Hi,
I dont not understand very much about Struts2 inject process but I fixed my
problem extending the compositeActionMapper with the following one:
public class DebugCompositeActionMapper extends CompositeActionMapper {
@Override
@Inject(StrutsConstants.STRUTS_MAPPER_COMPOSITE)
public void setActionMappers(String list) {
if (list != null) {
String[] arr = list.split(",");
for (String name : arr) {
if (container==null) continue; // LINE ADDED
Object obj = container.getInstance(ActionMapper.class,
name);
if (obj != null) {
actionMappers.add((ActionMapper) obj);
}
}
}
}
}
I worked since it do not throw the Null Pointer Exception and it seem during
injection process the function setActionMappers is called twice. One before
the container is set and other after.
I hope it help.
Aloha,
