DatePickerCtrl crashes on windows - Invalid date in wxDateTime::Set()

Hi,

I’m trying to use a DatePickerCtrl, but I cannot create one unless I use the style DP_ALLOWNONE.

The only way I can use one is if I set DP_ALLOWNONE, and then use SetRange. Otherwise it crashes the app with:

wx._core.PyAssertionError: C++ assertion “(0 < day) && (day <= GetNumberOfDays(month, year))” failed at …\src\common\datetime.cpp(1221) in wxDateTime::Set(): Invalid date in wxDateTime::Set()

import wx

app = wx.App()
frame = wx.Frame(parent=None, title=‘Test’)

Crashes

wx.DatePickerCtrl(frame, wx.ID_ANY, wx.DefaultDateTime, wx.DefaultPosition,
wx.Size( 105, -1 ), wx.DP_DROPDOWN)

Crashes

wx.DatePickerCtrl(frame, wx.ID_ANY, wx.DateTimeFromDMY(1, wx.DateTime.Jan, 2010),
wx.DefaultPosition, wx.Size( 105, -1 ),
wx.DP_DROPDOWN|wx.DP_ALLOWNONE)

OK

dp = wx.DatePickerCtrl(frame, wx.ID_ANY, wx.DefaultDateTime, wx.DefaultPosition,
wx.Size( 105, -1 ), wx.DP_DROPDOWN|wx.DP_ALLOWNONE)

But then setting any value crashes

dp.SetValue(wx.DateTimeFromDMY(1, wx.DateTime.Jan, 2010))

However, if we set range first

dp.SetRange(wx.DateTimeFromDMY(1, wx.DateTime.Jan, 2000), wx.DefaultDateTime)

Then it’s OK

dp.SetValue(wx.DateTimeFromDMY(1, wx.DateTime.Jan, 2010))

frame.Show(True)
app.MainLoop()

Everything worked fine in wxPython 2.8. I tried 3.0.2 and 3.0.3 and get the same results. It works fine on Linux.

Also,I’m using Python 2.7.

Does anyone have any idea on how I can work around this?

Thanks
