SharePoint 2013 Workflow 状态栏失效

在新的SharePoint版本中，并不直接支持状态栏，需要做如下配置才能生效

1. 添加引用C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\15\TEMPLATE\WorkflowActivities\Microsoft.SharePoint.WorkflowServices.Activities.dll

2. 如果需要支持直接绑定，在关联文件中，添加属性

<Property Name="MetaInfo" 

Value="WSEventContextKeys:SW|StatusColumnCreated;#WorkflowService\r\nCreatedBySPD;

#WorkflowService\r\nCurrentWebUri;#WorkflowService\r\nHistoryListId;

#WorkflowService\r\nSharePointWorkflowContext.ActivationProperties.SiteId;

#WorkflowService\r\nTaskListId;#WorkflowService\r\nSharePointWorkflowContext.ActivationProperties.WebId;

#WorkflowService\r\nMicrosoft.SharePoint.ActivationProperties.ListId;

#WorkflowService\r\nMicrosoft.SharePoint.ActivationProperties.ListName;

#WorkflowService\r\nMicrosoft.SharePoint.ActivationProperties.CurrentItemUrl;

#Instance\r\nMicrosoft.SharePoint.ActivationProperties.ItemId;

#Instance\r\nMicrosoft.SharePoint.ActivationProperties.ItemGuid;

#Instance\r\nStatusFieldName;#WorkflowService\r\nMicrosoft.SharePoint.ActivationProperties.RelatedItems;

#Instance\r\n
StatusColumnCreated:SW|1
StatusFieldName:SW|OData__x7533__x8bf7__x8bf7__x5047_
" />

3. 在工具栏中增加控件

4. 再在流程定义图里引用这个控件就可以了。
