我的search.xhtml页面在表单中有一些属性。 有一个搜索按钮，它通过辅助bean中的方法从db中获取列表。 列表，我在ui中使用：重复。 现在，当用户单击搜索按钮时，我希望列表和视图中的数据（xhtml）更新为ajax。
到目前为止，我已经尝试过了。我的search.xhtml页面

在SO上搜索了几个小时， 但只是无法弄清楚如何做到这一点。 使用JSF 2.0，Primefaces 3.3，Hibernate 3

您正在混合使用primefaces和核心JSF方法。尝试坚持使用primefaces开始并替换
<p:commandButton id="search" onclick="callme();" value="Search" actionListener="#{searchManagedBean.searchExactMatch2}" styleClass="p-search-btn" >
<f:ajax render=":searchResultsForm" />
</p:commandButton>
与
<p:commandButton id="search" onclick="callme();return true;" value="Search" actionListener="#{searchManagedBean.searchExactMatch2}" styleClass="p-search-btn" update=":searchResultsForm"/>
我已将on true添加到onclick，以确保不会忽略该事件并使用update属性而不是f:ajax标记。我不是百分之百确定素数update中的冒号，你也可以尝试没有它。

通过 c：forEach
替换 ui：repeat旧：
<ui:repeat id="userSearchResults" var="user" value="#{searchManagedBean.searchResults}">
..
</ui:repeat>
新：
<c:forEach id="userSearchResults" var="user" items="#{searchManagedBean.searchResults}" >
..
</c:forEach>
c：forEach 的命名空间定义：
