Disable a4j:status for only h:inputText component but not other components - jsf

I have the following code
<a4j:status id="commonstatus" onstart="#{rich:component('loading')}.show();" onstop="#{rich:component('loading')}.hide();" />
<rich:dataTable id="dTable" reRender="ds">
<rich:column id="name" filterMethod="#{myBean.filterName}">
...
<h:inputText> <a4j:support event="onkeyup" reRender="dTable, ds" ignoreDupResponses="true" requestDelay="700" oncomplete="setCaretToEnd(event);" /> </h:inputText>
...
<rich:datascroller id="ds" reRender="dTable">
...
<a4j:support event="onchange" reRender="dtable, ds" status="commonstatus" />
...
</rich:dataTable>
<rich:modalPanel id="loading" moveable="false" autosized="true">
<h:panelGrid columns="2">
<h:graphicImage value="images/progress.gif"/>
<h:outputText value="Loading..."/>
</h:panelGrid>
</rich:modalPanel>
Problem: Even if I have not specified status="commonstatus" in <h:inputText> I still get the loading image for onkeyup event.
What am I missing here?
Any help would be great.

The <a4j:status> by default applies for all the components in the page that fire an ajax request. However, you can restrict the components that will be caught using the for attribute as stated in the tag component documentation:
for: ID of the AjaxContainer component whose status is indicated (in the format of a javax.faces.UIComopnent.findComponent() call).

You can wrap h:inputText by an a4j:region
or
Set status attribute of the a4j:support to a not existing status id (e.g. status="none")

It's probably a little deprecated, but might be useful if anyone still works with Richfaces 3.3... I defined 2 status components in the common facelet template. One is the main status that is used across application whenever an ajax event fires and it applies to the whole page, and one is "none" status that does nothing (and it must be wrapped in region):
<a4j:status id="main" onstart="(something)" onstop="(something else)" />
<a4j:region>
<a4j:status id="none" onstart="" onstop="" />
</a4j:region>
Whenever I don't want main status to appear, I specify "none" status as Andrey suggested, but the status component actually exists so the warning about non-existing component is avoided.
Don't forget to wrap it in a4j:region, or it won't work correctly - if you have 2 status components in the same region, I think that always the second one will be used, no matter what you put in status tag of your component which fires the request...

p:poll stopped but still fires network call

I have to stop and start a p:poll in JSF using some conditions... I am able to do that by putting the poll in a panelgrid and making the panelGrid rendered... I thought its working since the pollOperationStatus is not called after I made the panelGrid rendered false... When I show it , it restarts as well..
But there is a network call still firing ; which messes up many things ;How to deal it?
<h:form>
My main form
</h:form>
<h:form id="mypollform">
<p:outputLabel id="currentTime" value="#{myBean.counter}" />
<h:outputText value="#{myBean.startPoll}" id="counter11" />
<p:panelGrid rendered="#{myBean.startPoll}">
<p:poll interval="8" widgetVar="poller" autoStart="true"
listener="#{myBean.pollOperationStatus}"
update=":#{p:component('newServerID')},:#{p:component('mypollform')}" />
</p:panelGrid>
</h:form>
Primefaces 7 Documentation says:
Poll can be started and stopped using client side api; Or bind a
boolean variable to the stop attribute and set it to false at any
arbitrary time.
In your case this would be in javaScript:
PF('poller').stop(); or PF('poller').start();
Or bind a boolean bean property the the stop attribute of the p:poll:
<p:poll stop="#{myBean.stopPoller}" interval="8" widgetVar="poller" autoStart="true"
listener="#{myBean.pollOperationStatus}"
update=":#{p:component('newServerID')} :#{p:component('mypollform')}" />
Also beware that component IDs in update attribute are separated by space, not comma.

p:remoteCommand and p:messages with autoUpdate="true" clears messages [duplicate]

I'm using PrimeFaces poll component to refresh some content.
<h:form id="formBsvtt">
<p:messages autoUpdate="true" showDetail="false" />
<p:outputPanel id="panelOut" layout="block">
...
... content to refresh
...
</p:outputPanel>
<p:panelGrid id="panelIn" layout="block">
...
... various input components with validation
...
</p:panelGrid>
<p:poll widgetVar="poll1" autoStart="true" global="false" interval="15"
partialSubmit="true" process="#this" update="panelOut"
listener="#{myBean.myListener}">
</p:poll>
</h:form>
As you can see I'm using messages with autoUpdate=true. My Problem is: In case of validation errors FacesMessages will be shown, but disappear not later than 15 seconds.
Is it possible to prevent poll from clearing FacesMessages without setting messages autoUpdate=false?
My web application is much bigger as code snippet specified above and my intention is not updating messages manually in each possible case!
PrimeFaces 2.x/3.x
This is not natively possible, so a trick is needed. In the rendered attribute of <p:messages>, check if <p:poll> was been triggered and if so, then return false. This way JSF thinks there's no auto-updatable messages component in the component tree during rendering and will therefore ignore it.
If the <p:poll> is triggered, then its client ID appears as javax.faces.source request parameter. So, this should do:
<p:messages ... rendered="#{param['javax.faces.source'] ne poll.clientId}" />
...
<p:poll binding="#{poll}" ... />
(note: no additional bean properties needed)
PrimeFaces 4.x+
All PrimeFaces command components got a new ignoreAutoUpdate attribute which you could set to false to ignore all autoUpdate="true" components in the ajax update.
<p:poll ... ignoreAutoUpdate="true" />
For folks using Primefaces 4.0 and above, the Primefaces team have added an attribute to their ajax aware components to skip triggering components with autoUpdate set to true. So your poll would be
<p:poll ignoreAutoUpdate="true" .../>

JSF action not called OR selectbox value is null

i have another strange JSF problem here... I don´t really know why, but what ever i try to do, i have one out of two problems. Either the action method inside my popupPanel is not (means never) called or it is called, but the value from my selectBox is (always) null. Can´t figure out, what the problem is, but it seems to me, like it´s a XHTML property problem.
Already tried to put the popupPanel outside my h:form (helped me at some other locations...), i also tried to put it outside and put another form into my popup. Beyond that i was trying to change the attachment to parent/form and i changed the execute of the commandButton inside my popup to form/form-id/popuppanel-id and i guess there were some more things i did... but nothing helped.
The Bean is session scoped and i am using Richface 4.0 Final if it does matter at all.
What ever, the XHTML looks like this:
<rich:popupPanel
header="#{label['edit.title']} #{mandateAction.ccService.mandateList[mandateAction.currentIndex].id}"
id="addExternalSystem"
onmaskclick="#{rich:component('addExternalSystem')}.hide()"
domElementAttachment="form" autosized="true" layout="block">
<h:panelGrid columns="2">
<h:outputText value="#{label['login.username']}" />
<h:inputText
value="#{mandateAction.newExternalSystem.username}" />
<h:outputText value="#{label['login.password']}" />
<h:inputSecret
value="#{mandateAction.newExternalSystem.password}" />
<h:outputText value="#{label['mandate.externalSystem']}" />
<h:selectOneMenu
value="#{mandateAction.newExternalSystem.externalSystem}">
<f:selectItems
value="#{creditcardConfigurationService.externalSystems}"
itemLabel="#{system.name}" itemValue="#{system}"
var="system" />
<f:converter binding="#{externalSystemConverter}" />
</h:selectOneMenu>
....
<a4j:commandButton value="#{label['insert.save']}"
action="#{mandateAction.insertNewSystem}"
render="mandate_table" execute="#form"
oncomplete="if (#{facesContext.maximumSeverity==null}) {#{rich:component('addExternalSystem')}.hide();}" />
If your page have any of the required fields kept as empty the submit from the popup panel will not work. In that case include the popup panel inside a form and domElementAttachment="form" , and perform the submit.

Trying to understand why h:commandLink submits through validation and a4j:commandLink doesn't

First of all, i'm using Jsf 1.2...
I have a problem with submitting some values in a form to validation.
Specifically this code segement:
<h:panelGrid columns="4" id="StatusPanel">
<h:outputText value="#{msg.Phone_number_to_send_SMS_to}" />
<h:inputText id="phoneNumber" value="#{general.smsPhoneNumber}" required="true"
requiredMessage="Please enter a valid phone number." />
<a4j:commandLink value="#{msg.Submit_Button}"
reRender="pinCodeDeliveryMsgText, pinCodeDeliveryMsg, pinCodeDeliveryFailedMsg, pinCodeDeliveryMainPanel, LastPinCodeMsg, SendingSMSMSG"
action="#{general.submit}" />
<h:message for="phoneNumber" fatalClass="mandatoryFieldMissing" errorClass="mandatoryFieldMissing" tooltip="true" />
</h:panelGrid>
Which looks like this in the html page:
Whenever I press the submit link, the page doesn't really go through validation, it seems to go with the last successull values instead. The result being that, if the phone number field is left empty, it does nothing and doesn't even render the <h:message> tag.
Actually, I have a workaround fix that looks like this:
<h:commandLink value="#{msg.Submit_Button}">
<a4j:support event="onclick" reRender="pinCodeDeliveryMsgText, pinCodeDeliveryMsg, pinCodeDeliveryFailedMsg, pinCodeDeliveryMainPanel, LastPinCodeMsg, SendingSMSMSG"
action="#{general.submit}"/>
</h:commandLink>
But i'm really curious to know what's the difference between a4j:commandLink and h:commandLink that makes one woirk and the other not.
TnX
Have you tried to set the process attribute of a4j:commandLink to the id of the inputText? Looks like you are just triggering rerendering of some components, so no model update is performed at all.

Form value not passed to Seam bean after a4j reRender

I'm making a webapp in Seam but ran into a problem I can't seem to fix.
I have a JSF form where the customer can select a reservation type through a combobox. Based on the selected value, other form components gets rendered.
For example: the customer selects Hours as reservation type, a panelGroup gets rendered where the customer can select a start- and an end hour. But if the customer would select 'part of the day' as reservation type, a selectOneMenu gets rendered where the customer can select a part of the day (morning, afternoon, evening)
The rerendering well but the values of the components with a rendered conditional won't get passed to the bean. They stay null values.
This is the code i'm talking about:
<s:div id="spot"
rendered="#{selectedProduct.productType.name eq 'Flex Spot'}">
<h:panelGrid columns="2">
<h:outputText value="Reservation Type" />
<h:selectOneMenu value="#{selectedPeriodPart}">
<s:selectItems
value="#{productManager.getAvailableDayPartsSpot()}"
var="daypart"
label="#{daypart.label}"></s:selectItems>
<s:convertEnum />
<a4j:support ajaxSingle="true"
event="onchange"
action="#"
reRender="spot">
</a4j:support>
</h:selectOneMenu>
<h:outputText id="date_spot" value="Date" />
<a4j:outputPanel id="calendar_spot" layout="block">
<rich:calendar value="#{reservation.reservationPeriod.startDate}"
locale="en" cellWidth="24px"
cellHeight="22px"
style="width:200px" />
</a4j:outputPanel>
<h:outputText rendered="#{selectedPeriodPart eq 'DAY_PART'}"
value="Daypart" />
<h:selectOneMenu value="#{selectedDaypart}"
rendered="#{selectedPeriodPart eq 'DAY_PART'}">
<f:selectItem id="si_morning" itemLabel="Morning (6:00 - 12:00)"
itemValue="morning" />
<f:selectItem id="si_afternoon"
itemLabel="Afternoon (12:00 - 18:00)" itemValue="afternoon" />
<f:selectItem id="si_evening" itemLabel="Evening (18:00 - 00:00)"
itemValue="evening" />
</h:selectOneMenu>
<h:outputText rendered="#{selectedPeriodPart eq 'HOURS'}"
value="Hours" />
<h:panelGroup id="hours_spot"
rendered="#{selectedPeriodPart eq 'HOURS'}">
<ui:include src="/includes/reservation/select_hours.xhtml" />
</h:panelGroup>
</h:panelGrid>
</s:div>
Note: The calendar value do get passed back to the bean but the value of this piece of code doesn't (it does if you remove the rendered conditional):
selectOneMenu value="#{selectedDaypart}" rendered="#{selectedPeriodPart eq 'DAY_PART'}"
You need to ensure that the conditionals responsible for the outcome of the rendered attribute are also the same in the subsequent request of the form submit. Because when a component isn't rendered, JSF won't apply the request values them.
In a nutshell, the property behind #{selectedPeriodPart} needs to be the same in the subsequent request. There are several solutions:
Put bean in session scope. Easiest solution, but bad for server memory and client experience (updates would be reflected in multiple tabs/windows in same session).
Pass it through using <h:inputHidden>. Not sure though how this fits in the Ajax/Richfaces picture. Better use <a4j:keepAlive> here.
Use a conversation scope. Seam offers facilities for this.
I fixed it -.- Nothing was wrong with the code I posted.
Because I wasn't able to solve this issue I continued on an other page in the same conversation. I noticed some more strange behaviour: outjection of a variable didn't work etc.
I figured the mistake was in some other part of the code which, after corrected, fixed the whole problem.
Thx for answering guys!
