[xwiki-devs] Hide a field or Unique ID?

I am working on a Contacts application that will allow people to keep contact information on * Companies * Departments * People These can contain multiple: * Addresses * E-mail Addresses * Phone Numbers. First question: Is there already a ID field on each instance of an object? If not, I will want to generate one. If I do that, can I hide this ID field from the search engine? Second question: If I do a traditional many-to-many relationship where you would have a middle document that connects the many on both sides, (see document below) <http://xwiki.475771.n2.nabble.com/file/n7589555/many-to-many.png> Is it possible to query this type of relationship? -- View this message in context: http://xwiki.475771.n2.nabble.com/Hide-a-field-or-Unique-ID-tp7589555.html Sent from the XWiki- Dev mailing list archive at Nabble.com.
