according to the Pixel & Tonic site Assets is capable of doing an replacement of existing files based on filename. It should allow to upload a new version with the same name (providing me with a choice of replacement) and without breaking existing entries' file links.
However that does not seem to work on my install (EE 2.5.5 and Assets 2.1.2 - coming from 2.0.5 and hoping that upgrading would solve my problem), Assets just creates a new file with a and '-1' suffix in the filename
Any thoughts? rg, Tim
