在mgo中插入对象ID的数组

Question

So recently I've been trying to insert different types of data into structures using mgo, and I've ran into a bit of a snag. When trying to insert an array of object IDs, I can't seem to figure out that format if I were to populate that object ID array within the structure.

Here's the structure as follows

type Group struct {
ID        bson.ObjectId     `json:"id" bson:"_id"`
GroupName string            `json:"groupName"`
UserIDs   []*bson.ObjectId      `json:"users" bson:"userid"`
Expected  []*int            `json:"expected"`
Actual    []*int            `json:"actual"`
}

And the operation I am trying to run is to insert a new "test" table with a single userID into UserIDs.

array := []*bson.ObjectId{&findJ.ID}

c = Session.DB("test").C("Group")
err = c.Insert(&Group{GroupName: "test", UserIDs: array})
ThisPanic(err) 

Where findJ has it's own ID from a separate structure. What am I doing wrong here, as it is causing a panic on inserting the array.
