Hello,
Don't know if it's a bug or an evolution, but after migrating my xwiki to 1.2.2, when I attach a new file to a page, all spaces characters are trimmed from the name. I didn't found anything about that in Jira. For example "My Doc Attached.doc" gets renamed to "MyDocAttached.doc".
http://jira.xwiki.org/jira/browse/XWIKI-2090 http://jira.xwiki.org/jira/browse/XWIKI-2087 The use of the clearName method for attachment names is a temporary fix until the resolution of all our encoding issues.
I see at least one issue coming from this : if you attach the same file it's not considered the same because it's renamed. Your existing links also link to the previous version, and it's not easy to find by end-user. And anyway you don't want the file to be renamed when attached …
Yes this is a drawback of this fix. JV.
