Hello, This is caused by the fact that the default tags separators are " ,|" (whitespace comma and |). This can be changed by editing the TagClass in XWiki space. There are 2 fields for this class that you can change: Multiselect separators (for editing ) and Join Separators (for view). You can delete the whitespace from first field.

Importance: High I am having trouble with whitespace handling in tags (1.1.2 & 1.2RC2 on Windows 2003 and Windows XP locally - and even on xwiki.org itself). tag1|tag2|word3 word4 becomes tag1|tag2|word3|word4 and tag1|tag2|tag 3|tag 4 becomes tag1|tag2|tag|3|tag|4 I would consider this a bug - am I wrong? [I used the object properties in the object editor and the tag dialog box in page wiki edit mode with the same result]
