Hi all,

Trying to intergrate the new calendar goodness into my BB10 application.

varStart = "20121129193000";

varDateStart = newDate(start.charAt(0) + start.charAt(1) + start.charAt(2) + start.charAt(3), start.charAt(4) + start.charAt(5), start.charAt(6) + start.charAt(7), start.charAt(8) + start.charAt(9), start.charAt(10) + start.charAt(11), 00);

The remote debugger then shows the date:

Sat 29 Dec 19:30:00

This is incorrect, the date I am expecting is Thursday 29th November 19:30:00.

Secondly, the operation where the date is added to the calendar returns error code 20 on the Dev Alpha.

Does anyone know where there is a list of error codes for BlackBerry 10 Development and WebWorks or what this one means - is it permissions based?

Okay, solved 1 problem. It was a permissions issue, was missing the <rimermissions> start and close tags.

Still be nice to know if there is a list of these cryptic error codes though. Also the date problem remains.

  <rimermissions>
    <rimermit>access_pimdomain_calendars</rimermit>
  </rimermissions>

The date problem occurs because the month index starts at 0, therefore 0 = January and 11 = December. For easier readability, you can try to format the "start" variable in order to use it when creating a date object instead of grabbing the characters one by one.

Oh okay, appologies for that - didn't realise that is specific for months. Seems a bit odd to me personally, given that days do obviously start with 1. I'm assuming there is some clever reason why the months are 0-11, but what an annoying pitfall to run into.

Thanks for your help!

No problem, glad to help. I'll just add some examples here:

var d = new Date("2012 11 29"); 

does not give the same output as

var d = new Date("2012", "11", "29");

If each parameter (y,m,d) is passed separately, they are interpreted as integer values (starting from index 0). You can test it out like this:

var a = new Date("2012 November 10");
a.getMonth();
// the output is: 10

var b = new Date("2012 December 10");
b.getMonth();
// the output is: 11
