Synchronous requests [solved]

MichMich

Take a look at how I did this with the newsfeed.

There is a Fetcher object that gets instantiated for every newsfeed. As soon as this feed receives new data it stores it in an instance variable and calls a function of the node_helper (see line 52 of the node helper).

That function then retrieves the the values of all the Fetchers’ instance variables and combines the data. It then sends the socket notification with the combined data.

I won’t pretend I completely understand what you did there :sweat_smile:
Is it okay if I copy that code, I managed to modify it in a way that seems to work :)

MichMich

@paviro Yeah, but try to understand what I did. Thats the best way to learn. Let me know what you don’t understand. I’ll explain.

paviro

I do not quite understand how the itemsReceivedCallbackworks :confused:

paviro

Does work great now! The only problem is sometimes a list is empty on a refresh even tough it should not be :/

{ inbox: [],
  'ViRO Entertainment': 
   [ 'Todo1',
     'Todo2',
     'Todo3' ]
 }

MichMich

I’m on my phone now, so not really able to explain the callbacks. Will do that later.

Regarding the empty lists: try debugging by putting some log statements on places where You receive and send data.

paviro

It is not the socket connection. The fetcher sometimes returns an empty list :/

MichMich

@paviro try debugging the Fetchet on the same way. ;)

paviro

I am on it but I can’t find the problem… :confounded:
When broadcastItems is fired and therefore fetcher.onReceive triggered the lists are populated. But once broadcastTodos() collects the tasks by looping over the fetchers some lists appear to be empty. Any chance you could have a look?

MichMich

Will fork your module tomorrow and give it a try.
