collection.update inside Cursor.observe(changed) does not work

[mcwonka]

Hey folks,

we are facing an issue calling collection.update() inside a changed callback of Cursor.observer()

collection1 = new Mongo.Collection('collection1')
collection2 = new Mongo.Collection('collection2')

collection1.find().observe {

  added: (document) ->
    #is working
    console.log 'update 1', collection1.update({_id: newDocument._id}, {updateOnAdd: true}) 
    #is  working 
    console.log 'insert 1',  collection2.insert({insertOnAdd: true}) 


  changed: (newDocument, oldDocument) ->
    #is working
    console.log 'update 2', collection1.update({_id: newDocument._id}, {updateOnChange: true}) 
    # is _not_ working
    console.log 'insert 1',  collection2.insert({insertOnChange: true})  
}

Only the insert into collection2 on changed is not working although it returns 1 (affected rows). I think it has to do something with the simulation and that it is reset afterwards.It's strange to me that the insert works on added, but not on changed. Can you confirm this as a bug or is it intended that you can only update the observed collection on changed?

Thank you very much for your help!
Matthias
