1. Create a computer class and linux class and their serial number lookup entity

2. Create relationship mapping between computer and linux

3. Computer class reference field has reference to linux server class

4. Run final preview, encountered InvalidWildCardRuleException

[Siyou Li · Accepted solution]

User needs to create all mappings for main class first, then at last step create lookup mapping.

For example, user wants to create a mapping between computer and linux server class. And both computer and linux server class has its serial number lookup class. The steps should be below:

1. Create computer and linux server classes

2. Add attribute mapping to computer and linux server classes, however, do not map any lookup class such as serial number lookup in attribute mapping

3. Finish all reference mapping and relationship mapping between computer and linux server classes first, for example, computer's reference field can reference linux server class, and computer class has relationship mapping with linux server class

4. After all parent level mapping is finished including relationship mapping step, now go back to attribute mapping step, and create serial number lookup for computer and linux server class in their corresponding attribute mapping section
