ui:include in richfaces 4 仅在第二次单击时更新
我是 Richfaces4 和 JSF2 的新手,遇到很多问题。相同的代码突然开始工作,然后就崩溃了。目前,我有一个 ui:include 标签,当单击 a4j:commandLink 时,它会更新页面。使用 Eclipse 的调试功能,我可以看到正在调用方法,并且正确的值存储在 bean 中,但页面永远不会更新,直到我第二次单击它。看起来页面是在支持 bean 中设置值之前更新的。以下是我的代码。在我更新到 MyFaces 2.1.3 之前,MyFaces 2.0.2 中也存在同样的情况。
<a4j:outputPanel id="pagePanel" layout="block">
<ui:include src="#{panelMenu.currentPage}"></ui:include>
</a4j:outputPanel>
<h:panelGrid>
<p><a4j:commandLink value="View Member" render="pagePanel" execute="pagePanel">
<a4j:param value="/pages/group_member.xhtml" assignTo="#{panelMenu.currentPage}"/>
</a4j:commandLink></p>
<p><a4j:commandLink value="View/Edit Groups" render="pagePanel" execute="pagePanel">
<a4j:param value="/pages/group_detail.xhtml" assignTo="#{panelMenu.currentPage}"/>
</a4j:commandLink></p>
</h:panelGrid>
I am new to Richfaces4 and JSF2 and having lots of issues. Same code start to work suddenly and then it breaks. Currently I have a ui:include tag that update the page when the a4j:commandLink is clicked. Using debugging feature of eclipse I can see that the methods are being called and correct value is stored in the bean but page never gets updated until I click on it the second time. It seems the page is updated before the values are set in the backing bean. Following is my code. The same thing was working in MyFaces 2.0.2 before I updated to MyFaces 2.1.3.
<a4j:outputPanel id="pagePanel" layout="block">
<ui:include src="#{panelMenu.currentPage}"></ui:include>
</a4j:outputPanel>
<h:panelGrid>
<p><a4j:commandLink value="View Member" render="pagePanel" execute="pagePanel">
<a4j:param value="/pages/group_member.xhtml" assignTo="#{panelMenu.currentPage}"/>
</a4j:commandLink></p>
<p><a4j:commandLink value="View/Edit Groups" render="pagePanel" execute="pagePanel">
<a4j:param value="/pages/group_detail.xhtml" assignTo="#{panelMenu.currentPage}"/>
</a4j:commandLink></p>
</h:panelGrid>
