Hi All
THE JSF livecycle is like this
Faces Request -> Restore View -> Apply Request Values (call all the
setters) -> process events -> ...
There are two possible ways how to configure to submit a form: With a
button(and its action) or with the javascript onchange property on any
element.
But the JSF Livecycles are DIFFERENT!!!
I got a setter and an event called updater. The updater uses the
variable "currentKpiGroup" which is set by the setter.
By button:
==========
<h:selectOneMenu
id="selectedKpiGroup"
value="#{flowScope.KPIBrowserBean.currentKpiGroup}">
<f:selectItems value="#{flowScope.KPIBrowserBean.kpiGroups}" />
</h:selectOneMenu>
<h:commandButton action="#{flowScope.KPIBrowserBean.kpiGroupChanged}"
value="Change" styleClass="button" />
By onchange-property:
=====================
<h:selectOneMenu
id="selectedKpiGroup"
value="#{flowScope.KPIBrowserBean.currentKpiGroup}"
valueChangeListener="#{flowScope.KPIBrowserBean.kpiGroupChanged}"
onchange="submit()">
<f:selectItems value="#{flowScope.KPIBrowserBean.kpiGroups}" />
</h:selectOneMenu>
So, everything works fine if I use the button to submit the form(console
oputput):
SETTER currentKpiGroup grp: 3
UPDATER(event) currentKpiGroup: 3
The setters are called before the events.
If I use the onchange property, the console output is this:
UPDATER(event) currentKpiGroup: 2
SETTER currentKpiGroup grp: 3
my application performs wrong because of the old
value(currentKpiGroup=2).
The event is process before the new value(currentKpiGroup=3) are set.
Does sombody know anything about this behavior? I need to submit the
form by onchange...
I'm looking forward to your answers!
Thanks,
Remo
