Description Xavier Claessens 2014-04-26 14:21:38 UTC 
I've got a callback function with a GError** as last arg and it returns an object or NULL if error is set. When I implement that callback in JS code and I do:

  throw new Error("plop");

The the gjs console prints:

  (gjs:29398): Gjs-WARNING **: JS ERROR: Error: plop

And in the C code the the return value of the callback is NULL but the error is NULL as well.

Note that the gir looks correct to me:

<callback name="CMParamFilter" c:type="TpCMParamFilter" throws="1">

Yes, this is currently not implemented.

I had some wip patches at some point, but they weren't really working.
If you want to contribute, I can send you the old code...
Comment 2 Simon Feltman 2014-05-12 01:49:58 UTC 
This also needs work on the GI side of thing, see bug 729543.
Comment 3 Philip Chimento 2016-11-17 08:07:55 UTC 
Giovanni, I'd be interested in the old patches - would you like to post them here?
Comment 4 Giovanni Campagna 2016-11-22 23:54:26 UTC 
They are in bug 682701
