DatePicker calles onchange
--------------------------
Key: WICKET-1869
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.
