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 am working with javaEE, and for my project i used TreeTable and BlockUI to block this table, but i want to make a button appear even if it is blocked
<p:blockUI block=":form:treeTable" widgetVar="tbd" blocked="#{ManagedBean.condition}" />
<h:form id="form">
<p:treeTable id="treeTable" ... >
<f:facet name="header">
<p:commandButton value="SomeAction" actionListener="#{ManagedBean.someAction}" update=":form"/>
</f:facet>
in my example i want to make my commanbutton appear as available even if i use BlockUI
thantk you
This is not a functional problem but a design problem.
As is, the CommandButton is part of the TreeTable, so the CommandButton must be blocked if the TreeTable is blocked.
For sure Raziels answer will work, but a clean solution would be to move the button out of the TreeTable.
<h:form id="form">
<p:commandButton
value="SomeAction"
actionListener="#{ManagedBean.someAction}"
update=":form"
/>
<p:treeTable
id="treeTable"
...
/>
<p:blockUI
block=":form:treeTable"
widgetVar="tbd"
blocked="#{ManagedBean.condition}"
/>
</h:form>
I already Solved this problem by using z-index:99999 inside a style tag
so your code should be like :
<p:blockUI block=":form:treeTable" widgetVar="tbd" blocked="# {ManagedBean.condition}" />
<h:form id="form">
<p:treeTable id="treeTable" ... >
<f:facet name="header">
<p:commandButton value="SomeAction" style="z-index: 99999" actionListener="#{ManagedBean.someAction}" update=":form"/>
</f:facet>
I have the maven dependency for omnifaces for version 1.11 (as my target is JDK 1.6). Richfaces 4.5.6 final, myfaces 2.2.8. And, against a viewscoped bean I have got this xhtml:
<ui:define name="content">
<f:loadBundle basename="au.com.erb.facility.ui.facility"
var="property" />
<o:highlight styleClass="error" />
<h:panelGrid columns="2">
<rich:validator event="change">
<o:outputLabel value="#{property.absClientNumber}" for="input1" />
<h:inputText id="input1"
value="#{facilityBean.facilityForEdit.alternateKey.absClientNumber}"
label="ABS Client Number" />
<o:outputLabel value="#{property.facilityid}" />
<h:inputText
value="#{facilityBean.facilityForEdit.alternateKey.facilityId}"
label="Facility Id" />
<h:outputLabel value="#{property.rfsAccountGroup}" />
<h:inputText value="#{facilityBean.facilityForEdit.rfsAccountGroup}"
label="RFS Account Group" />
<h:outputLabel value="#{property.rfsAcctCustomerNumber}" />
<h:inputText
value="#{facilityBean.facilityForEdit.rfsAcctCustomerNumber}"
label="RFS Account Customer Number" />
<h:outputLabel value="#{property.rfsAcctLedger}" />
<h:inputText value="#{facilityBean.facilityForEdit.rfsAcctLedger}"
label="RFS Account Ledger" />
</rich:validator>
</h:panelGrid>
</ui:define>
<!-- Buttons that performs actions on a selected record -->
<!-- or navigate to a relevant screen -->
<ui:define name="buttons">
<h:commandButton id="submitButton" value="#{property.submitLabel}"
action="#{facilityBean.save}" styleClass="wideButton"
onclick="#{rich:component('progressWaitModalPanel')}.show()" />
<h:commandButton id="closeButton" value="#{property.closeLabel}"
action="#{facilityBean.close}" styleClass="wideButton"
immediate="true" />
<rich:popupPanel id="progressWaitModalPanel" modal="true">
<f:facet name="header">
<h:outputText value="Processing your request ...." />
</f:facet>
<h:panelGrid columns="1"
style="width: 100%; border-width: 0px; text-align: center;">
<h:outputText value="Please wait..." styleClass="dataValueStyle" />
</h:panelGrid>
</rich:popupPanel>
</ui:define>
The result is nothing. No higlight. No clue what's going on. Have I missed any installation step? I have the css and xmlnamespace in place. Anything else?
I tried to add required="true" as it was shown in the example, but that did not work either. Not sure whether it is due to richfaces bean validation issue.
The <o:highlight> works server side, based on a.o. UIInput#isValid() in JSF component tree. The <rich:validator> works client side and doesn't manipulate JSF component tree.
This indeed doesn't go well together.
I briefly looked into the HTML/JS code of the <rich:validator> showcase and it appears that they don't add a marker style class to the input elements when it's invalid (e.g. PrimeFaces does), so it's going to be hard to write a workaround when continuing the <rich:validator> approach.
You've basically following options:
Maunally write an oncomplete script which finds the validation error messages and then finds the associated inputs and then set the desired marker style class on it.
Report an issue to RichFaces guys and ask them to add a marker style class to invalid inputs via <rich:validator>, so you could style them individually.
Drop <rich:validator> and replace it by server side validation via <f:ajax>.
I'm seeing a strange behaviour with Primefaces (4.0) related to Panels whose collapsed-attributes are bound to a property in a backing bean. Updating the state works fine so the panel collapses/expands correctly when the value of the backing bean changes.
The problem is: I have some p:Dialogs that can be opened to enter some additional/optional information. After closing the dialog, the panel fails to expand/collapse when changing the value. Strangely, other attributes bound to the same property get updated like before.
Example:
XHTML of two panels whose collapsed Attribute is bound to a property. Note that the disabled-attribute of the checkboxes are bound to the same property and still get updated after the dialog is closed.
<p:panel id="panel1" style="width:80%;" toggleable="true" collapsed="#{!bean.panel1.enabled}" widgetVar="panel1Var">
<f:facet name="header">
<p:outputLabel value="Panel1"/>
<p:selectBooleanCheckbox id="p1_enabled" style="margin-left:20px;" disabled="#{bean.panel2.enabled}" value="#{bean.panel1.enabled}">
<f:ajax render="panel1 panel2" />
</p:selectBooleanCheckbox>
</f:facet>
<p:panelGrid columns="2" style="width:100%;" columnClasses="input-col1,input-col2">
<!-- omitted -->
</p:panelGrid>
</p:panel>
<p:panel id="panel2" style="width:80%;" toggleable="true" collapsed="#{!bean.panel2.enabled}" widgetVar="panel2Var">
<f:facet name="header">
<p:outputLabel value="Panel2"/>
<p:selectBooleanCheckbox id="p2_enabled" style="margin-left:20px;" disabled="#{bean.panel1.enabled}" value="#{bean.panel2.enabled}">
<f:ajax render="panel1 panel2" />
</p:selectBooleanCheckbox>
</f:facet>
<p:panelGrid columns="2" style="width:100%;" columnClasses="input-col1,input-col2">
<!-- omitted -->
</p:panelGrid>
</p:panel>
XHTML somewhere else on the same page which opens a dialog:
<p:commandLink id="contactbutton" onclick="PF('contactextended').show();">
<h:outputText value="Extended" />
</p:commandLink>
The dialog is configured like this:
<p:dialog widgetVar="contactextended" modal="true" width="600px" height="500px" showEffect="fade" hideEffect="fade" resizable="false" draggable="false">
The backing bean is a straightforward bean with properties and getters/setter which obviously work. Is there a problem in my implementation? Any ideas how to work around this issue?
Thanks in advance!
Fixed this by myself. The solution seems to be to add process="#this"to the commandLink. I am still not sure what the underlying problem is/was, but at least it doesn't get triggered anymore.
I have a JSF page using richfaces with a few help buttons like this:
<rich:componentControl for="panelHelp" event="oncomplete" operation="show" />
The panel called is this:
<rich:modalPanel id="panelHelp" minHeight="250" minWidth="500"
keepVisualState="true" resizeable="true" moveable="true">
<f:facet name="header">
<h:outputText value="Help" />
</f:facet>
<f:facet name="controls">
<h:commandLink value="">
<h:graphicImage value="/close2.png" title="Close" />
<rich:componentControl for="panelHelp" event="onclick" operation="hide" />
</h:commandLink>
</f:facet>
<h:panelGrid columns="1" width="100%">
<h:outputText escape="false" id="txtHelp"
value="#{msgHelp}" style="width: 100%; height: 190px" />
</h:panelGrid>
</rich:modalPanel>
However, whenever I press the button to close the panel, it reloads the whole page, instead of simply hiding the panel.
Am I doing something wrong, or is there a better way to do this?
I'm using richfaces version 3.3.3
Use a4j:commandLink instead of h:commandLink and provide an a4j:support as well. This should fix the problem.
It's reloading the entire page because of your use of the <h:commandLink/>, which is going to trigger the entire JSF request processing lifecycle. To get your desired results you don't need the command link component. All you really need is:
<f:facet name="controls">
<h:graphicImage id="closeButton" value="/close2.png" title="Close" />
<rich:componentControl attachTo="closeButton" for="panelHelp" event="onclick" operation="hide" />
</f:facet>
What we're doing here is firing the <rich:componentControl/> on click of the image; there's no need for a link. I'm assuming you're using Richfaces 3.X. (RF 4.X has deprecated the attachTo attribute)
Above answer will work in Richfaces 3.x, If you are using Richfaces 4.x then the given code will work.
<f:facet name="controls">
<h:graphicImage value="/close2.png" >
<rich:componentControl target="closeButton" operation="hide" event="click" />
</h:graphicImage>
</f:facet>
Add disableDefault="true" attribute to your rich:componentControl to disable default behavior of the link on click.
I have a problem that a I couldn't solve. When I click first time on a a4j:commandButton there is not action. The second and following time it works perfectly. I have read about this problem however I have not clear the solucion.
I am new, and I have find this solucion: (h:commandButton/h:commandLink does not work on first click, works only on second click) however I do not know where should I introduce the script code.
I have found this: however I think is an old jsf version:
(https://community.jboss.org/thread/165031)
And I have tried to repare it with: https://community.jboss.org/wiki/ProgrammaticControlOfPartialProcessingInRichFaces4. However, I have not been success
If someone could explain me the #BalusC solution step by step, it could be really hepful
Thanks very much:
My code is: (everything in the same file)
<ui:define name="table">
<h:form id= "formListCompanies">
<a4j:outputPanel id="tablePaneRegion">
<rich:extendedDataTable ....
<rich:column sortable="false" width="100%">
...
<a4j:commandLink id="editCmd" styleClass="no-decor" render="editGrid, editPane"
execute="#this" oncomplete="#{rich:component('editPane')}.show()">
<a4j:param value="#{it.index}" assignTo="#{myBean.currentIndex}" />
<f:setPropertyActionListener target="#{myBean.selected}" value="#{mypojo}" />
</a4j:commandLink>
....</rich:column>
....
<rich:popupPanel id="editPane" header="#{...}" domElementAttachment="body"
moveable="true" modal="true" resizeable="false" autosized="true"
onshow="focus(#{rich:component('name')});">
....
<!-- h:Inputtext ..-->
<h:panelGrid columns="2">
<a4j:commandButton value="#{'save'}" action="#{myBean.edit}"
render="dataTable" execute="editPaneRegion" />
<a4j:commandButton value="#{...}"
onclick="#{rich:component('editPane')}.hide(); return false;" />
</h:panelGrid>
</h:form>
</a4j:outputPanel>
</rich:popupPanel>
What I have already tried is to take out the h:form id= formListCompanies, and put there a h:panelgrid and a h:panelgroup
Is the problem related to the doble clicking issue? Am i in the right way?
rerender panel and form (form state lost error in jsf spec)... render="richPanelMantenimientoTipoVisualAjaxWebPart,frmMantenimientoTipoVisual"
