- Outjection and component instantiation question

- Outjection and component instantiation question

2007-05-07       - By zzzz8

 Back
I think I may have a misconception of some of the intricacies of outjection and
Seam component instantiation.  I have a Seam component that is created by Seam
via the @(protected)(create=true) annotation.  Unfortunately, I cannot seem to inject
another Seam component into this component.  Here's what I'm doing:

Seam component 1

 | @(protected)("comp1")
 | @(protected)
 | public class MySample1Bean implements MySample1 {
 | ...
 |
 | @(protected)
 | Connection connection = null;
 | ...
 | public void myMethod() {
 | ...
 | connection = ...;
 | ...
 | }
 | }

Seam component 2

 | @(protected)("comp2")
 | @(protected)
 | public class MySample2Bean implements MySample2 {
 | ...
 |
 | @(protected)(create=true) // I've also tried @(protected)(create=true, required=false)
 | MySample3 comp3 = null;
 |
 | @(protected)
 | Connection connection = null;
 | ...
 |
 | }

Seam component 3

 | @(protected)("comp3")
 | @(protected)
 | public class MySample3Bean implements MySample3 {
 | ...
 |
 | @(protected) // I've put @(protected)(required=false) here, too just so component gets created
 | Connection connection = null;
 |
 | ...
 |
 | }

I have a page where comp1 is called.  The user then invokes an action method
which then navigates the user to another page, where comp2 is accessed.  BTW, I
have it on my pages.xml file that a long running conversation gets started (i.e
. using <begin-conversation> when the page is invoked) for the page that calls
comp2.  The Seam component comp3 gets created in comp2 because of the @(protected)
(create=true) annotation.  However, when comp3 is created, I'm expecting the
connection context variable to be outjected to comp3.  Unfortunately,
connection is always null in comp3.  Interestingly, connection is non-null in
comp2.  What's going on here and what am I doing wrong?
