是的,我认为这样做没有任何问题。如果需要,可以使用我的代码:
<rich:modalPanel id="popup" width="261" height="386" autosized="true"left="180" top="200" keepVisualState="true">
<h:panelGrid id="panelGrid">
<h:outputText value="#{PopupBean.output}" id="popupMessage"/>
<a4j:commandLink action="#">
<h:outputText value="Close" />
<rich:componentControl for="popup" operation="hide" event="onclick"/>
</a4j:commandLink>
</h:panelGrid>
</rich:modalPanel>
<h:panelGrid columns="2">
<a4j:commandLink action="#" reRender="panelGrid">
<h:outputText value="Yes" />
<rich:componentControl for="popup" operation="show" event="onclick"/>
<a4j:actionparam name="message" assignTo="#{PopupBean.output}" value="#{TestBean.input1}"/>
</a4j:commandLink>
<a4j:commandLink action="#" reRender="panelGrid">
<h:outputText value="No" />
<rich:componentControl for="popup" operation="show" event="onclick"/>
<a4j:actionparam name="message2" assignTo="#{PopupBean.output}" value="#{TestBean.input2}"/>
</a4j:commandLink>
</h:panelGrid>
基本上,模态面板中的输出将包含 TestBean 中的值
编辑(误解):
我相信您将不得不像这样定义您的模态面板:
<rich:modalPanel id="popup" width="261" height="386" autosized="true"left="180" top="200" keepVisualState="true"
binding="#{PopupBean.popupPanel}">
</rich:modalPanel>
在您的托管 bean 中,您将不得不使用 java 动态地将儿童添加到您的模式面板中,如下所示:
public String action_PoppingThePanel() {
HtmlCommandButton button = new HtmlCommandButton();
button.setValue("Yes");
String action = "#{TestBean.action_yes}";
MethodExpression methodExpression =
FacesContext.getCurrentInstance().getApplication().getExpressionFactory().
createMethodExpression(FacesContext.getCurrentInstance().getELContext(), action, null,
new Class<?>[0]);
button.setActionExpression(methodExpression);
getPopupPanel().getChildren().add(button);
button = new HtmlCommandButton();
button.setValue("No");
String action = "#{TestBean.action_no}";
methodExpression =
FacesContext.getCurrentInstance().getApplication().getExpressionFactory().
createMethodExpression(FacesContext.getCurrentInstance().getELContext(), action, null,
new Class<?>[0]);
button.setActionExpression(methodExpression);
getPopupPanel().getChildren().add(button);
getPopupPanel().setRendered(true);
getPopupPanel().setShowWhenRendered(true);
return null;
}
