betehess: found a bug in Play 2.0 https://play.lighthouseapp.com/projects/82401-play-20/tickets/269-wsexecutestream-always-returns-null

looks like they did not test this or that anybody is using these iteratees...

Hello!
14:37:37 [Deiu]
Does anyone in here work on rdflib.js?
14:38:13 [Deiu]
I have some questions. :)
14:43:21 [bblfish]
hi Deiu
14:43:45 [bblfish]
I am not the most knowledgeable on it but just ask your question...
14:45:11 [Deiu]
I'm trying to modify the foaf card example from rdflib.js repository, in order to add multiple URIs as input.
14:46:26 [Deiu]
If I try to display one webid at a time, it works just fine. However, if I pass a list (for which I then use a for loop) it breaks with "Uncaught TypeError: Cannot call method 'append' of undefined".
14:46:30 [bblfish]
ah yes I touched that code
14:46:52 [Deiu]
Example here: http://webid.fcns.eu/lookup/
14:47:14 [Deiu]
If you use only one URI, it works (no matter which).
14:47:50 [bblfish]
that's javascript, not java
14:48:12 [bblfish]
the best is to debug it with your browsers debugger
14:48:22 [bblfish]
Firefox, Chrome and Safari have good ones
14:48:35 [Deiu]
I tried, but no concrete results.
14:48:36 [bblfish]
you can set break points
14:49:05 [bblfish]
javascript like php is not statically typed
14:49:32 [bblfish]
so it looks to me like it is callind a method that does not exist or trying to append something on an non existent object
14:50:06 [bblfish]
I find javascript tricky because of that
14:50:27 [Deiu]
Yeah, but I'm not calling that method.
14:50:47 [Deiu]
Nor appending anything, anywhere...
14:51:17 [bblfish]
perhaps you did not transform your objects into URIs or perhaps it was not expecting a list
14:52:01 [Deiu]
If you use the example with one URI, it works.
14:52:04 [bblfish]
You can check my AddressBook code in there as another example
14:52:16 [Deiu]
It's the same code in the end, with a list containing a single element.
14:52:29 [danbri]
danbri has quit (Remote host closed the connection)
14:52:45 [bblfish]
perhaps it is rewriting the dom and deleted something which it has no pointer to on the second round
14:52:48 [Deiu]
The error appears once the loop has more than one iterations.
14:53:34 [Deiu]
Hold on...
14:56:58 [Deiu]
Nope, I'm only appending data, not overwriting.
14:59:00 [bblfish]
some of those debuggers may be able to point to the position the error is happening in the code
14:59:07 [bblfish]
I am myself not a js expert either
15:00:17 [Deiu]
I'll keep looking into it. Thanks though!
15:07:44 [bblfish]
you need to set a CORS proxy btw. IT should be set to data.fm already.

me reported that Scala Play 2.0 issue to the Play mailing list https://groups.google.com/d/topic/play-framework/xRlj37tiqjg/discussion
16:28:26 [bblfish]
damn it might have been faster writing this in java in the end...
17:18:54 [rszeno]
Deiu, it give me a error, 404 when i push display
17:20:06 [Deiu]
rszeno, try again
17:20:14 [Deiu]
It works over here..
17:27:25 [rszeno]
yes, here too

betehess: do you know how to convert (wrap) a java Future into an akka one?
19:37:34 [betehess]
no
19:37:51 [betehess]
can you register an callback to a java future?
19:38:04 [betehess]
if yes:
19:38:25 [betehess]
1. create akka Promise and return it as the akka future (it's a subtype)
19:38:52 [betehess]
2. on java future termination, send the result to the akka promise
19:38:59 [betehess]
should do it
19:39:24 [betehess]
you don't wrap, you chain the messages
19:39:54 [bblfish]
I got the future from netty using play
19:40:03 [bblfish]
play returns java Futures
19:40:24 [bblfish]
I think in fact I can register a callback
19:40:53 [bblfish]
because it is a netty ListenableFuture<T>
19:40:57 [bblfish]
ok
19:41:23 [bblfish]
got it
19:41:25 [bblfish]
thanks :-)
