[jbossseam-issues] [JBoss JIRA] Created: (JBSEAM-4438) Circular Injection causes Seam Injected variables to be null before invocation is complete
Circular Injection causes Seam Injected variables to be null before invocation is
complete
------------------------------------------------------------------------------------------
Key: JBSEAM-4438
URL: https://jira.jboss.org/jira/browse/JBSEAM-4438
Project: Seam
Issue Type: Bug
Components: Core
Affects Versions: 2.1.0.GA
Environment: I've only tested this on 2.1.0.GA so far, but I can't see
anything in the release notes that would have fixed this in other versions. I will test in
2.2.0.GA soon.
Reporter: Tim Evers
OK, so If we have Seam bean A and Seam bean B and Seam bean C;
A {
@In
B b
@In
C c
public void doSomethingWithBs() {
b.doSomething(); //IMPORTANT LINE 1
c.doSomethingDifferent(); //IMPORTANT LINE 2
}
public MyDomainObj getCurrentObj() {
return myVar;
}
}
B {
@In
A a;
public void doSomething() {
process(a.getCurrentObj); //LINE THAT CAUSES BUG
}
private void process(MyDomainObj x) {
....
}
}
OK, so the situation is this
on line marked with //IMPORTANT LINE 1 all injected variables are set. The method in Seam
bean B gets executed and after that line of code has executed and the program is about to
execute line marked with //IMPORTANT LINE 2 the injected variables are null. Thus I get a
null pointer exception on variable c;
See my forum reference link for a more detailed example.
