我正在尝试使用取消按钮关闭对话框，我收到事件但对话框没有关闭。经过大量挖掘后，我意识到问题在于对话框有一个带有票证描述的输入字段，但是当我删除它并且只留下de按钮时它可以工作。

这有什么意义吗？

表单基本代码

...
<p:commandButton icon="fa fa-bug" actionListener="#{ticketBean.viewTicket}"/>
...

TicketBean 代码

@ManagedBean
@ViewScoped
public class TicketBean {
...
public void viewTicket() {
    logger.info("--------------ViewTicket");
    Map<String, Object> options = new HashMap<>();
    options.put("modal", true);
    options.put("width", 640);
    options.put("height", 250);
    options.put("resizable", false);
    options.put("contentWidth", "100%");
    options.put("contentHeight", "100%");
    options.put("closable", false);

    RequestContext.getCurrentInstance().openDialog("maintenance/ticket", options, null);
}

public void cancel() {
    RequestContext.getCurrentInstance().closeDialog(null);
}
...

ticket.xhtml 对话框代码不起作用

解决办法是改代码

<p:inputTextarea rows="5" cols="70" value="#{ticketBean.ticket.descripcio}" >
</p:inputTextarea>

对于这个

<h:inputTextarea rows="5" cols="70" value="#{ticketBean.ticket.descripcio}" >
</h:inputTextarea>

问题似乎与 coponent p:inputTextarea

*可能的primefaces 6错误
