对于 PT-146833(7.5.1632.8/20200430) 之前的版本，第三方系统用单点登录的方法打开信息中心-待处理任务列表会报如下错误：

可以在待处理任务[WF_AssignmentBill]的列表插件中增加如下python插件，可避免该错误。

import clr

clr.AddReference("System")

clr.AddReference("System.Core")

clr.AddReference("Kingdee.BOS")

clr.AddReference("Kingdee.BOS.Core")

from Kingdee.BOS import *

from Kingdee.BOS.JSON import *

from Kingdee.BOS.Core import *

from System import *

from System.Collections.Generic import *

from System.Linq import *

def OnInitialize(e):   

    if this.View.OpenParameter.GetCustomParameter("Status") == None :

        this.View.OpenParameter.SetCustomParameter("Status", "UnCompleted");

        this.View.ParentFormView = None;

如果是已处理任务列表[WF_AssignmentHisBill]，则增加以下Python脚本

import clr

clr.AddReference("System")

clr.AddReference("System.Core")

clr.AddReference("Kingdee.BOS")

clr.AddReference("Kingdee.BOS.Core")

from Kingdee.BOS import *

from Kingdee.BOS.JSON import *

from Kingdee.BOS.Core import *

from System import *

from System.Collections.Generic import *

from System.Linq import *

def OnInitialize(e):   

    if this.View.OpenParameter.GetCustomParameter("Status") == None :

        this.View.OpenParameter.SetCustomParameter("Status", "Completed");

        this.View.ParentFormView = None;
