Question

寻找一种在java中动态生成dropppable数据网格的方法。我能够在java中动态创建第一部分。这是我遇到麻烦的第二部分..

========第一部分=======

    <p:fieldset id="fieldset3" legend="Stuff2">
        <p:outputPanel id="dropArea3">
        <p:dataGrid id="datagrid3" var="ds" columns="6" rows="1"
            value="#{dataSourceController.fieldset3DataSources}" 
            paginator="true" 
            paginatorTemplate= "{CurrentPageReport} {FirstPageLink} 
                                {PreviousPageLink} {PageLinks} {NextPageLink}  
                                {LastPageLink}" 
            paginatorPosition="bottom"
            rowsPerPageTemplate="5,10,20">

            <p:column>
                <p:panel id="pnl" header="#{ds.title}" style="text-align:center">
                    <h:graphicImage library="images" name="datasource/#{ds.extension}.png"/>
                </p:panel>
                <p:draggable for="pnl" revert="true" stack=".ui-panel" cursor="move"/>
            </p:column>             
        </p:dataGrid>  
        </p:outputPanel>           
</p:fieldset>

========第二部分=============

<p:droppable id="droppable3" for="fieldset3" tolerance="touch"
                 activeStyleClass="ui-state-highlight" datasource="datagrid1">
        <p:ajax listener="#{dataSourceController.onDataSourceDropToFieldset3}"
                update="dropArea3 datagrid1"/>
</p:droppable>

此可放置部分在java：

中不起作用

        Droppable drp = new Droppable();
        drp.setId("droppable3");
        drp.setFor("fieldset3");
        drp.setTolerance("touch");
        drp.setActiveStyleClass("ui-state-highlight");
        drp.setDatasource("datagrid1");

        MethodExpression me = FacesUtil.createMethodExpression(
                "#{dataSourceController.onDataSourceDropToFieldset3}", 
                void.class, new Class[]{DragDropEvent.class});

        MyAjaxBehavior pajax = new MyAjaxBehavior();
        Class[] par = new Class[1];
        par[0] = BehaviorEvent.class;
        pajax.setListener( me );
        pajax.setProcess( "@this" );
        drp.setOnDrop("handleDrop");
        drp.addClientBehavior( "drop", pajax );  // NOT WORKING - java.lang.IllegalStateException: CDATA tags may not nest

        ucDsForm.getChildren().add(drp);

我收到此错误：

java.lang.IllegalStateException: CDATA tags may not nest

具体在执行时发生：

drp.addClientBehavior()

在此期间，我选择跳过动态可放置数据网格创建静态集合5。

动态地将droppable添加到primefaces datagrid
