[Qgis-developer] Wrong $length

[Paolo Cavallini]

Hi all.
The calculation of $length on the attached file returns weird results:
when calculated as virtual field is ok, whereas when updating an
existing field a negative result is given. I assume this is related to
topological errors in the line, but nevertheless the diff between the
two methods is unexpected.
Furthermore, "Update all" does not seem to work on a column where
sorting is applied (by clicking on column head).
Anyone confirms? Should I open two tickets?
Thanks.
