      hello!

       

      i am facing a strange problem: in a form i would like to display parts of it by a certian condition (some param is set or not).

      if i put this in a panelGroup, the parts of the form seem not to be submitted. This only appears if i put them in a panelGroup, but not adding rendered directly to the input!

      anyone have an explanation?

       

      sample page 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:h="http://java.sun.com/jsf/html"
      xmlns:f="http://java.sun.com/jsf/core"
      xmlns:ui="http://java.sun.com/jsf/facelets"> 

<h:head>
    <f:metadata>
        <f:viewParam name="userid" value="#{testBean.userid}" converter="javax.faces.Long" />
        <f:viewParam name="action" value="#{testBean.action}" />
    </f:metadata>
</h:head> 
<body> 

    <h:form>
        id: <h:inputText value="#{testBean.userid}" /><h:outputText value=" set" rendered="#{not empty testBean.userid}"/><br/>
        action: <h:inputText value="#{testBean.action}" /><h:outputText value=" set" rendered="#{not empty testBean.action}"/><br/>
        <h:panelGroup rendered="#{not empty testBean.action}">
            editmode: <h:inputText value="#{testBean.mode}" />
            <h:outputText value=" set" rendered="#{not empty testBean.mode}"/>
            <br/>
        </h:panelGroup>
        <h:commandButton value="senden" action="#{testBean.submit}"/>
    </h:form>
</body> 
</html>

       

      sample bean code:

       

      import java.io.Serializable;

import javax.enterprise.context.RequestScoped;
import javax.inject.Named;

import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;


@RequestScoped
@Named
public class TestBean implements Serializable {

    private static final long serialVersionUID = -8792513244688669749L;
    private static final transient Log LOG = LogFactory.getLog(TestBean.class);

    private String action = "";
    public String getAction() {return action;}
    public void setAction(String action) {LOG.debug("set action="+action);this.action = action;}

    private long userid = 0;
    public long getUserid() {return userid;}
    public void setUserid(long userid) {LOG.debug("set userid="+userid);this.userid = userid;}

    private String mode = "";
    public String getMode() {return mode;}
    public void setMode(String mode) {LOG.debug("set mode="+mode);this.mode = mode;}

    public void submit() {
        LOG.debug("handle submit: action=" + action + ", mode=" + mode + ",userid=" + userid);
    }
}

       

      usage: type in an action, then the mode-input gets displayed. then type in a mode and sumbit. the mode will not get submitted correctly if the input is within the panelGroup!
