Cannot read property 'rec_type' of undefined

Scheduler Javascript
#1

Hi guys

I keep getting this error “Uncaught TypeError: Cannot read property ‘rec_type’ of undefined”
when I delete an event.
I’m attaching some code, maybe you can spot the error:

scheduler

scheduler.config.lightbox.sections = [
{name: “lesson_id”, height: 21, map_to: “lesson_id”, type: “select”, options: scheduler.serverList(“lesson_id”)},
{name:“recurring”, height:115, type:“recurring”, map_to:“rec_type”, button:“recurring”},
{name: “time”, height: 72, type: “time”, map_to: “auto” }
];
render
$scheduler->render_table(“events”, “event_id”,“start_date,end_date,event_name,lesson_id,ev_user_id,rec_type,event_pid,event_length”);

My ‘rec_type’ field is a varchar(64)

Thanks

Hi,
try the latest version of js codebase, does the issue happens with it?
s3.amazonaws.com/uploads.hipcha … 140128.zip

Hi
It is the same.
If I try to delete the event I’ve just created I get the error “Cannot read property ‘rec_type’ of undefined”, but it works after I refresh the page.
Even then the event doesn’t disappear straight away. A line goes across the event title, but no error is displayed, and if I refresh the page once again it is gone.

Please double-check the server side response for delete operation - it must be an xml like next

<data> <action type="deleted" sid="123" tid="123"> </data>

Where sid must be the id of event that was deleted.

I couldn’t find the xml but this is the object event displayed on the console when it is created:

Object {start_date: Mon Feb 24 2014 08:55:00 GMT+0000 (GMT Standard Time), end_date: Mon Feb 24 2014 10:30:00 GMT+0000 (GMT Standard Time), text: “New lesson”, id: 1393321498861, _timed: true…}

Try to use Firebug or Chrome debug console. On network tab you can check all requests to server side and their responses.

I have moved to a different server and the same code was working on the old one.
Now I’m getting this error. Is this related to the permissions on the server?

<?xml version='1.0' ?>

Warning: error_log(log.txt): failed to open stream: Permission denied in /var/www/sites/dev.school360.co.uk/www/scheduler/codebase1/tools.php on line 205

Yep, on new server php has not write access to the connector’s folder and can’t write a log file. You can change folder access, or just comment enable_log command ( connector itself doesn’t need write access, it is necessary only for logging )

#9

Hi,

I have the exact same error but only in Chrome.
The PHP rply is a XML as you say:

<?xml version='1.0' ?>

I use Scheduler 4.0.
It works well on FF and IE. Only Chrome shows this error and we need to refresh calendar to make the event disappear.

#10

Are you using custom code or connector for server side operations ?
In first case - please check that content type of response is “text/xml”

#11

we use connector and answer is XML:

Connection:Keep-Alive
Content-Type:text/xml
Date:Tue, 18 Mar 2014 12:24:25 GMT
Keep-Alive:timeout=5, max=100
Server:Apache/2.2.22 (Win32) PHP/5.4.26 mod_ssl/2.2.22 OpenSSL/0.9.8t
Transfer-Encoding:chunked
X-Powered-By:PHP/5.4.26

RESPONSE:

<?xml version='1.0' ?>

Response looks correct :expressionless:
Is the demo page available online ? ( you can send me a PM with details )
