if by non-synchronized component, you mean the 'synchronizeVariablesWIthBinding(){return false;}, then what it really mean is that it won't push <form> elements values from the request to your bound variables.

Inter-Component synchronization are always running, before / after each of RR-Loop. This is to give you the right context (wo-repetition make synchronization even more often).
If in your sub-component, you make direct call to parent().setSomething(...), then this will most likely fail if the parent.something is bound to a variable that will get synchronized later.


I had this problem a while ago, and if I remember correctly, the design of the component interaction was not 'complliant' with WO. So I had to redesign the component interaction.

To help you in more details, I would need more info on your code and/or context of use.

Note that if you want to store temporary RR-Loop value you can always use the context.request.userInfo dictionary, this dictionary will be valid for the whole request. Your sub-component could store value in there and your parent could take it from there whenever it need it.

Hi,

I have a stateless subcomponent with manual synchronization who display some results to the user.
I discovered a problem when I invoke an action on a link under this subcomponent; before my action is invoked, the subcomponent call valueForBinding for synchronization (after the WORepetition inside it called invokeAction). After that WebObjects execute the action invoked by the user and the variables are synchronized again.


This situation cause me some problems because I hold the state of some attributes in the parent component (for the time of the request-response loop); I clear the state when awake is called. I cannot do that if the subcomponent synchronize before some actions are invoked by the user.

Why valueForBinding in the subcomponent with manual synchronization is called before my action is invoked?

Thanks!

Jacky
