Datepicker: maxDate - last month - ctrl+arrow shortcut doesn't work properly

Hi,

there's a bug in jQuery.Datepicker. Shortcuts don't work properly, when you go to last avilable month.

Scenario:

1. Set in the datepicker code option: maxDate: "+12m" (as below in the code section)

2. Click on the input

3. press Page Up till you get to the last month (december 2012 in this case, since we've got 15.12.2011)

4. then try to press ctrl + left arrow - the selected date is going to be 14.11 (november) instead of 14.12 (december)

5. try to press Page Up again to get to 15.12.2012 - then press Page Down - the selected date should be 15.11.2012, but it's 2 months before (not 1) - 15.10.2012.

jQuery code:

$(document).ready(function() {

$("#datepicker").datepicker(

{

numberOfMonths: 2,

showButtonPanel: true,

minDate: 0,

showOn: 'both',

changeMonth: false,

maxDate: "+12m",

showOtherMonths: false,

selectOtherMonths: true,

hideIfNoPrevNext: true,

});

});

[...]

<input type="text" id="datepicker" />

Conclusion:

There are 2 issues,

1. ctrl + arrows: +-1 day selection in the last available date

2. page down +-1 month

Any ideas?

is it configuration issue or jQuery bug?
