GetDefaultEditorForType(): Unknown data type name []

[Petr Hlávka]

Hello,

after migration from wxPython 2.6.3.2 to 2.8.4.0 (and Python 2.3 to
2.5) I encounter strange errors when operating with grid in my app. I
have own GridBaseTable and some registered custom grid types (for bool
values). Sometimes (usually only for random cells) I've got an
exception:

attr = wx.grid.GridCellAttr()
File "C:\Python25\Lib\site-packages\wx-2.8-msw-unicode\wx\grid.py", line 513,
in __init__
_grid.GridCellAttr_swiginit(self,_grid.new_GridCellAttr(*args, **kwargs))
wx._core.PyAssertionError: C++ assertion "wxAssertFailure" failed at ..\..\src\g
eneric\grid.cpp(10223) in wxGrid::GetDefaultEditorForType(): Unknown data type n
ame []

The GetTypeName method always returns non-empty value so this error is
quite strange for me. I'm not able to send the whole code here and
when I try to cut off some snips, everything works correctly...

Have anyone similar problems or could someone point me to the root of
the problem.

  Thanks, Petr Hlavka.
