I have filed an enhancement request for this. I wanted to implement a
comprehensive logging system for user testing so you can see the
exact path a user took to cause the application to break. Currently
you can only see the page sequences returned that occurs and not the
actions that invoke it. For example if you are doing something that
doesn't require the page to reload, like adding to a selection, you
may return the same component, NullComponent, that is empty. If you
return the same component for the deselect method, then there is no
way to determine whether the user selected or deselected.
What I asked for in the bug report was for a method to get the target
WOAssociation for a request, so that if there is an action binding,
you can log out the name of the action.
Make sure you file something similar so that the engineers see it is
a requested feature.

Hi!
I'm trying some AJAX stuff, and I need to work with the element
IDs of the objects. While building the page, i just ask the
context what is the current elementID(). But how do I do the
reverse operation? How can I ask the context what is the object
associated with some ID?
Short answer: can't.
Slightly longer answer: while there might be some way, deep down in
private API, I've never seen it. This is not how WO works. During
the invokeAction phase the tree of elements is traversed, and
invokeAction is called on each one. Each element can do
(a) nothing
(b) whatever it pleases :-)
(c) check and see if the action is for it:
if (url.elementId == context.elementId) {
// Yippee, it's for me!
}
You can also check url.elementId.startsWith(context.elementId) to
see if the action is for one of your child elements.
