Talking between 2 components

[Z. B.]

Talking between 2 components...

That is request something and do something with the response...

What are my options? 

option #1:

component1 -> trigger('askForAnId')

component2 -> on('askForAnId', getId)

component2 -> trigger('replyWithId')

component1 -> on('replywithId')

A bit ugly, but it doesn't work out of component3,4,5,etc. want to also 'askForAnId' unless i have all components listen on 'replywithId' and set a key on the payload to filter who it's actually for

option #2:

send a 'callback' function along with the payload to be run, seems the most reasonable

What do you guys do?

Are you triggering 'askForAnId' on document? All other components should listen for it on document too and it would work.

[Cristiano Oliveira]

Ui components trigger where this.$node is and Data components trigger on doc.body

I also have a mixin `uniqueId` which adds a guid and sets this._id to that.

When the response comes back, I'll do :

onGetFooResponse: function (resp) {

  if (resp._id == this._id) return;
