JSF 1.1数据表CRUD操作

Question

我们有一个使用JSF 1.1运行的旧应用程序，由于客户端规范而无法升级。

我想知道是否有可能与JSF 1.1有一个数据表，并在单击一个按钮或链接在数据表行打开一个对话框弹出并做CRUD操作?

感谢

我猜Apache Trinidad支持JSF 1.1。我可以在特立尼达做CRUD手术吗?

我认为将Richfaces 3.1.6(与JSF 1.1兼容)与A4J结合使用将有助于您实现这一目标:

<h:form id="myForm">
<rich:dataTable width="100%" style="border:none;margin-left:15px;" id="tableId" columnClasses="colClass"
            value="#{managedBean.someList}" var="someVar">
    <h:column> some content for this column </h:column>
    <h:column>
           <a4j:commandLink styleClass="linkClass" value="Delete" reRender="myForm:myModal" ajaxSingle="true" oncomplete="#{rich:component('myForm:myModal')}.show()" actionListener="#{managedBean.someMethodToUpdateDTO}">
              <a4j:actionparam value="#{someVar.idForExample}" name="someName"  assignTo="#{managedBean.someDTOObjectToBeUpdated.id}"/>
           </a4j:commandLink>
    </h:column>
</rich:dataTable>
<rich:modalPanel id="panel" width="350" height="100">
    <f:facet name="header">
    <h:panelGroup>
        <h:outputText value="Are you really, really sure to delete this one!!! #{managedBean.someDTOObjectToBeUpdated.name}"></h:outputText>
    </h:panelGroup>
    </f:facet>
    <a4j:commandButton styleClass="btnClass" value="Oui" ajaxSingle="true" oncomplete="#{rich:component('myForm:myModal')}.hide()" reRedner="myForm:tableId" action="#{managedBean.deleteIt}">
</rich:modalPanel>
</h:form>

someemethodtoupdatedto是一个方法，在您的托管bean中看起来像这样:

public void someMethodToUpdateDTO(ActionEvent event){
    //In this method I just load the object from somewhere else
    someDTOObjectToBeUpdated = someDAO.getObject(someDTOObjectToBeUpdated.getId()); 
    //someDTOObjectToBeUpdated is an attribute of your managed bean, of course with its     getter and setter
}

希望有帮助，
