
many properties to exclude. In addition, if the super class is modified to
have additional properties, it may break the JSON code without my knowledge.
What I really wish is to be able to selectively include supper class
properties, like syntax like"MyAction1.name1, MyAction2.name2".
Cheers,
Daniel

Then create an inner class within your Action that contains just the
information youbwant to include in the JSON and set it as the base object
to marshal.
