Yes the issue is that you use a command button which in case of a single
button maps automatically to input type="submit" if you hit enter
the ajax request is issued and subsequently parallely the full submit is
issued as well.
You can resolve that by using commandlinks or <h:commandButton
type="button"> which should resolve the auto enter issue introduced by
the input type="submit".
The problem with the error is not a bug but an xhr request issued
asynchronously then a page refresh triggered at the same time which is
more a problem of the spec relying on parallel xhr requests. MyFaces
then correctly issues an http error due to the timing issue triggered
because of the xhr request having failed due to the subsequent refresh
issued. But as usual with those timing problems they occur depending on
the current state of the issue, hence in a non reproducable manner.
So the final behavior after fixing is
change + enter -> onchange
button press -> action

Hi,
I have the following example:
<h:outputLabel for="val1" value="Value1"/>
<h:inputText id="val1"
value="#{myBean.val1}"
valueChangeListener="#{myBean.val1ChangedListener}">
<f:ajax render="myText" event="change" />
</h:inputText>
<h:outputText id="myText" value="#{myBean.val1}"/>
<h:commandButton id="button" value="submit" action="#{myBean.action}"/>
Now I fill out the input field and directly press Enter for submit or
click submit button without leaving the input field before. Now two
requests are send parallel (page submit and ajax value change event).
The problem is I found four different behaviours which comes random
(with firefox):
1.) 1. request: value change listener is called. 2. request actions is
called (that's what I expected)
2.) 1. request value change listener is called. but the action request
is missing.
3.) 1. action request get's in an fires the value change event and calls
the action. but than this message pops up:
"httpError-httpError-Request failed- Note, this message is only sent,
because project sage is development and no other error listeners are
registered"
4.) 1. request value change lister is called. 2. request also value
change listener is called and than the action is called. the message
above also pops up.
In IE sometimes the action is called, sometimes not. The value change
listener is always called. But this error dialog (like in firefox) is
never shown.
Is there any explanation? How could I force a fix behaviour?
Thx for help.
Marcus
