我想要实现的目标是什么？
单击加载按钮后，如果设置了任何一个文本字段，那么结果“手风琴面板”过滤器应该展开。
点击加载按钮后，如果未设置所有文本字段，那么“手风琴面板”过滤器应该会崩溃。
我已经通过手风琴面板primefaces文档，但无法发现它有用。 http://www.primefaces.org/docs/vdl/3.5/primefaces-p/accordionPanel.html
我已经完成了之前在stackoverflow上提出的问题，这个问题的答案也无法让我满足我的要求。

我确实理解你要做的是什么，但是为了扩展/缩小手风琴面板，你可以使用这个
展开：PF('accordian-widgetVar').select(index)
崩溃：PF('accordian-widgetVar').unselect(index)
其中accordian-widgetVar是您的accordionPanel的属性widgetVar的值，index是您要展开/折叠的标签的索引
你也可以从像这样的bean执行它
RequestContext.getCurrentInstance().execute("PF('accordian-widgetVar').unselect(index)");
