Single Job for Multiple Widgets

[William King]

I have a single job gathering data over websockets and pushing it immediately (using job.pushUpdate). I intended to have multiple widgets wired to this job. One would display text values, one would have a graph, etc.

But once I added the second widget, the first no longer received data (widget's onData never called). Am I doing something wrong or is this not supported?

The dashboard grid widgets contains:

{
  "row" : 1, "col" : 1,
  "width" : 1, "height" : 3,
  "widget" : "events",
  "job" : "events",
  "config": "events"
},
{
  "row" : 3, "col" : 2,
  "width" : 1, "height" : 1,
  "widget" : "events-chart",
  "job" : "events",
  "config": "events"
},

A couple of points:

• When I use setInterval and push fake data, both widgets display data.
• With real data, when I remove either widget, the other widget works fine.

In other words, both widgets work with real data so long as only one is on the board.

I figured out what I was doing wrong. I did not realize that a new job instance would be created for each reference to that job in the dashboard json. The way I organized my code meant that only one job.pushUpdate would ever get called. Sorry!

User error. Expected all references to a "job" to be the same instance of that job.

@williamking How did you fix this?
