There's something very strange going on.

I tried to view the data from table 'vias' and it worked. The difference from the other tables was the name of the geometry column (the_geom). I changed the name of the geometry column in table 'taxi' to 'the_geom', and now i'm getting this error message.

I'm sure I have data in the geometry column in the table 'taxi', so I don't have a clue of what might be happening.
The only thing that differs form the table 'vias' is that the geometries in 'taxi' are points and in 'vias' multilinestrings.
Do you know of other reason why I could be getting this error?

Thanks,
