I have a chips component and I want to add a button beside it and use this button to add values to this component.
My draft code is:
<p:outputPanel>
<p:chips id="TextToChips" value="#{myBean.myList}" unique="true" />
<p:button id="addButton">
<p:ajax event="click" process="TextToChips" update="chips" delay="300" listener="#{myBean.method}" />
</p:button>
</p:outputPanel>
I want to use the method addItem(value), which is listed in the documentation. So how can I use that if my principle is possible?

I tried to use draggable component https://www.primefaces.org/showcase/ui/dnd/draggable.xhtml for inputTextArea component but it does not work for me. Do you know any workarounds for making input components draggable?
My code:
<p:outputPanel>
<p:inputTextarea id="test">
</p:inputTextarea>
</p:outputPanel>
<p:draggable for="test" containment="parent" />
I don't have any errors in console. But drag function does not work as it work for p:panel, for example.
try to wrap the component in a panel and assign "for" to that panel.
<p:outputPanel>
<p:panel id="test">
<p:inputTextarea />
</p:panel>
<p:draggable for="test" containment="parent"/>
</p:outputPanel>
I would like to update a component without processing it. I use a binding get the value of a checkbox and decide if the other component should be rendered. Unfortunately, the update? or the binding? doesn't work as i would.
<p:selectBooleanCheckbox id="isPercentage" value="#{myBean.isDiscountInPercentage}"
label="Percentage" binding="#{discountInPercentage}">
<p:ajax process="" update="outpDiscountValue" />
</p:selectBooleanCheckbox>
<p:outputPanel id="outpDiscountValue">
<h:outputLabel value="$" rendered="#{!discountInPercentage.value}" />
<h:outputLabel value="%" rendered="#{discountInPercentage.value}" />
</p:outputPanel>
hi we are using along with a4j tag.
here we are retrieving data from database after a click of button. even though the data is available in server, it will not display over view. After manual refresh of web page will lead to data diplay.
here is code snippet
.... some code here
<rich:tab id="menu5" label="Recall">
<ui:include src="/pages/mctrans/reCallMcifTrans.xhtml" />
</rich:tab>
reCallMcifTrans.xhtml contains below code
<h:commandButton type="button" id="reCallbutton1" value=" Search "
styleClass="commandExButton">
<a4j:support event="onclick" id="ajsf12"
oncomplete="javascript:alert('Search Completed');javascript:document.body.style.cursor='default';"
action="#{mcifRecallTransBean.reCallSearch}" reRender="reCallgrid1" />
</h:commandButton>
It looks like you're working with RichFaces 3.3. So, you don't need a <h:commandButton with <a4j:support> because you can use <a4j:commandButton> that already does this. You can refactor your code to this:
<a4j:commandButton type="button" id="reCallbutton1" value="Search"
styleClass="commandExButton"
action="#{mcifRecallTransBean.reCallSearch}"
reRender="reCallgrid1"
oncomplete="javascript:alert('Search Completed');javascript:document.body.style.cursor='default';" />
Make sure your reCallgrid1 component is available in the same <h:form> of the <a4j:commandButton>.
Since you also want to add a Wait while searching the data behavior when the button is clicked, you can use <a4j:status> along with the <a4j:commandButton> as shown in the <a4j:status> demo. Here's a basic example:
<a4j:commandButton type="button" id="reCallbutton1" value="Search"
styleClass="commandExButton"
action="#{mcifRecallTransBean.reCallSearch}"
reRender="reCallgrid1" />
<!-- Note that there's no oncomplete in this case -->
<a4j:status for="reCallbutton1">
<f:facet name="start">
<h:graphicImage value="/res/images/wait.gif"/>
</f:facet>
</a4j:status>
At last but not least, you should switch your managed bean to request scope and use RichFaces powerful <a4j:keepAlive> in order to simulate JSF 2 #ViewScoped. You can even use it in form of annotation on your managed bean (no additional configuration):
#KeepAlive
public class McifRecallTransBean {
//managed bean code here...
}
When you are using request parameters inside the bean, you need to pass them again with your action :
<h:commandButton type="button" id="reCallbutton1" value="Search" styleClass="commandExButton">
<a4j:support event="onclick" id="ajsf12" oncomplete="javascript:alert('Search Completed');javascript:document.body.style.cursor='default';" action="#{mcifRecallTransBean.reCallSearch}" reRender="reCallgrid1" />
<f:param name="param1" value="#{param['param1']}" />
<f:param name="param2" value="#{param['param2']}" />
</h:commandButton>
Hi I followed this code but my logout button is not at the right side of menubar.
sample from PF
here is my xhtml page
<h:body>
<p:menubar autoDisplay="false">
<p:menuitem value="Home" url="/index.jsf" />
<p:submenu label="Maintenance" >
<p:menuitem value="Course" url="/views/course/list.jsf" />
<p:menuitem value="Student" url="/index.jsf" />
</p:submenu>
<f:facet name="options">
<p:commandButton type="button" value="Logout" icon="ui-icon-extlink" />
</f:facet>
</p:menubar>
</h:body>
You should use a style="float: right;" inside the button or include the property into your css stylesheet.
I am able to get the logout to the right by using the below code
<f:facet name="options">
<p:commandButton type="button" value="Logout" />
</f:facet>
Use: inputText style="margin-right:10px" in the facet... Surely will work.
It will work only in primefaces 3.5 change to primefaces 3.5 and it will work you can verify this at primefaces link primefaces blog
For more details go to primefaces showcase page primefaces showcase menubar sample page for sample code this code is from that sample page
<f:facet name="options">
<p:inputText style="margin-right:10px"/>
<p:commandButton type="button" value="Logout" icon="ui-icon-extlink" />
</f:facet>
if your using prime-faces 5, then it should work. Try to browse your application in a web browser instead of the IDE your using to code. Because It's not appear as we expected in the IDE but it's work fine in a web browser. You can also use styleClass inside the tag. insert styleClass="margin-riight:10px" inside the button tag
I'm trying to display validation messages everytime the user clicks on a radio button.
This only works when I click on the submit button, but not when I click on the radio button:
<h:form id="form">
<p:panel id="panel">
<ui:repeat value="#{questionsBean}" var="question">
<h:panelGrid columns="3" style="margin-bottom:10px" cellpadding="5">
<h:outputText value="#{question.questionText}" />
<p:selectOneRadio id="question" value="#{question.response}"
validator="#{question.validate}" required="true">
<f:selectItem itemLabel="Yes" itemValue="Yes" />
<f:selectItem itemLabel="No" itemValue="No" />
<p:ajax update="msgQuestion" event="change"/>
</p:selectOneRadio>
<p:message for="question" id="msgQuestion" />
</h:panelGrid>
</ui:repeat>
<p:commandButton id="btn" value="Save" update="panel" partialSubmit="true"/>
</p:panel>
</h:form>
The HTML DOM change event is the wrong event when you want to listen on whether the radio button (or checkbox) is clicked. You should be using the click event for this.
The value of the radio button (and checkbox) basically never changes. It has always the same value. The question is more whether that value will be sent to the server side or not. This is determined by the "checked" state which is usually triggered by the DOM click event.
The actual behaviour of the change event on radiobuttons/checkboxes is dependent on the webbrowser used. The behaviour is particulary inconsistent in the IE browser. It not only depends on the version used, but also in the rendering mode used (quirks mode vs standards mode). Perhaps you were actually using IE while testing.
The default event type of the PrimeFaces <p:ajax> (and the standard JSF <f:ajax>), which is valueChange already automatically covers this:
<p:ajax update="msgQuestion" event="valueChange" />
This will autogenerate the right change event handler in text inputs and dropdowns and the click event handler in radiobuttons and checkboxes.
But as said, it's the default event type already. Just omit it altogether.
<p:ajax update="msgQuestion" />
