Issue with JSF in GateIn

nandhana03 Nov 25, 2010 1:49 AM

I'm new to GateIn... I've successfully deployed a portlet in GateIn.... On editing the portlet, I'm unbale to retrieve the form values as a random string preceeds the form name. (something like _G7idhkasd897_jdhg67 followed by a colon , then the original form name). I'm using portletbridge-api-2.0.0.FINAL.jar & portletbridge-impl-2.0.0.FINAL.jar. My JSF version is JSF 1.2. The configuration I made :

faces-config.xml

---------------------------

<application>
<view-handler>org.jboss.portletbridge.application.PortletViewHandler</view-handler>
<state-manager>org.jboss.portletbridge.application.PortletStateManager</state-manager>

</application>

web.xml

------------

commented :

<context-param>
        <param-name>
            org.jboss.jbossfaces.WAR_BUNDLES_JSF_IMPL
        </param-name>
        <param-value>true</param-value>
    </context-param>

which I used earlier while deploying my application in JBoss portal.

Added :

<servlet-mapping>
<servlet-name>FacesServlet</servlet-name>
<url-pattern>/faces/*</url-pattern>
</servlet-mapping>

portlet.xml

----------------

<portlet>
         <description>Customer Portlet</description>
      <portlet-name>Customer Portlet</portlet-name>
      <display-name>Customer Portlet</display-name>
      <portlet-class>javax.portlet.faces.GenericFacesPortlet</portlet-class>
      <supports>
         <mime-type>text/html</mime-type>
         <portlet-mode>VIEW</portlet-mode>
      </supports>
      <portlet-info>
         <title>Customer</title>
         <short-title>Customer Portlet</short-title>
         <keywords>JSF, Portlet</keywords>
      </portlet-info>

      <init-param>
         <name>javax.portlet.faces.defaultViewId.view</name>
         <value>/views/customer/viewCustomer.jsp</value>
      </init-param>
       <init-param>
         <name>javax.portlet.faces.preserveActionParams</name>
         <value>true</value>
      </init-param>
      <init-param>
            <name>Administrator</name>
            <value>true</value>
      </init-param>
      <expiration-cache>-1</expiration-cache>
   </portlet>

Where are you trying to retrieve the form value from? Portal will generate some random id for all components not only for form. However if you specifiy a id, portal will honor that and it would something like random+your_id. The reason it's done that way because you could have same portlet multiple times on a page.

I'm using FacesContext.getCurrentInstance().getExternalContext().getRequestParameterMap() to retrieve the request parameters in my back-end bean. Suppose the form name is abc & I want to retrieve the value of a text box with id abc1. Earlier I used FacesContext.getCurrentInstance().getExternalContext().getRequestParameterMap().get('abc:abc1') to retrieve the value of the text box in my back-end bean. But now I cannot get the value by using the same code as that random string preceeds the form name. Is there any method to handle this ???

facesContext.externalContext.response.namespace

or

public String getNamespace() {
return externalContext.encodeNamespace("");
}

hii...... thnx 4 ur help...... I'm facing 1 more issue... from request map I'm getting _G6d3316b0_2d48bd_2d450f_2da091_2db08ec381dd58:j_id_jsp_436313122_0:abc:name

where 'abc' is the form id & 'name' is a text field whose value I need to retrieve.... By using the above method(the one which u told) in my back-end bean , I got G6d3316b0_2d48bd_2d450f_2da091_2db08ec381dd58. But I can find that in addition to this namespace something like j_id_jsp_436313122_0 also prepends the actual id. Will u plz help me to handle this also..... thnx in advace....

Seems that you have improper use of JSF components. Names of request parameters for JSF generated and processed by component itself, and you have no warranty what exact name is - it depends of JSF implementation, component version and environment. So, let JSF component to process these parameters and store them to beans. Creating fields by JSF component and processing them directly can cause unpredictable side effects.
You can only be sure about parameter name if you create it on yourself by JavaScript, using <f:param > tag or in similar way.

Unfortunately we can't do the work for you. There are plenty of examples out there (screencasts, documentation). Start here http://jboss.org/portletbridge
