7000 XmlField JonathanStatusTypes not found error in K2 Service Manager

Hello,

I am currently doing a code in K2 wherein it involves the following requirements:

1. 
   
2. All of Jonathan orders should fall into our page 1.
   
3. All of Ray orders should fall into our page 2.
   
4. All of Domingo orders with Trade equal to XXX and YYY should fall into page 1.
   
5. All of Domingo orders with Trad NOT equal to XXX and YYY should fall into page 2.
   

I have an available data xml for this and I found nothing wrong in my code.

I am receiving the error of "7000 XmlField JonathanStatusTypes not found" in K2 Service Manager.

Please help me out in resolving this issue.

Thanks in advance.
