Primefaces dataTable with embedded commandLink
提问by c12
I'm trying to embed a Primefaces commandLink and call an action listener from a link inside a column of a Primefaces dataTable. Is this not possible? The "Test" onclick alert gets fired but it never makes it to my bean's method.
我正在尝试嵌入 Primefaces commandLink 并从 Primefaces 数据表的列内的链接调用动作侦听器。这不可能吗？“测试”onclick 警报被触发，但它永远不会进入我的 bean 的方法。
<p:dataTable var="location" value="#{adminBean.locations}">
<p:column headerText="Options">
<p:commandLink value="delete" actionListener="#{admin.deleteLocation}" onclick="alert('test')"/>
</p:column>
</p:dataTable>
bean code:
豆码：
public void deleteLocation(ActionEvent e){
//delete logic here...
}

This is possible. Your actionListener should be called. Keep in mind that the p:commandButtonuses ajax by default. So you should use the updateattribute in order to define the components to be updated.
这个有可能。你的 actionListener 应该被调用。请记住，p:commandButton默认情况下使用 ajax。因此，您应该使用该update属性来定义要更新的组件。
However, I don't know if this affects the actionListener. Did you try it with actioninstead of actionListener?
但是，我不知道这是否会影响 actionListener。你试过用action而不是actionListener吗？
Here is an example how I got it working:
这是我如何让它工作的一个例子：
<p:commandLink action="#{spc.selectPatient(item)}"
ajax="false"
value="Open"/>
The bean method looks as follows:
bean 方法如下所示：
public String selectPatient(Patient p) {
// do something
// return some outcome
}
