I have a rich:calendar on a jsf page like this:
<rich:calendar id="someDate"
name="aName" validatorMessage="wrong format!"
enableManualInput="true" datePattern="dd/MM/yyyy"
value="#{MyBean.someDate}" >
</rich:calendar>
<rich:message id="validationSomeDate" for="someDate"
tooltip="false" showDetail="false">
<f:facet name="errorMarker">
<h:graphicImage id="imgError" value"/someImage.gif" />
</f:facet>
</rich:message>
<rich:tooltip for="validationSomeDate" value="wrong format!"/>
This succesfully validates that the user didn't write some nonsense into the date field like "12456" or something. The problem is, this validation is only triggered when the form is submitted. I would like to have this checked as soon as the date field loses focus, all client-side. Is there a way to do this?
I tried using a
<rich:validator>
tag but I'm using richfaces 3.x and this tag isn't available.
<rich:ajaxValidator event="onblur">
doesn't help either...

The following code in my .xhtml works fine:
<h:commandButton id="btnConsultar"
action="#cadastrarProponenteBean.consultarCnpj}"
value="#{messages.tx_consultar}"
styleClass="btnAcao" />
But, when I add a4j:support:
<h:commandButton id="btnConsultar"
action="#{cadastrarProponenteBean.consultarCnpj}"
value="#{messages.tx_consultar}"
styleClass="btnAcao">
<a4j:support event="onclick" />
</h:commandButton>
the application breaks, I get strange errors, and my validation messages('getFacesContext().addMessage') are not shown.
Since I'm using a4j:support just to show a loading gif when user clicks, any advice on how to fix this problem?
I'm using JSF and RichFaces.
PS: already tried a4j:commandButton instead of h:commandButton but same problems...
You should use <a4j:status> similar to:
<a4j:status id="ajaxstatus" rendered="true">
<f:facet name="start">
<h:panelGroup>
<h:graphicImage value="/images/loading.gif" />
</h:panelGroup>
</f:facet>
<f:facet name="stop">
</f:facet>
</a4j:status>
I have it in template. Loading image is displayed during any long action.
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.
While calling the ValueChangeListener in JSF based on value change in dropdown, it is calling all the ValueChangeListner that are on that page.
There are two valueChangeListener in DataTable, while changing value in one dropdwon the 2nd one also executing.
<t:column id="avlId" styleClass="coltextcenteralign">
<f:facet name="header">
<h:panelGroup>
<h:outputText value="#{bundle['travelLocalAccommodation.title.availability']}" />
<h:outputText value="*" style="color:red" />
</h:panelGroup>
</f:facet>
<t:selectOneMenu value="#{accomDtls.availability}" immediate="true"
valueChangeListener="#{TravelProcessingBB.localAccommodationBB.setAvailableFlag}" forceid="true" id="avl"
onchange="return availabilityAlert('#{accomDtls.prepopulatedFlag}','avl[#{table_count}]')"
styleClass="dropDownStyle" style="width:50">
<f:selectItem itemValue="Y" itemLabel="Yes" />
<f:selectItem itemValue="N" itemLabel="No" />
</t:selectOneMenu>
</t:column>
The value change alone won't automatically call the valueChangeListener. You need to submit the form as well. A commonly used "hack" is to call form.submit() using JavaScript during the onchange event. This will however submit the entire form. Truly the valueChangeListener will be triggered for all changed fields of the form.
To fix this in JSF 1.x, you need to hassle somewhat with the immediate attribute to skip all other form components from validating and with component binding so that you can properly get/set the other component's value. Long story short, I ever wrote an article about that: populate child menus in JSF 1.2.
In JSF 2.0, this is however easier to achieve with help of <f:ajax> tag. If you're really using JSF 2.0 (your current question doesn't indicate that), then let me know if you need an example.
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.
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!
