      <h:form id="form">
   <p:panel id="display">            
                <p:spacer width="20" />
                <h:panelGrid columns="6">
                    <h:outputLabel value="Address:"
                        style="text-align: left;display: block;width:130px;" />
                    <p:inputTextarea
                        value="#{companyInformationBean.current.officeAdd1}"
                        autoResize="true" style="width:170px;" maxlength="150" />

                </h:panelGrid>

                <h:panelGrid columns="6">
                    <h:selectBooleanCheckbox id="remember"
                        value="#{companyInformationBean.current.checkBox}">
                        <f:ajax event="click" execute="@form"
                            listener="#{companyInformationBean.checkBoxValue}" />
                    </h:selectBooleanCheckbox>
                    <h:outputLabel value="Same as Registered Office Address"
                        style="text-align: left;display: block;" />
                    <p:spacer width="20" />

                </h:panelGrid>
                <p:spacer width="20" />
                <h:panelGroup id="hidepanelgroup">
                <h:panelGrid id="getaddress" columns="6">
                    <h:outputLabel value="Head Office Address:"
                        style="text-align: left;display: block;width:130px;" />
                    <p:inputTextarea id="headadd"
                        value="#{companyInformationBean.current.headOfficeAdd1}"
                        autoResize="true" style="width:170px;" maxlength="150" />

               </h:panelGrid>
               </h:panelGroup>
   </p:panel> 
   </h:form>

Bean:

      public void checkBoxValue()
{
    if(current.getCheckBox()==true)
    {

            logger.info("getofadd"+current.getOfficeAdd1());
            current.setHeadOfficeAdd1(current.getOfficeAdd1());

    }
    else
    {
            logger.info("checkbox value false");
    }
}

推荐答案

您需要在< f:ajax render> 属性中指定要渲染的客户端ID.

You need to specify client IDs-to-render in the <f:ajax render> attribute.

因此，假设第二个文本区域的ID为 headadd ，则应该这样做:

Thus, given that the second textarea has an ID of headadd, this should do:

<f:ajax ... render="headadd" />

不相关与具体问题无关，将布尔值与布尔表达式中的布尔值进行比较确实没有任何意义.只需直接检查布尔值本身即可.

---

Unrelated to the concrete problem, comparing booleans against booleans in a boolean expression really doesn't make any sense. Just check the boolean itself directly.

if (current.getCheckBox())

顺便尝试使用自我记录的属性和方法名称.属性名称为 remember 会更合适.

By the way, try to use self-documenting property and method names. A property name of remember would be more suitable.
