How to handle Many-To-Many In Grails without belongsTo?
- by nute
I need to create a many-to-many relationship in Grails. 
I have a "Question" domain and a "Tag" domain. 
A Question can have 0 or more tags. A Tag can have 0 or more Questions. 
If I put a "hasMany" on each sides, it gives me an error saying I need a "belongTo" somewhere. 
However, adding a belongsTo means that the owner must exist... 
Like I said, a Tag could have 0 questions, and a Question could have 0 tags. 
There is no concept of an owner, it's a many-to-many! 
What am I supposed to do?
