Still, I wonder how come that Paul could successfully run my scripts... Anyway, big thanks to you. Martin

Rarely in my experience do things completely silently fail. If you run across such reproducible cases where an error completely disappears, file a bug report. Mason often gets line numbers right, but sometimes doesn't because of the way it's implemented. If you're not in a Mason special block (%args, %flags), most pure Perl errors (from % lines or %perl or %init) are fairly explanatory. The special blocks are, well, special and Not Quite Perl.
Re: [rt-users] Using Ajax with Mason in RT
Hi,
it appears I've reached a dead end...
This is my javascript ajax call (practically identical to the one Paul
posted):
jQuery.ajax
(
{
type: 'POST',
url: 'Elements/TestComponent',
data:
{
'ip': ip
},
dataType: 'json',
traditional: true,
success: successCallback,
error: errorCallback
}
);
According to Tamper Data, it gets sent and it looks like it contains the
right data.
This is my component:
% $r-content_type('application/json');
% JSON( \@something ) |n %
% $m-abort();
%init
my @something;
push (@something, 'something');
/%init
%flags
inherit = undef;
/%flags
The problem is, when I remove the flags section, the ajax call fails
with 403. If I keep it, I get back following error: syntax error at
/home/RT/RT-4.0.6/local/html/Ticket/Elements/TestComponent line 15, at EOF
Anyone got any idea?
Thanks,
Martin

Re: [rt-users] Using Ajax with Mason in RT
It may be a shot in the dark. But are you by chance editing the files in a windows text editor and copying them over? Or more specifically was it originally created on a windows box? There may be carriage returns in the file that are causing issues. If that is the case you can dos2unix the file and clean it up. I may be way off, but I have run into that in the past quite a bit with other *nix apps when users edit files in winworld. Sent from my mobile device.

I am editting the file via putty through ssh. As I don't use any special characters, I don't think this could be the reason. I have tried to move working script ./share/html/Helpers/Autocomplete/Groups to my local directory local/html/Ticket/Elements/ and the symptoms are the same. Not having inherit set to undef cause it to 403. Having it set results in the typical compilation error. I have also tried to move my component from local directory to share/html/Ticket/Elements, but that did not change anything. My question is - how can I diagnose, whether there is a problem with (auto|d)handlers? I haven't touched any of them since the installation. Martin

Ok, this is a real desperation measure, but I modified /opt/rt4/lib/RT.pm
and added a call to Carp::cluck in both the $SIG{__WARN__} and
$SIG{__DIE__} handlers. It adds a tiny bit more information in a few cases
that normally go unremarked by RT. Also, make sure and restart your server
after making changes, because the code that is supposed to pick up changes
doesn't always do so.

Thank you for not giving up...
My first attempt - putting cluck outside the block in handler that
checks for being inside eval. Looking inside the log and finding
bazillion of stack traces. Thinking about switching careers...
My second attempt - putting it in correct place. Looking inside the log
and finding nothing. Thinking about switching careers...
I always restart the apache server and reload the page before trying
something new. Working in debug mode, mason cache is empty.

Re: [rt-users] Using Ajax with Mason in RT
Just a quick update - Paul tried to run files from my machine on his and the result was that everything was working ok. So the situation is as follows: - brand new installation of RT-4.0.6 - database moved from RT-3.8.7, upgrade went well - only local changes are those mentioned in this thread, plus the RT_SiteConfig.pm and an import of one css file via css/base/main.css/End callback - $ uname -a Linux rt-mirror 2.6.32-5-686 #1 SMP Sun May 6 04:01:19 UTC 2012 i686 GNU/Linux Any ideas are welcome Thanks, Martin

403 is Forbidden. RT denies direct requests to /Elements/ directories
(among other internal components). This denial happens in RT's normal
request handling phase, which doesn't get called when you set inherit =
undef.
Please just remove the %flags section all together. You also lose

I'm betting it's the semicolon in the %flags section. Remove it. The
line number being off is Mason getting it wrong (I'll bet it's the line
# of the Mason object file).

Hi, I have used MakeClicky actions to extend the RT UI and now I would like my extensions to do some ajax stuff on click. I would like to know, how I can create new Mason component and set it as a valid target for the ajax request. Any help is really appreciated. Thanks, Martin

If you want your AJAX to return JSON, you need to do the following:
1. Do all the work of building the return component in the %init. I make
it a hashref called $ret.
2. In the web section of the file (the part that isn't enclosed in
%init or other Mason tags:
% $r-content_type('application/json');
% $m-clear_buffer;
% JSON::to_json( $ret, { utf8 = 1, allow_blessed = 1,
convert_blessed = 1, } ) |n %
% $m-abort;
3. Declare as %args all the parameters you pass it
4. Turn off any inheritance with
%flags
inherit = undef
/%flags
5. Call it in your Javascript like so:
jQuery.ajax({
type: 'POST',
url:'assign_ticket.mas',
data: {
'ticketid': ticketId,
'assignTo': rt_user_id,
'reason': reason,
'currentUserId':% $session{'CurrentUser'}-id %
},
dataType: 'json',
traditional:true,
success:changeStatusSuccessCallback,
error: changeStatusErrorCallback
});
function changeStatusSuccessCallback(json)
{
if (json.status == 'error')
{
alert('Error: ' + json.error_msg);
}
else
{
document.location.reload(true);
}
}
function changeStatusErrorCallback(jqXHR, textStatus, errorThrown)
{
alert(textStatus + : + errorThrown);
}
I'll leave it to you to figure out something better to do with the return
callbacks.
