Indicator not showing up in StyledTxtCtrl with Lexer

In the following code, the indicator isn’t shown unless I comment out the SetLexer line.
Is this a bug? Is there a work-around?

import wx, wx.stc

if ‘main’ == name:

app = wx.App()

frame = wx.Frame(None)
panel = wx.Panel(frame)

editor = wx.stc.StyledTextCtrl(panel)

editor.SetLexer(wx.stc.STC_LEX_PYTHON)

editor.SetText("testing testing testing")

editor.IndicatorSetStyle(0, wx.stc.STC_INDIC_PLAIN)
editor.IndicatorSetForeground(0, wx.RED)

editor.StartStyling(1, wx.stc.STC_INDICS_MASK)
editor.SetStyling(10, wx.stc.STC_INDIC0_MASK)


sizer = wx.BoxSizer(wx.HORIZONTAL)
sizer.Add(editor, proportion=1, flag = wx.EXPAND)
panel.SetSizer(sizer)

frame.Show()   
app.MainLoop()

Forgot to mention:
wxPython 2.8.8.1 (gtk2-unicode)
Ubuntu 8.04

# only accepts old style indicators,
    # Python Lexer only allows Indicator-2

cheers,

Thanks, it works! Here’s the fixed snippet for the record:

import wx, wx.stc

if ‘main’ == name:
app = wx.App()

frame = wx.Frame(None)
panel = wx.Panel(frame)


editor = wx.stc.StyledTextCtrl(panel)

editor.SetLexer(wx.stc.STC_LEX_PYTHON)

editor.SetText("testing testing testing")

editor.IndicatorSetStyle(2, wx.stc.STC_INDIC_PLAIN)


editor.IndicatorSetForeground(0, wx.RED)

editor.StartStyling(1, wx.stc.STC_INDICS_MASK)
editor.SetStyling(10, wx.stc.STC_INDIC2_MASK)

sizer = wx.BoxSizer(wx.HORIZONTAL)
sizer.Add(editor, proportion=1, flag = wx.EXPAND)

panel.SetSizer(sizer)
frame.Show()

app.MainLoop()

oops, the line
editor.IndicatorSetForeground(0, wx.RED)
should be
editor.IndicatorSetForeground(2, wx.RED)
