我有以下<h:panelGrid>
:
<h:panelGrid columns="2" id="panelGrid" >
<!-- heading -->
<f:facet name="header">
User Details
</f:facet>
<h:outputLabel value="#{bundle.ViewUserdetailsLabel_id}"/>
<!-- adding in a small effect here that will fade a message when a user hovers over the id number or username -->
<h:outputLink id="id1" value="#">
<h:outputText id="id" value="#{userdetailsController.selected.id}" title="#{bundle.ViewUserdetailsTitle_id}"/>
</h:outputLink>
<p:tooltip for="id" value="This is your I.D. Number" showEffect="fade" hideEffect="fade" />
<h:outputText value="#{bundle.ViewUserdetailsLabel_username}"/>
<h:outputLink id="username1" value="#">
<h:outputText id="username" value="#{userdetailsController.selected.username}" title="#{bundle.ViewUserdetailsTitle_username}"/>
</h:outputLink>
<p:tooltip for="username" value="Your registered username, this can be changed" showEffect="fade" hideEffect="fade" />
<f:facet name="footer"></f:facet>
</h:panelGrid>
我希望它显示为
User Details Id: 500 Username: zzzzzzzz
然而,它显示了一些空单元格:
User Details Id: 500 Username: zzzzzzzz
使用<p:panelGrid>
代替<h:panelGrid>
时,问题仍然存在。这是怎么造成的,我该如何解决呢?
答案 0 :(得分:8)
在面板网格中,每个直接子组件都计为单个表格单元格。
这些<!-- heading -->
和<!-- adding ... -->
条评论行将每个评为一个孩子。因此,这些也将每个计为单个表格单元格。
要解决此问题,只需通过以下web.xml
条目告诉Facelets在视图构建期间跳过所有注释:
<context-param>
<param-name>javax.faces.FACELETS_SKIP_COMMENTS</param-name>
<param-value>true</param-value>
</context-param>
然后有<p:tooltip>
,它也算作单个表格单元格,即使它不代表任何直接内容。您需要将工具提示及其目标组件包装在<h:panelGroup>
中,以便它表示单个表格单元格(此外,您也可以将注释放在那里)。
<h:outputLabel value="#{bundle.ViewUserdetailsLabel_id}"/>
<h:panelGroup>
<!-- adding in a small effect here that will fade a message when a user hovers over the id number or username -->
<h:outputLink id="id1" value="#">
<h:outputText id="id" value="#{userdetailsController.selected.id}" title="#{bundle.ViewUserdetailsTitle_id}"/>
</h:outputLink>
<p:tooltip for="id" value="This is your I.D. Number" showEffect="fade" hideEffect="fade" />
</h:panelGroup>
<h:outputText value="#{bundle.ViewUserdetailsLabel_username}"/>
<h:panelGroup>
<h:outputLink id="username1" value="#">
<h:outputText id="username" value="#{userdetailsController.selected.username}" title="#{bundle.ViewUserdetailsTitle_username}"/>
</h:outputLink>
<p:tooltip for="username" value="Your registered username, this can be changed" showEffect="fade" hideEffect="fade" />
</h:panelGroup>
