尝试使用 jsf2.0 (Mojarra) 开发复合组件,该组件应根据 bean 的列表动态呈现命令按钮。我能够渲染按钮,但没有触发操作。有人可以帮我解决这个问题吗?
下面是代码
<composite:interface>
<composite:attribute name="buttonList" required="true"
type="java.util.List" />
<composite:attribute name="beanName" required="true"
type="java.lang.Object" />
</composite:interface>
<composite:implementation>
<ui:repeat var="listItem" value="#{cc.attrs.buttonList}">
<h:commandButton value="#{listItem.buttonName}"
action="#{cc.attrs.beanName.listItem.buttonAction}">
</h:commandButton>
</ui:repeat>
</composite:implementation>
这用作
<utils:buttonGroup buttonList="#{testButtonBean.buttonList}"
beanName="#{testButtonBean}" />
豆子看起来像
public class TestButtonBean {
public List<ButtonPOJO> buttonList = new ArrayList<ButtonPOJO>();
public List<ButtonPOJO> getButtonList() {
return buttonList;
}
public void setButtonList(List<ButtonPOJO> buttonList) {
this.buttonList = buttonList;
}
public void preProcess() {
if (null != buttonList && buttonList.size() == 0) {
ButtonPOJO ob1 = new ButtonPOJO("Continue", "next");
ButtonPOJO ob2 = new ButtonPOJO("Back", "prev");
buttonList.add(ob1);
buttonList.add(ob2);
}
}
public String next() {
return "page1";
}
public String prev() {
return "page2";
}
}
