Without any user action: You can replace the button with a outputText component, move the code in doSomthing() into the constructor and thats it!

Here is a working example with a thread instead of a scheduled task:

Code:

 @ManagedBean(name = "prendererTestView")
 @SessionScoped
 public class PortableRendererTestView implements Serializable {
 
 	public final String GROUPNAME = "mygroup";
 
 	private String buttonText = "click me";
 
 	public PortableRendererTestView() {
 		PushRenderer.addCurrentSession(GROUPNAME);
 	}
 
 	public void doSomething(ActionEvent event) {
 		buttonText = "In progress";
 		new Thread(new MyRunnable(this)).start();
 	}
 
 	public String getButtonText() {
 		return buttonText;
 	}
 
 	public void setButtonText(String buttonText) {
 		this.buttonText = buttonText;
 	}
 
 	public class MyRunnable implements Runnable {
 
 		private PortableRendererTestView view;
 		private PortableRenderer renderer;
 
 		public MyRunnable(PortableRendererTestView view) {
 			this.view = view;
 			renderer = PushRenderer.getPortableRenderer();
 		}
 
 		@Override
 		public void run() {
 			try {
 				Thread.sleep(30000);
 			} catch (InterruptedException e) {
 				e.printStackTrace();
 			}
 			this.view.setButtonText("click me again");
 			renderer.render(GROUPNAME);
 		}
 	}
 }

Code:

 <ice:commandButton value="#{prendererTestView.buttonText}" actionListener="#{prendererTestView.doSomething}"/>

If you click on the Button the button text changed from "click me" to "in progress" and a thread starts. After 30 seconds the button-text changed to "click me again".

Hello,

i never tried it but i think you can activate a scheduler on first request. And in the scheduled task you use the push api. Look at "Pushing from outside the JSF context" in the docs:

http://wiki.icefaces.org/display/ICE/Ajax+Push+-+APIs

Hello,

i get the following warning:

WARN: No response sent to request '/myapp/faces/javax.faces.resource/listen.icepush' with ICEfaces ID 'null' from 127.0.0.1 in 600 minutes. Unblocking thread 'btpool0-7'.

The ICEfaces ID is null!
The ThreadBlockingAdaptingServlet gets the ICEfaces Id with:
Code:

  request.getParameter("ice.session")

Do I have to set the ice.session request parameter for myself?

For example on user login:
Code:

 request.setParameter("ice.session", username + sessionid);

Best regards,
Jonas

Another solution-> Use a JSF2.0 UIComponent instead of facelets:

http://blogs.sun.com/enterprisetechtips/entry/true_abstraction_composite_ui_components

Now i can handle optional attributes with default values...here is one example component:
Code:

 <html 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:ice="http://www.icesoft.com/icefaces/component"
       xmlns:composite="http://java.sun.com/jsf/composite">
 
 <head><title>(For validation only)</title></head>
 <body>
 
 <composite:interface
         displayName="Input Text"
         shortDescription="Input Text component." >
     <composite:attribute name="id" required="true"
             displayName="Id"
             shortDescription="Id of the intput-text component"/>
     <composite:attribute name="label" required="true"
             displayName="Label"
             shortDescription="Label"/>
     <composite:attribute name="required" default="false"
             displayName="required"
             shortDescription="Required"/>
     <composite:attribute name="value"
             displayName="value"
             shortDescription="value"/>           
 </composite:interface>
 
 <composite:implementation>
 	<div style="position: relative;width: 100px; float:left; margin-top:5px; text-align: right;">	
 		<ice:outputLabel value="#{cc.attrs.label}:" for="#{cc.attrs.id}" styleClass="custIceOutLbl"/>
 	</div>	
 	<div style="position: relative;">	
 		<ice:inputText id="#{cc.attrs.id}_inputText" label="#{cc.attrs.label}"  required="#{cc.attrs.required}" value="#{cc.attrs.value}"/>
 		<ice:message id="error_#{cc.attrs.id}" for="#{cc.attrs.id}_inputText" showSummary="true" showDetail="true" effect="#{globalEffectBean.newEffect}" tooltip="true"/>
 	</div>
 </composite:implementation>
 </body>
 </html>

With Firebug i can see that the app tries to get

http://localhost:9090/myapp/faces/javax.faces.resource/listen.icepush

and gets a http 404 Not found error.

I noticed something else...(not related to the topic)
Icefaces loads a javascript file from:

http://yui.yahooapis.com/combo?3.1.1/build/oop/oop-min.js&3.1.1/build/event-custom/event-custom-min.js&3.1.1/build/attribute/attribute-base-min.js&3.1.1/build/base/base-base-min.js&3.1.1/build/event/event-base-min.js&3.1.1/build/dom/dom-min.js&3.1.1/build/node/node-min.js&3.1.1/build/event/event-delegate-min.js

Why is it done and what is if the app server has no access to the yahooapi.com adress?

a simular problem:

http://www.icefaces.org/JForum/posts/list/17876.page

but i won't change my servlet mapping from "/faces/*" to "*.jsf".

Hello,

i updated from Beta1 to Beta2 and get the following warning:

WARNING: JSF1091: No mime type could be found for file listen.icepush. To resolve this, add a mime-type mapping to the applications web.xml.

in german:
com.sun.faces.context.ExternalContextImpl getMimeType
WARNUNG: JSF1091: Für Datei listen.icepush konnte kein Mime-Typ gefunden werden. Fügen Sie eine Mime-Typ-Zuordnung zur web.xml der Anwendung hinzu, um dies aufzulösen.

I suspect that the server push not working correct, because the progress bar of the outputProgress Component is not working for me.

How can I fix it.

Best Regards,
Jonas

Ok i have found the solution here:

http://www.ibm.com/developerworks/java/library/j-facelets/

There is a example "Passing Actions":

In custom component -> action="#{backingBean[action]}"
Code:

 <h:commandLink id="#{action}" value="#{label}"  
                               action="#{backingBean[action]}"/>

Using:
Code:

 <cust:columnCommand label="Edit" action="editCD" 
 backingBean="${CDManagerBean}"/>

It works with validators too ;-)

Best Regards,
Jonas

EDIT: Still one problem: How to handle optional attributes?

errormessage: //C:/.../META-INF/components/inputSecret-component.xhtml @7,206 validator="#{backingBean[validator]}": Target Unreachable, identifier 'backingBean' resolved to null

Hello,

I want to create a custom component. But I don't know how i can set default values for attributes with flag required = false. And I can not refer validators from view.

Here is my example component (inputSecret-component.xhtml):
Code:

 <div 	xmlns:ice="http://www.icesoft.com/icefaces/component"
   		xmlns:f="http://java.sun.com/jsf/core">
 		<ice:outputLabel value="#{label}:" for="#{id}" styleClass="custIceOutLbl"/>
 		<ice:inputSecret id="#{id}" label="#{label}" required="#{required}" value="#{value}" immediate="#{immediate}" partialSubmit="#{partialSubmit}" validator="#{validator}" binding="#{binding}"/>
 		<ice:message id="error_#{id}" for="#{id}"/>
 </div>

First example:
Code:

 <cust:inputSecret id="password" label="new Password" value="#{myView.newPassword}" immediate="true" partialSubmit="true" validator="#{myView.validateNewPassword}" />

It appears the faces message:
//C:/...META-INF/components/inputSecret-component.xhtml @4,193 validator="#{validator}":
/detail.xhtml @26,189 validator="#{myView.validateNewPassword}":
The class 'de...MyView$$EnhancerByCGLIB$$123c457' does not have the property 'validateNewPassword'.

Second Example without validator:
Code:

 <cust:inputSecret id="password" label="new Password" value="#{myView.newPassword}" immediate="true" partialSubmit="true" />

It appears the faces message:
//C:/...META-INF/components/inputSecret-component.xhtml @4,193 validator="#{validator}":
Identity 'validator' was null and was unable to invoke

Is there a simple solution for this?

In Firefox: On mouseover the style of the submenus changed from

Code:

 left: 241px; top: 1px; display: none;

to
Code:

 left: 241px; top: 1px;

This doesn't happen in IE8 or Chrome.

The DIV for the Menu has no onmouseover attribute. There must be a javascript snippet that fires the mouseover event for the div over the id...or so..

Here is a example div (from Chrome):
Code:

 <div xmlns="http://www.w3.org/1999/xhtml" class="iceMnuBarItem"
 	id="navigationMenuForm:j_idt13:j_idt14:_6"
 	onmouseout="Ice.Menu.hideOnMouseOut('navigationMenuForm:j_idt13',event);"><a
 	class="iceCmdLnk" href="javascript:;"
 	id="navigationMenuForm:j_idt13:j_idt14:_6:link" onblur="setFocus('');"
 	onclick="var form=formOf(this);form['navigationMenuForm:j_idcl'].value='navigationMenuForm:j_idt13:j_idt14:_6:link';return iceSubmit(form,this,event);"
 	onfocus="setFocus(this.id);"><span class="iceOutTxt iceMnuItmLabel"
 	id="navigationMenuForm:j_idt13:j_idt14:_6:out">Administration</span></a></div>
 <div xmlns="http://www.w3.org/1999/xhtml" class="iceMnuBarSubMenu"
 	id="navigationMenuForm:j_idt13:j_idt14:_6_sub" style="display: none">

Where can I find the javascript snippet which adds the onmouseover event to the iceMnuBarItem div?

Best Regards,
Jonas

Hello,

i have the same problem in IE8. In Firefox the menu works.
