Hi all.
I am using Struts 2.2.1; and, I have the following concern: I have an object A which has reference to three other objects: B, C, D. In my JSP I make reference to properties in all A, B, C and D. I call an action which implements the ModelDriven Interface.
However, the only properties that gets populated are the simple properties of A. I was under the impression that ModelDriven would populate the entire object graph for you, namely, all the properties of A, B, C and D. I have tested various notation in my JSP including:
Parent.Child.Property
Child.Property
Property
No luck. I believe that it is possible to populate an object graph based on ModelDriven. Am I correct in thinking this? Could you please offer some advice if I am correct in thinking this?
Thanks.

That's right. Here's a working example I just put together:
Model and action classes:
Action configurations in struts.xml
JSP pages
Do you have the appropriate getter/setter methods implemented in your domain model classes? Are you using a custom interceptor stack?
Best regards
Dejan

Since you have implementet ModelDriven,you do not need write "aaa.bbb.bid" in your select tag.
"bbb. bid" is enough.
