java - Alfresco 社区 5.1.x 工作流表单动态添加输入字段

Question

我正在使用 Alfresco Community 5.1.x。我想在 + 按钮动态添加文本字段时使用 kickstart 创建一个自定义工作流，其中一种形式是我有 + 按钮。这可能吗？怎么办？

Answer 1

我希望你能从这个控件中得到一些想法。

在共享配置上，

        <field id="myco:userDetails" set="userDetails" label="User Details" >
            <control template="/org/alfresco/components/form/controls/workflow/userdetails.ftl" />
       </field>

用户详细信息.ftl

如果您希望此控件为只读，则在共享配置中添加 read-only="true"。

<field id="myco:userDetails" set="userDetails" read-only="true" label="User Details" >
            <control template="/org/alfresco/components/form/controls/workflow/userdetails.ftl" />
       </field>

请注意:截至目前，这还没有准备好生产，我们也处于开发模式。我们想改进此控件，请分享您的想法/意见/反馈。
