R – Sharepoint – trying to get value of a task field into a workflow

sharepointworkflow

I am making a sharepoint state machine workflow. The first state has a "create task with content type" as the task. The content type has a field called "isApproved". I am not using any infopath forms. I am trying to get the value o fthat field to evaluate if the document is approved or not. No matter what I do I am getting "object not set to an instance of an object".

I have tried all of the following:

createTaskWithContentType1_TaskProperties1.ExtendedProperties["isApproved"].ToString();
onTaskChanged1_AfterProperties1.ExtendedProperties["isApproved"].ToString(); 
onTaskChanged1.AfterProperties1.ExtendedProperties["isApproved"].ToString();

What am I doing wrong???

I had similar problems once, and I had to get the field ID to access the field. This is how I did it:

Guid isApprovedFieldId = worflowProperties.TaskList.Fields["isApproved"].Id;  
string approvalStatus = (string)(onTaskChanged1_AfterProperties1.ExtendedProperties[isApprovedFieldId]);

R – Creating a workflow task generates an “Invalid field name” error

Are you using the CreateTaskWithContentTypeId activity in your workflow? If you are then you need to ensure that the content types have been added to the Workflow Tasks list. SharePoint will not add them automatically.

Get username from SharePoint User field in List

Refer to this Article on how to get the User Details from the Field.

public static SPUser GetSPUser(SPListItem item, string key) {
     SPFieldUser field = item.Fields[key] as SPFieldUser;

     if( field != null) {   
         SPFieldUserValue fieldValue = field.GetFieldValue(item[key].ToString()) as SPFieldUserValue; 

         if(fieldValue != null)     
            return fieldValue.User; 
      }
      return null; 
 }

Your Code should be like this

SPUser spUser=GetSPUser(splistItem,"Owner");
String sUserName=(spUser!=null)?spUser.UserName:null;
