-------------------------------------

Hi,
I found a solution to this problem. Let me describe my solution; I have the parent and child departments, a recursive ent,ty mapping. In the TaDepartmentHome class I wrote the wire as follows;

@In(create = true)
	TaDepartmentHomeLocal taDepartmentHome;

public void wire() {
		TaDepartment parentDepartment = taDepartmentHome.getDefinedInstance();
		if (parentDepartment != null) {
			if (isIdDefined()) {
				setId(null);
				getInstance();
				getInstance().setTaDepartment(parentDepartment);
				
			}
			else {
				getInstance();
				getInstance().setTaDepartment(parentDepartment);
			}
		}
		else
			getInstance();
	}


public boolean isWired() {
		return true;
	}

It seems to be working, At least I guess So. I welcome the comments from the community.

> I have a reflective 1-n associations e.g. Person child of Person.
> I would like to create a child from the PersonEdit.xhtml created by seam-gen then adapted by hand.
> When I put @PerNestedConversation annotation to my PersonHome the behavior seems to be ok. Each conversation has it's own instance of PersonHome. BUT all of those instances is wired to the same instance of Person (the Entity)...
> I've tried to trace modifications on the "instance" field of Home but it's never set; it should stay to null and then call createInstance() but this never happen because the Person instance is the same as the parent conversation one.
> Update for  Seam 2.1.0SP1: If I ManagedEntityInterceptor is disabled (default configuration now) this problem disappears (and of course it returns if I re-enable it in components.xml). This means that the root cause of this problem is that ManagedEntityInterceptor and PerNestedConversation are incompatible.
