我在 PrimeFaces 论坛上问了这个问题，但没有得到回应，所以我想我会在这里尝试。
- 使用 PrimeFaces 3.0 -
我有一个包含 [p:layout] 和 [p:layoutUnit] 的页面，我想在支持 bean 中动态调整其大小。我有两种使用方法：
1) [p:commandButton] 调用一个支持 bean，它为 p:layoutUnit 组件中的 size 参数设置 bean 属性。我可以这样做，但为了使其工作，我必须设置 ajax="false" 和 update="@all" （可能不需要更新）以强制页面重绘。当我这样做时，将重置 的宽度，并且面板以所需的宽度绘制。
2）我有一个带有 p:ajax event="overlaySelect" 的 [g:map] 组件我想在激活 overlayEvent 时以类似的方式调整面板的大小。我遇到的问题是，如果没有完整的页面刷新，我似乎无法调整 [p:overlayUnit] 的大小，而且我似乎无法让 overlaySelect 事件导致页面刷新（或者它不这样做所以以一种会调整 [p:layoutUnit] 的方式。如果我刷新页面，它将调整大小。
我有两个问题：1）有没有办法动态调整 [p:layoutUnit] 组件的大小而无需进行完整的页面刷新？我似乎无法让它以任何其他方式工作。
2) 有没有办法强制 [p:ajax event="overlaySelect"] 强制完成页面刷新，以便我可以像在第一个场景中那样强制调整大小？
谢谢
如果有人感兴趣，这是页面代码：
