Igor Vaynberg resolved WICKET-1869.
-----------------------------------

    Resolution: Won't Fix
      Assignee: Igor Vaynberg

all that magic you dont like happens inside yui code. we have to call widget.select() as far as i understand, so there is no way around this.

there is another calendar in wicket-stuff which might work better for you.

>                 URL: https://issues.apache.org/jira/browse/WICKET-1869
>             Project: Wicket
>          Issue Type: Bug
>          Components: wicket-datetime
>    Affects Versions: 1.4-M3
>            Reporter: Łukasz Wysocki

> Prerequisites:
> TextField with a date alredy set (say an initial value) and an DatePicker added.
> Action:
> Press the Calendar icon.
> Effect:
> The TextFields onchange event is fired.  It should not be fired becouse the value was alredy set and not given by the calendar.
> Where to start:
> file: wicket-date.js 
> function Wicket.DateTime.showCalendar (line 146) does an widget.select(date) -> in there we have this.selectEvent.fire(validDates); (line 3470) -> in there ret = s.fn.call(scope, this.type, args, s.obj); (line 254) -> AND :) in there we ALWAYS execute the onchange if (field.onchange != null && typeof(field.onchange) != 'undefined') field.onchange(); (line 186). 
> Why is it a important for me -- i have an AJAX callback on the TextField which updates the text field after onchange (makes it red if  one of validation rules failes). Effect for my is that when i click the calendar it shows and then is hidden again becouse the field is aded to ajax target and rendered again with the calendar hidden.
