An atkShuttleRelation extends the atkManyToManyRelation. The relation shows two lists, one with elements that are currently linked to the master record, and one with available records to choose from. A many-to-many relation uses an intermediate table.

If you do not want to use the default primary keys, you can override them by using the functions:

setLocalKey("a_id");
setRemoteKey("b_id");


Example

One person (node A) can have several skills (node B) and the same skill applies to more than one person.


Be careful when using the AF_HIDE flag in the itermediate (A_B) node for the atkManyToOneRelation, in combination with multilanguage fields. When a relation is hidden, the key (a_id) will not be processed and no check on the language is done. This causes the added record to appear multiple times (once for every language), since a_id is not unique in the intermediate table.
