Multiple events fired on a subscription when insert element on a list

[Hanzofm]

Hi,

I have this structure RealTime structure

+Conversations
    -Conversation1
        -Messages
           -message1
           -message2

Initially I subscribe to the message changes with:

this.mylocalconversations.push({
     id,
     type,
     subscription: return 
      this.angularfire.object(Conversations/Conversation1/Messages);
       .snapshotChanges()
        .subscribe((conversation) => {
         console.log('new info')
       }),
   });

Then, i would insert new message with:

this.angularfire.list(Conversations/Conversation1/Messages).push(msg)

The result of this is:

new info
new info

Why the subcribe event fires twice?

Thanks

That would be your cache firing first and the server value next; I'm working on APIs to allow additional fidelity here. See #2012
