i used tomahawk's panelTabbedpane component.
first, you have to import tomahawk-1.1.3.jar and commons-fileupload-1.1.1.jar to lib folder.
second, you have to add these lines to your web. xml file.
     
     <filter>
          <filter-name>MyFacesExtensionsFilter</filter-name>
          <filter-class>org.apache.myfaces.webapp.filter.ExtensionsFilter</filter-class>

Help needed for t:panelNavigation2 tag of Tomahawk

Hi,
I am using <t:panelNavigation2> panel component for myfaces. We are using http://www.irian.at/myfaces/panelnavigation_2.jsf example for our implementation.
Our requirement is to add image to the root component. If you look at the above example then we want to add image src before "Product Information" menu item and same for other menu items.
I am not sure whether <t:panelNavigation2> is providing any img attribute.
Let me know if there are any ways to do so.
Regards
Chintan

Using Tomahawk t:tabChangeListener/ with t:panelTab/

Hi ,
I am using tomahawk <t:panelTabbedPane/> tag. However I would like an action event to be fired and would like to refresh my page on clicking a particular tab(i.e.<t:panelTab />) on the pane.On searching google I found <t:tabChangeListener/>.But i dont now how to use it.If anyone has idea of how to use it or any other alternative solution , it would be of great help.This is an emergency.

I'd guess these questions need to be anserwed by AT&T...

T:tabChangeListener tag not recognized error when using in facelets

I am trying to use tomahawk's TabChangeListener with PanelTabbedPane, but when I add the tabChangeListener tag in the body of the <t:panelTabbedPane /> , I get an error: "<t:tabChangeListener> Tag Library supports namespace: http://myfaces.apache.org/tomahawk, but no tag was defined for name: tabChangeListener". I have used many other tomahawk components with no problem. Do I have to configure my tomahawk taglib to include that tag? I am using tomahawk in facelets.

Help with the custom tag

Hi
i want to make a custom tag encapsulating certain functionalities of existing tags in one tag namely tomahawk dataPanel and html facets.
Where can I get the source for html jsf tags so that I can look into it and modify.

If you have in your jsps a reference to the tld like this:
<%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html" %>
make a C:\WEB-INF\ directory on your PC and copy in there your tlds
(C:\WEB-INF\struts-html.tld). The same for linux: /WEB-INF/struts-html.tld.
So you do not have to change anything in web.xml nor in the jsp pages!
Bye,
Marco.

Dynamically building 'value' attributes with EL

I'm trying to create an <af:inputText> component with a dynamic 'value' attribute. I'd like to generate something like this:
<af:inputText value="#{myBean.myField}"/>
Where 'myField' is a string stored in another var...#{myField}.
Essentially I'd like to concatenate '#{myBean.', #{myField}, and '}' and use it to dynamically specify the value that the inputText is mapped to.
Is there a way to do this with the JSF EL?
Thank you.

I'm almost positively sure that you cannot do what you want to do.
But why do you want do do such a thing like that?
If you want to do a reusable page, you can use the alias bean tag of Tomahawk (www.myfaces.org)

<t:panelTabbedPane serverSideTabSwitch="false">
     <t:panelTab id="tab1" label="TabbedPanel1">
         <f:verbatim><jsp:include page="profile.jsp"/> </f:verbatim>
</t:panelTab>it is working fine. but when i try to include a jsf page , which has taglib directives to include core and html components of jsf, it is giving error on server console as well on browser also...
stack trace ...

Thanks in advance...

Hi...Thanks for reply...

public class MyBean {
    public HtmlPanelTabbedPane getTabbedPane() {
      HtmlPanelTabbedPane tabbed = new HtmlPanelTabbedPane();
      //Loop as desired
      HtmlPanelTab tab = new HtmlPanelTab();
      tab.setLabel("My tab");
      tab.setId("tab_0");
      tabbed.getChildren().add(tab);
      return tabbed;
}However, once I have my dynamically added tabs, I run into trouble when I want to populate them. Is there a convenient way to add JSF content to these tabs, defined using regular JSF tags? If not I guess I'll have to generate all the content using Java. I'm having a hard time finding much information about how to set values (EL expressions for example) and bindings for the components inside the tabs. Any ideas are appreciated!

Once you are in the programmatic realm, I am not aware of a standard way to include components generated from a view representation like a JSP or Facelet file.
As to the EL expressions, use UIComponent.setValueExpression() along with Application.getExpressionFactory() and ExpressionFactory.createValueExpression(). For the action attribute of the command components, use UICommand.setActionExpression() and ExpressionFactory.createMethodExpression().

Please post the relevant parts of the web.xml (all the URL mappings and filter configurations) and what is the URL you are using to access the resource which generates the error.

Would tomahawk selectOneRadio work in html table tag

hey guys,
i want to use the tomahawk tag in a html table in JSF pages, but it seen unwork, my example is shown below
<f:view>
<h:form>
<table>

<x:selectOneRadio id="select" layout="spread" forceId="true" forceIdIndex="false" value="#{LIC3320.currentSelect}">
<f:selectItem itemValue="dog" itemLabel="Dog"/>
<f:selectItem itemValue="cat" itemLabel="Cat"/>
<f:selectItem itemValue="fish" itemLabel="Fish"/>
</x:selectOneRadio>
<f:verbatim>
<tr><td align="center" colspan="4">
</f:verbatim>
<x:radio for="select" index="0"></x:radio>
<f:verbatim>
</td></tr>
</f:verbatim>

</table>
</h:form>
<f:view>
the main problem is the radio isn't in the table, it came before the table and show at the top of the table. Is if i use tomahawk tag, i must use datetable in JSF?
Thanks
emmy

We have successfully used the Tomahawk radio component within a plain table using JSF 1.1 (MyFaces 1.1.5) and JSF 1.2 (the Sun RI 1.2_04). We also use facelets however and so did not use the verbatim tag.
Did you try looking at the component tree to see if it is in the correct order?
What implementation and version of JSF are you using?
Which version of Tomahawk?
Did you check the generated HTML to see if it is what you expect?

T:selectOneRadio requiredMessage tag is not foune in tomahawk lib

Hello,
I want to give custom required message for radio button when user do not select one. But i didn't get any tag like JSF has "requiredMessage".
Can anyone suggest me how to implement this functionality.
code for select one radio is follow:
              <t:selectOneRadio id="sor" value="SI" layout="pageDirection"
               required="true" >
               <f:selectItem id="si1" itemLabel="" itemValue="sa"/>
               <f:selectItem id="si2" itemLabel="" itemValue="lo" />
               <f:selectItem id="si3" itemLabel="" itemValue="lg" />
               <f:selectItem id="si4" itemLabel="" itemValue="bq" />
          </t:selectOneRadio>What i need is to give requiredMessage like in JSF, we can give as follows:
              <h:selectOneRadio id="sor" value="SI" requiredMessage="Please Select Radio" id="radio" required="true">
               <f:selectItem id="si1" itemLabel="" itemValue="sa"/>
               <f:selectItem id="si2" itemLabel="" itemValue="lo" />
               <f:selectItem id="si3" itemLabel="" itemValue="lg" />
               <f:selectItem id="si4" itemLabel="" itemValue="bq" />
          </h:selectOneRadio>But i didn't find any tag like requiredMessage in tomawak.
Can anyone help me on this?
Thank you,
Bipin Sutariya

The Tomahawk components are (Java) extensions of the standard components, so since the property is on the standard component, it will be on the Tomahawk component. If you are using Facelets, then no problem, just use the property and it ought to work. If you are using JSP, you need to hope that the tag implementation includes the property.

Tomahawk panelTabbedPane and panelTab index

Hi.
I use Tomahawk components in my web pages.
In my panelTabbedPane, I use a loop to load the component of each panelTab.
<t:panelTabbedPane serverSideTabSwitch="true">
<c:forEach items="${actionTool.tabsList}" var="tab">
<t:panelTab label="#{tab.label}">
<ui:include src="#{tab.link}" />
</t:panelTab>
</c:forEach>
</t:panelTabbedPane>
I would like to load only the select panelTab. What can I do ?
Can I get the instance of PanelTabbedPane created ?
Can I get the actual panelTab activated via the panelTabbedPane ?
Tanks.

Ah well .. I misunderstood "imbricated form errors".
Sorry, I don't have practical experience with this specific component. But such a construction just works with IBM's odc:tabbedPanel.
You might try to look for another components. I know, IceFaces also have a tabbedpanel component.

Problem in tomahawk panelTabbedPane

Hi
I m trying to use the panel tabbed pane with the serversidetabswitch = true. Therefore I have declared a tab change listener with the following source code
public class TabSupport implements Serializable, TabChangeListener
private static final long serialVersionUID = 1L;
int selectedTabIndex;
public TabSupport()
public int getSelectedTabIndex() {
//System.out.println(" Property getSelectedTabIndex() accessed " + selectedTabIndex);
return selectedTabIndex;
public void setSelectedTabIndex(int selectedTabIndex) {
//System.out.println(" Property setSelectedTabIndex() accessed");
this.selectedTabIndex = selectedTabIndex;
public void processTabChange(TabChangeEvent event){
System.out.println("TabSupport:processTabChange() called " + event.getNewTabIndex() + " " + event.getPhaseId());
this.selectedTabIndex = event.getNewTabIndex();
}When I change the tab the listener is invoked which sets selectedTabIndex value accordingly and I can see this through the system message. But in the generated html the selected tab content doesnt show meaning selectedTabIndex is still 0. It hasnt been assigned to the new value or has been overwritten. TabSupport is in the session scope. Following is my jsp code

Hassnain

even though the issue is a little bit old, but with this extension the solution of hassnaimbadami works fine:
if you call the function "processTabChange" the servlet creates a new insatnce of the class TabSupport. if you get the right instance of the backing bean which actually refers to the "#{tabSupport.selectedTabIndex}" from the context every thing works.
For exampel like that:
public void processTabChange(TabChangeEvent event){
backingBean = (TabSupport) FacesUtils.getManagedBean("tabSupport")
backingBean.setTabindex(event.getNewTabIndex());
---> FacesUtils:
package ..
import javax.faces.application.Application;
import javax.faces.application.ApplicationFactory;
import javax.faces.FactoryFinder;
import javax.faces.el.ValueBinding;
public class FacesUtils {
     * Get managed bean based on the bean name.
     * @param beanName the bean name
     * @return the managed bean associated with the bean name
     public static Object getManagedBean(String beanName) {
          Object o = getValueBinding(getJsfEl(beanName)).getValue(FacesContext.getCurrentInstance());
          return o;
     private static ValueBinding getValueBinding(String el) {
          return getApplication().createValueBinding(el);
     private static String getJsfEl(String value) {
          return "#{" + value + "}";
     private static Application getApplication() {
          ApplicationFactory appFactory = (ApplicationFactory)FactoryFinder.getFactory(FactoryFinder.APPLICATION_FACTORY);
          return appFactory.getApplication();
}

Are there any restrict to layouts of the tomahawk tag: inputFileUpload

As mentioned in title, I use this tag in two jsps. The first is directly included in a h:form, And the second is in a
ui:composition component of, like below:
<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:c="http://java.sun.com/jstl/core"
xmlns:fn="http://java.sun.com/jsp/jstl/functions"
xmlns:t="http://myfaces.apache.org/tomahawk">
But the first page can work without any problem, while the second page can't get the upload value, always return null
I'll be so appreciate if anyone would give some tips.

The uploaded file will be null if either the extensions filter isn't configured properly or you aren't using the multipart/form-data encoding type for the POST request.
