HI Guys,
I'm new in developing Liferay Portlets with JSF 2.0. Before that i developed JSF 2 Webapplication and now I'm trying to develop it as a Portlet, but i have some problems:
I want to pass parameters from one JSF page to another JSF page using <f:param> and <f:viewParam>. As pure JSF Webapplication its working great, but as Portlet, its not working anymore. I tried to find solutions in the net, but i hadnt success. To be simple, i created a simple small portlet, where i can type a text and this text should be shown in the next JSF page. Here is my code:
BackingBean:
@SuppressWarnings("serial")
@ManagedBean
@ViewScoped
public class BackingBean implements Serializable {
private String text;
public String getText() {
return text;
}
public void setText(String text) {
this.text = text;
}
public String navigate(){
Map<string, string> param = FacesContext.getCurrentInstance().getExternalContext().getRequestParameterMap();
this.text = param.get("text");
return "/views/view2.xhtml";
}
}</string,>
view.xhtml:
<!--?xml version="1.0"?-->
<f:view xmlns="http://www.w3.org/1999/xhtml" xmlns:c="http://java.sun.com/jsp/jstl/core" xmlns:f="http://java.sun.com/jsf/core" xmlns:h="http://java.sun.com/jsf/html" xmlns:ui="http://java.sun.com/jsf/facelets">
<h:head />
<h:body>
<h:outputtext value="Type something:" />
<h:form>
<h:inputtext value="#{backingBean.text}" />
<h:commandbutton action="#{backingBean.navigate()}" value="Send">
<f:param name="text" value="#{backingBean.text}"></f:param>
</h:commandbutton>
</h:form>
</h:body></f:view>
view2.xhtml:
<!--?xml version="1.0"?-->
<f:view xmlns="http://www.w3.org/1999/xhtml" xmlns:c="http://java.sun.com/jsp/jstl/core" xmlns:f="http://java.sun.com/jsf/core" xmlns:h="http://java.sun.com/jsf/html" xmlns:ui="http://java.sun.com/jsf/facelets">
<f:metadata>
<f:viewparam name="text" value="#{backingBean.text}"></f:viewparam>
</f:metadata>
<h:head />
<h:body>
<h:outputtext value="Given text: #{backingBean.text}" />
</h:body>
</f:view>
I would be glad about every help!
