任何解决方案将受到高度赞赏.

推荐答案

如果您已经在使用JSF 2.x(您使用XHTML的声明(Facelets)证实了这一点或多或少)，则只需提交表单通过ajax.

If you're already using JSF 2.x (your statement that you're using XHTML (Facelets) confirms this less or more), just submit the form by ajax.

只需在表单的命令链接/按钮中添加以下标签即可:

It's a matter of adding the following tag to the command links/buttons of the form:

<f:ajax execute="@form" render="@form" />

这样，当前的<h:form>将由ajax提交，而当前的<h:form>仅将被呈现(更新/刷新).您可以根据需要通过添加其他客户端ID在render属性中指定其他要更新的组件.

This way the current <h:form> will be submitted by ajax and the current <h:form> only will be rendered (updated/refreshed). You can if necessary specify other to-be-updated components in the render attribute by adding other client ID(s).

如果您仍然使用旧的JSF 1.x，则可能需要查看RichFaces的Ajax4jsf子库，该子库基本支持相同的功能.

If you're still on the old JSF 1.x, you may want to look at Ajax4jsf sublibrary of RichFaces which supports basically the same.
