Remember I said this is a simplified, reproducible case of what I
actually have. I'm using an AjaxObserveField to observe several
input elements (text fields and pop-ups). I think it's more elegant
to wrap them with a single AjaxObserveField and not worry about
giving the input fields an ID.
Then I have several ajax update links for next, previous, first,
last, etc. They all update the update container and have a specific
action associated with them. For example, my update link for next
has action = "$goNext".
Anyways, back to the original problem, the action of the
AjaxUpdateLink is not called when I click on them if they are placed
inside the AjaxObserveField. If I move them outside the
AjaxObserveField then they work okay.
I'd like to know if this is a bug before I file a Jira. :-)
Might as well just file it. It is either a bug or something that
should receive an exception.

From the javadoc:
If you do NOT specify an observeFieldID, all of the form fields
contained within this component will be observed for changes instead.

Some will correct me If I'm wrong, but I think you are using
AjaxObseveField wrong:
the way to use it is to supply an observeFieldID = "IDofElement"
and it will look for changes on the element with ID "IDofElement",
invoking the $action and/or updating the $updateContainerID when
there's a change.

Is there a reason why my action would not get called when I use
the AjaxUpdateLink's in a configuration like this:
<wo:form>
<wo:AjaxUpdateContainer id="Foo">
<wo:AjaxObserveField updateContainerID="Foo" elementName="span">
<wo:textfield value="$foo"/>
<wo:AjaxUpdateLink action="$doSomething" string="Do It"/>
</wo:AjaxObserveField>
</wo:AjaxUpdateContainer>
</wo:form>
This is a simplified version of what I have just to demonstrate
what I'm talking about. In order for my AjaxUpdateLink's action
to get called I have to move it outside the AjaxObserveField like
this:
<wo:form>
<wo:AjaxUpdateContainer id="Foo">
<wo:AjaxObserveField updateContainerID="Foo" elementName="span">
<wo:textfield value="$foo"/>
</wo:AjaxObserveField>
<wo:AjaxUpdateLink action="$doSomething" string="Do It"/>
</wo:AjaxUpdateContainer>
</wo:form>
