Hello,

I have seen this issue a whole bunch of times and it can have very many causes. The error usually looks something like: "SmartObject Method Update has required Property ID."

Cause #1:

• 
  
• Smartform/Workflow Designer Issue. 
  • 
    
  • Make sure that there is a Value being passed into the method that is failing. 
    
  • Make sure that this value is populated at the time the method is being called. 
    
  • If neither of these, move on to Cause #2. 
    
     
  
  
   

Cause #2:

• 
  
• SmartObject Design
  • 
    
  • If you don't think that the property giving us the issue should be required, check your SmartObject and see if the property is required there.
    
  • This can happen a lot with SharePoint solutions because for most of the methods, the Document/Attachment could be required for most methods, but for some it is not. If the property is required, you will get this issue.
    
  • If neither #1 or #2, move on to cause 3.
    
     
  
  
   

Cause #3:

• 
  
• Performance/Networking
  • 
    
  • This issue is usually seen when it comes to SharePoint as well. For example, the SharePoint call cannot be returned by the time Smartforms/Workflow needs the property.
