如果我在我的数据表中删除我的 p:commandButton 上的“渲染”属性，我只能让我的 actionListener 触发。不确定是什么问题。
页面代码：
<ui:define name="content">
<H1>Manage Delegates</H1>
<P>In order to raise requests on behalf of other users in the system, and to be able to access, attach and update
personal information such as travel details and credit card details, you must be authorised to act on the users
behalf.</P>
<P>Please use the button below to as a user for their permission to act on their behalf within the Admin Direct
system.</P>

<h:messages id="generalMessages"></h:messages>

<H1>Your Delegate Requests (The users you can act on behalf of in Admin Direct)</H1>
<P>The following list represents the users you have requested to be a delegate form, and the status of those requests. You will be able to create tasks and edit the personal details of these users if your request has been Approved, and if they have authorised you to (1) create tasks for them in the system, and (2) edit their personal details.</P>
<P>If you wish to act on behalf of someone else within Admin Direct, please request delegate access using the "Request Delegate" button below. You can monitor the status of the request from here, but will also receive email confirmation once a response (Approve/Reject) has been received within the system.</P>
<P>Once a request has been approved, you will be able to select that user when creating tasks to indicate that the task is being created for someone else, but you will be able to specify that you are the primary contact during the tasks processing.</P>

有问题的项目在这里：
<p:column headerText="Resend Email" style="width:100px">
<p:commandButton
id="resendRequest"
rendered="#{delegateBean.requestIsPending(sentRequest) or delegateBean.requestIsRejected(sentRequest)}"

process="@this"
update="@all"
actionListener="#{delegateBean.resendRequest(sentRequest)}" />
</p:column>

这是永远不会被调用的代码，除非我删除渲染的属性：
public void resendRequest(DelegateRequest request) {
AdminDirectUser requester = this.getUser(); // fresh database pull
System.out.println("Resending request");
RequestContext context = RequestContext.getCurrentInstance();
if (requester == null) {
context.addCallbackParam("error", true); // basic parameter
dialogMessage = "An issue occured locating your account details.";
setErrorMessage(dialogMessage);
return;
}
String server = FacesContext.getCurrentInstance().getExternalContext().getRequestServerName();
int port = FacesContext.getCurrentInstance().getExternalContext().getRequestServerPort();
String app = FacesContext.getCurrentInstance().getExternalContext().getRequestContextPath();
AdminDirectUser adUser = request.getAdminDirectUser();
if (adUser == null) {
context.addCallbackParam("error", true); // basic parameter
dialogMessage = "An issue occured, unable to locate the person within Admin Direct.";
setErrorMessage(dialogMessage);
return;
}
request.setDelegateRequestStatus(this.getPendingStatus());
request.persist();
String url = "http://" + server + ":" + port + app + "/pages/customer/delegateResponseForm.jsf?requestId="
+ request.getId();
System.out.println("url " + url);
sendMailBean.sendDelegateRequest(request);
setMessage("Request for delegate access has been re-sent to " + adUser.getFullName());
}
任何建议表示赞赏。
