First of all, You need to use Future for this to return data from async call in method.
Second, Looks like you are trying to do code re-use with calling another meteor method.
IMO, you should not call the meteor method from another meteor method, which will create the another callback for getting results, which is added overhead and also make code unreadable. You should basically create the common function and try calling it from both Meteor method.
Following is listing, which should work
// define this future at top of file
Future = Npm.require("fibers/future")
Meteor.methods({
signupUser: function signupUser(rawData){
console.log("rawData :: "+rawData);
future = new Future()
Mesosphere.signupForm.validate(rawData, function(errors, exmp){
if(!errors){
console.log("No Errors Found");
var username = '';
var password = '';
console.log(rawData.length + ">>>>>>>");
for(var i = 0;i < rawData.length ; i++)
{
var obj = rawData[i];
if(i == 0)
{
username = rawData[i].value;
console.log(rawData[i].value + ">>>>>>>" + obj.value);
}
else(i == 1)
{
password = rawData[i].value;
}
}
//var obj = Meteor.call('ltest', username,password);
// replace above call to common method as described above
obj = common_ltest(username, password);
console.log("**********************"+obj);
future['return'](obj);
}else{
_(errors).each( function( value, key ) {
console.log("signupUser >> "+key+": "+value.message);
});
// assuming some error here, return null to client
future['return'](null);
}
});
// **note that, this important**
return future.wait()
}
});
Hope this helps
