The behaviour described would be exactly what would happen if the form
is being submitted by the browser without having run the "onclick"
scripting associated with the button.
Every form has a hidden input field. When a button or link is clicked,
the hidden field's value is updated with the id of the component that
"caused the submit" before the submit actually occurs. On the server
side, the contents of this hidden field is used to determine which
component's actions are to be invoked.
This is why the wiki entry here recommends the approach it does:

I think I'm seeing this exact same thing, and the strange thing is that
the model values look like they get set in both scenarios, but in the
first, the action isn't called. If more than one text field, the action
does appear to execute.

I just noticed some very strange behavior (using IE) regarding buttons:
If I have a single <h:inputText> field and a single <h:commandButton>,
then hitting enter seems to invoke something (because the window
flickers), but the commandButton's action does not get fired.
However, if a add a second <h:inputText> field, even if it has no
associated action, then, if I enter something in the first
<h:inputText>
field and hit enter, the <h:commandButton>'s action gets fired.
Summary:
One (or zero) entry box ==> hitting enter doesn't do anything
two entry boxes (or a table of check boxes) ==> hitting enter
causes the command button's action to fire
This is certainly strange. Just to make sure, I did the following:
Created a screen with just a textArea and a commandButton ==>
hitting enter didn't do anything
Then added an empty inputText ==> hitting enter didn't do
anything
Then added another empty inputText ==> hitting enter fired the
commandButton's action
Does anyone else notice this behavior?

I don't think there is one in MyFaces, but there probably should be
something in tomahawk that can do this. I noticed this one a bit ago:

<http://www.jsftutorials.net/defaultActionTag.html> that does this.
