What should I do if synchronizeVariablesWithBindings is true? (or
should I just implement it to be false for the parent component in
this case?)

If your component's synchronizeVariableWithBindings(0 returns false
then the component should use setValueForBinding() to set the value

Hey guys (and gals),
I'm trying to figure out how to propagate an object selection from
a child component up to it's parent (and down to another child
component, but that should just be a simple binding).
My component hierarchy (a bit simplified) looks like this:
<ParentComponent>
<Component1>
<AjaxUpdateContainer>
Object1 list <= has an action to select an Object1
</AjaxUpdateContainer>
</Component1>
<Component2 selectedObject1="selectedObject1">
<AjaxUpdateContainer>
selectedObject1 detail
Object2 list <= has an action to select an Object2
</AjaxUpdateContainer>
</Component2>
<AjaxUpdateContainer>
<wo:if selectedObject2>
<Component3 selectedObject2="selectedObject2">
<AjaxUpdateContainer>
selectedObject2 detail
</AjaxUpdateContainer>
<Component3>
</wo:if>
</AjaxUpdateContainer>
</ParentComponent >
Now, somehow I got the selection and detail display of Object1
working just fine. But...now that I'm trying to get the selection/
detail display of Object2 working, I can't seem to get it to work
right.
All of the components involved are currently just using simple
public variable bindings (yeah, I know, I should be using accessors
for better encapsulation...), with the "selection" methods in
Component1 and Component2 using parent.setValueForBinding to set
the selected object in the parent component.
Is it just a fluke that the selection of Object1 is working?
Should I be using non-synchronized bindings for my parent
component? Or is there something else I'm missing (or a better way
to do this)?
