Problem with scheduler and liveupdate


My liveupdate with node.js it’s working normally when i add or move an event in the scheduler but when i use

start_date: new Date(),
end_date: new Date(),
text: select_filleul,
filleuls_id_filleuls: select_id_filleul

i have this error:

Uncaught TypeError: Cannot call method ‘valueOf’ of undefined (dhtmlxscheduler.js:150)

excuse for my english language.


Please provide a full stack trace ( can be checked in js console ) or a demo link where issue can be checked, as from above message - it is not clear why the issue occurs.

Also, you are providing end_date similar to start_date which is invalid date range ( you can just skip end_date in case of addEventNow - it will use default event length to calculate it )


Nota: all is working before liveupdate and the problem is the same when i doubleclick
After error, it’s impossible to add or update an event i have to reload the page.

the trace:

return "<b>STATUT CLUB:</b> "+statut;

var dpsched = new dataProcessor("xml/scheduler.php");
dpsched.setTransactionMode("POST",true); // because i have connector


Sorry but it still not clear, what is the reason of the problem - the above code looks fine.


it seems to be a problem Date: ev.start_date and ev.end_date in scheduler.addEvent according dhtmlxscheduler.js: 3184 is undefined when the liveupdate is active:

the test:
if (ev.start_date.valueOf () == ev.end_date.valueOf ()) -> fails

nota: it’s ok when i move events not when i create


Updated live_update.js is attached , it must resolve the issue. (1.78 KB)

This seems still to be a problem,
I’ve installed the latest version and the same happens with me.
I can move the tasks but cant create new without getting that same error
