xwork相关知识点

使用xworks，但是数据不存在xwork的表，那么使用table,勾选的行数据的oid会是bean,需要做下面处理

在表单嵌入table，创建文档到table中完成页面创建之后不能刷新表，后台报ContextObject为空,手动刷新页面之后表中数据可以刷新出来

定义流程def文件需要在workflowTemplateDef.conf注册,不需要xconfmanager -p

xworks里的流程表单，也是可以不用创建Bean，直接用jca的table或者属性面板都可以的

xworks流程表单报workitem_details_attributes_group_input is null错误，是因为流程模板里任务的模板格式选择了原生，模板名称选择了通用模板，应该用ootb的jsp和default

xworks流程的附件处理类

AddFileAttachmentFormProcessorDelegate

xworks流程的附件显示builder

AttachmentGroupTableBuilder

xworks流程如果流程PBO是文档，那么附件列表只能获取当前文档版本对应的附件，如果PBO升版，就看不到之前版本的附件，在AttachmentGroupTableBuilder做如下修改

public Object buildComponentData(ComponentConfig config, ComponentParams params) throws Exception {
        LOGGER.debug("AttachmentGroupTableBuilder buildComponentData begin>>>>>>>>>>");
        WorkItem workitem = (WorkItem)params.getContextObject();
        //处理流程对象是文档的情况
        Persistable pbo = WorkflowUtils.getPrimaryBusinessObject(workitem); // 获得流程PBO
        if (pbo instanceof WTDocument) {
            LOGGER.debug("pbo is WTDocument>>>>>>>>>>");
            WTDocument doc = (WTDocument) pbo;
            return DocUtil.getSecondContent(doc);
        }
        String attachmentGroupId = (String)params.getParameter("groupId");
        return this.attachmentGroupService.getAttachments(workitem, attachmentGroupId);
    }

xworks下实现立即驳回功能，重写ootb的NmWorkItemCommandExecutor接口

            String key = NmCommandBean.convert(nextValue);
            if (key.indexOf("WfUserEvent") >= 0 && key.lastIndexOf("old") == -1) {
                return nmcommandbean.getTextParameter(nextValue);
            }
        } while (true);
        return "";
    }
