[GRASS-user] Index error: Unable to show attribute table of shapefile

Hi,

I'm receiving the following error on attempting to view shapefiles in GRASS
6.4.1 (on Ubuntu Lucid):

item = layer, log = self.goutput)
  File "/usr/lib/grass64/etc/wxpython/gui_modules/dbm.py",
line 653, in __init__

self.__createBrowsePage()
  File "/usr/lib/grass64/etc/wxpython/gui_modules/dbm.py",
line 698, in __createBrowsePage

self.mapDBInfo, layer)
  File "/usr/lib/grass64/etc/wxpython/gui_modules/dbm.py",
line 95, in __init__

keyColumn = self.LoadData(layer)
  File "/usr/lib/grass64/etc/wxpython/gui_modules/dbm.py",
line 247, in LoadData

self.AddDataRow(i, record, columns, keyId)
  File "/usr/lib/grass64/etc/wxpython/gui_modules/dbm.py",
line 286, in AddDataRow

if self.columns[columns[j]]['ctype'] != types.StringType:
IndexError
:
list index out of range

Any suggestions would be welcome.

Thanks,
Richard

Hi Richard,

What’s the command you’re entering, or are you using your own script?

Best,
Daniel

Hi Daniel,

I'm using the default menu items in GRASS.

I import the shapefile as follows:

Layer Manager > File > Import vector data > Common import formats > Select
ESRI shapefile > Browse and select file > Import

And then select the layer in 'Layer Manager', and click on the 'Show
attribute table' icon. Then the error results

'*Please wait loading attribute data..*' with the following in the command
console -

*if self.columns[columns[j]]['ctype'] != types.StringType:
IndexError
:
list index out of range
*

Perhaps related to upgrading from GRASS version 6.4.1.1 to 6.4.1.2. Maybe a
bug?

Thanks,
Richard

On closer inspection of the dbf file, some of the fields contain pipe (i.e.,
'|') characters. On removing these the attribute table can be displayed.

QGIS is able to display all data in the attribute, including 'pipe'
characters.

The question is, is this a bug in GRASS or should pipe characters not be
included in a shapefile dbf?

I encountered the same problem some time ago. For me this seems a bug in
GRASS. At first I though this to be a SQLite problem, but I can import and
view tables with pipe symbols in my SQLite manager. I ended up replacing the
pipe symbols.
