Meteor: Meteor.call() from within observe callback does not execute

Question

Is there any possibility of calling a server method from within a observe callback in Meteor?

I put together an example that reproduces the issue, that

This might be a known issue, i'm not sure since I've not tried it myself, but it looks like there might be a workaround (see https://github.com/meteor/meteor/issues/907)

Add your Meteor.call into an instantaneous setTimeout callback:

added: function(doc) {
    console.log("added "+doc.text);
    setTimeout(function() {
        Meteor.call('aMethod',doc.text,function(e,r){
            if(e){
                console.log("error from server: "+e);
            }else{
                console.log("response from server: "+r);
            }
        });
    },0);
}

Btw Tarang's answer also works when calling from a client method. Essentially I have a file in the client scope. And this file is a method definition. Inside my method definition I call a method at the server.

I was having problems because only the client stub of the server call is being called and the server method does not get called. The fix was this one:

Meteor.methods({  
    assignUserSession: function(options) {
        setTimeout(function() { // https://stackoverflow.com/questions/18645334/meteor-meteor-call-from-within-observe-callback-does-not-execute
            // Find all the base_accounts of this user and from there decide which view to prioritize.
            Meteor.call('user_base_accounts', {user_id: Meteor.userId()}, function(error,result){
                ....
                //server is then called due to logs shown in the command prompt
                ....
            });
        });
    }
});

Thanks for pointing this out!
