Hello Mike,
I think I understand... just to make sure:
-I've got a parent component let's call it Parent
-I've got a child component let's call it Child
In Child and Parent, I've got a status variable with its accessors.
Inside Child, in the WOD, I'm calling Parent and bind status(Child)
to status(Parent).
My issue isn't a performance one, I need my status in Parent to be
updated when I change status in Child (throw an action in child).
Actually when I trigger my action in Child, it changes the status in
Child, but then it is set back to the value in Parent (which I though
would be updated because of the status = status binding).
How could I make sure the status in Parent is updated according to
the status in Child?
Do I have to set the status variables in both Parent and Child?
Thanks
Xavier
syncBindings only applies to the bindings INTO the component as
defined in a WOD file that uses it. If you notice in the stack trace:
at com.webobjects.appserver.WOComponent.pushValuesToParent
(WOComponent.java:547)
so this is actually bindings pushing back UP from a child component
inside. What's happening is that in the WOD file for this
component, you are binding "status" into another component, and
that component is pushing values back up, which in turn is calling
setStatus again. This, however, happens a million times a request
and is pretty fast. If setStatus is expensive in your component,
then you can do something like:
private int _status;
public void setStatus(int status) {
if (status != _status) {
// do stuff
}
}
