[OSM-talk] Osmosis - error when trying to apply a change file

[simon at mungewell.org]

Hi all,
I'm trying to get Osmosis to apply a change file to a data set, although I
think I am following the instructions on the wiki it throws an error...
"Task 3-apply-change does not support data provided by default pipe"

Example is below, where I have 'upgraded' a village to a city (don't worry
this is just a test).

Any suggestions?
Simon.
