We migrated site collection successfully from MOSS 2007 to SharePoint 2010 using MetaLogix tool. Everything working fine but when we try to build OOB approval workflow, it is not giving the error but also not assigning the task to the assignee. We found that "start date" was missing in Task content type. We added using "Add from existing site column" After adding column, when try to reorder the column it is giving error and from correlation ID we found below error.
System.NullReferenceException: Object reference not set to an instance of an object. at Microsoft.SharePoint.ApplicationPages.ChangeFieldOrderPage.OnLoad(EventArgs e) at System.Web.UI.Control.LoadRecursive() at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)
The main problem is any kind of task assigning workflow is working even we tried using SP designer. In SPD when we try to add start approval process, start assign-to do item or any other task related action, Workflow is giving compiling error. I found ContentTypeID="" in .xoml config file of SPD workflow.
Any help really appreciate.
Thanks,
