|
|
* In contrast to the original implementation, the URL-parameters "ParentClass" and "ParentID" are used
|
|
* to specify "Group" (hardcoded) and the GroupID-relation.
|
|
*
|
|
* @todo write a better description about what this field does.
|
|
*
|
|
* Returns either:
|
|
* - provided members
|
|
* - members of a provided group
|
|
* - all members
|
|
* - members based on a search-query
