I am creating a demo project using primeface 3.3 and JSF, in which if a user doesn't fill a required field then it should show a message. Here is my code:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:p="http://primefaces.org/ui">
<f:view contentType="text/html">
<h:head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1" />
<title> growl</title>
</h:head>
<h:body>
<h:form>
<p:growl id="growl" showDetail="true" sticky="true" />
<p:panel >
<h:panelGrid columns="3">
<h:outputText value="Your Name: *" />
<p:inputText value="#{someBean}" required="true" label="Name" requiredMessage="User Name Requireds"/>
<h:messages style="color:red;margin:5px;" />
</h:panelGrid>
<p:commandButton value="Save" action="success" />
</p:panel>
</h:form>
</h:body>
</f:view>
</html>
when clicking to save button without filling user name it doesn't show the required message
The <p:commandButton> sends by default an ajax request wherein by default the entire form is executed (as in process="#form"), but by default actually nothing will be updated (as in update="").
If you want to update the UI on complete of the ajax request, then you need to explicitly specify the update attribute. For example, this updates the entire form:
<p:commandButton ... update="#form" />
And this updates only a specific component:
<h:messages id="messages" ... />
<p:commandButton ... update="messages" />
You can alternatively also use PrimeFaces own <p:messages> which supports auto-updating.
<p:messages ... autoUpdate="true" />
<p:commandButton ... />

Some, but not all UI Components are not responding.
Restart, rebuild code and clean caches.

<h:commandButton value="Sök"
action="#{infobean.getHouseSchedule}" update="resultTab">
</h:commandButton>
</p:panelGrid>
</h:form>
</ui:define>
Everything renders nicely but in this case only the button of the form is responding will says is fired. If I enlarge the page in the browser by changing the zoom the SelectOneMenu for the day is responding too, but never the the SelectOneMenu for the week. If I remove the panelGrid the form works as intended.
this is one example of the problem. On another page are tabs generatered by a script, in most cases 12-14. Often the last two or three are not responding/firing and there is no mouseover/hiver response. What really fiddles me is that is not always the case.

whenver i click the commandlinks present in the second or third tabs , after selection it navigates to the first tab , and its not staying in the tab where i performed the selection Say if i clicked the "click" link inside the juniper tab , then it navigates to the first tab. any suggestions are always welcome . thanks in advance
Use partialsubmit="true" in your commandlink.
The reason for the Accordian to reset itself is that once you click on any commandlink the whole form is being refreshed instead of the panel itself. Partial submit will do a partial refresh.

I have created a mobile web page using PrimeFaces Mobile. I am using PrimeFaces-4.0 and primefaces-mobile-0.9.4. Everything looks fine except that "update" property of p:commandButton does not work.

I have tried also 'update="#([id$=display])" ' as suggested here primefaces commandbutton update does not work but nothing changes. Can anyone help please?
I'm using the Dialog Framework in Primefaces 4.0 and I have the height set to the default (auto) which is fine until I click the Add button and it displays a validation message. Now the dialog height is too small and doesn't auto resize.
How can I make the dialog resize it's height on validation errors?

First of all, make sure that your dialog doesn't have fixed height, second make sure that overflow of the DOM element where the notification resides in the dialog has overflow properly set. Some dialogs are a bit tricky and do not re-size easily without closing and opening again, it would be easier to help you if you could show the actual dialog. My first tip would be to catch an event in front end with jQuery and resize the dialog accordingly.
I'm using JSF2 with Primefaces3.4.2 I have created a layout in layoutComplex.xhtml as below:

Yes,I can dynamically change the source of centerContentPanel without refreshing the whole page and just the centerContentPanel i.e for on click of menuitem present in the layoutComplex.xhtml,and then the colorPicker page's content will be displayed in the centerContenPanel. But issue is: I added a colorpicker.js in the layoutComplex.xhtml head and hope it can work when update centerContent, but actually, it's not working ..
but after refresh all page by press F5 ,it works fine as I expected. Why? How can i fix this?
Following is colorPicker.xhtml:
<ui:composition xmlns="http://www.w3.org/1999/xhtml"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:p="http://primefaces.org/ui">
<h:outputScript library="js" name="jscolor.js" target="head" />
<p:panel header="Colors">
<h:panelGrid columns="2" cellpadding="10">
<h:inputText class="color">
<p:ajax event="change" update="osssutcolor" />
</h:inputText>
<h:outputText style="display: none" id="osssutcolor" />
</h:panelGrid>
</p:panel>
</ui:composition>
and NavigationBean.java
package com.singtel.eshop.control;
import java.io.IOException;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.SessionScoped;
import javax.faces.context.FacesContext;
#SessionScoped
#ManagedBean
public class NavigationBean {
private String pageName = "blank";
public NavigationBean() {
}
public void doNav() {
String urlStr = FacesContext.getCurrentInstance().getExternalContext().getRequestParameterMap().get("urlParam");
this.pageName = urlStr;
}
public String getPageName() {
return pageName;
}
public void setPageName(String pageName) {
this.pageName = pageName;
}
}
You should call the jscolor.init after ajax call too. Seems like it is being called right after page load and needs to be called after your ajax call or inside your component. You can achieve this by calling jscolor.init in your colorPicker.xhtml file like this.
<ui:composition xmlns="http://www.w3.org/1999/xhtml"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:f="http://java.sun.com/jsf/core"

xmlns:p="http://primefaces.org/ui">
<h:outputScript library="js" name="jscolor.js" target="head" />
<script>
jscolor.init;
</script>
<p:panel header="Colors">
<h:panelGrid columns="2" cellpadding="10">
<h:inputText class="color">
<p:ajax event="change" update="osssutcolor" />
</h:inputText>
<h:outputText style="display: none" id="osssutcolor" />
</h:panelGrid>
</p:panel>
</ui:composition>
