JSF Form不向支持bean提交h：inputTextarea值

Question

以下是JSF弹出窗口的代码段。它在呈现表单时正确绑定controller.text值。但是，当我们单击OK时，没有在辅助bean上设置该值。

此外，我还可以在Chrome网络工具的帖子中看到提交的表单值。

<rich:popupPanel id="revisionTextBox" width="250" height="150">
       <f:facet name="header">Enter revision history text</f:facet>        
       <h:form method="post" action="#{controller.doSomething(this)}">
           <h:panelGrid>
              <h:inputTextarea
                id="text"
                binding="#{controller.text}"
                style="border-bottom-style: none; width:100%;overflow:hidden"
                disabled="false"
                immediate="true"
                cols="80"
                value="#{controller.textValue}"                 
                rows="7"
                >
                <f:ajax execute="@this @form"/>
                </h:inputTextarea>                      
              <h:panelGroup>
                 <h:commandButton type="button" value="OK" 
              onclick="#{rich:component('confirmation')}.hide();someFunction();return false" >                  
              </h:commandButton>
             <input type="button" value="Cancel"
              onclick="#{rich:component('confirmation')}.hide();return false" />
              </h:panelGroup>
           </h:panelGrid>
       </h:form>
    </rich:popupPanel>

控制器

@Controller
public class TreeController implements TreeToggleListener{

private UIComponent text;

private String textValue = "HI";


public String getTextValue() {
    return textValue;
}

public void setTextValue(String textValue) {
    this.textValue = textValue;
}

public UIComponent getText() {
    return text;
}

public void setText(UIComponent text) {
    this.text = text;
}

public void doAnotherSomething(){
    System.out.println("hi");
}
}
