Comment:

 Replying to [ticket:1391 pls]:
 > In the vector layer properties dialog it is possible to change the
 values of the attributes I chose for a Unique Value classification; this
 is particularly useful if you have non-meaningful values names in the
 attribute field used for the classification. The problem is, when the
 modification is applied to the layer, all the points pertaining to the
 modified value's class disappear from the layer.

 You probably edited the attribute values instead of adding a description
 on the right.

 Changing the value means that you want features with the value you enter
 in the classification field to look like the features with the original
 value looked like. Moreover you don't loose the class for the original
 value and therefore those features won't be rendered anymore.

 Editing the is meant to add classes that do not yet have features for.

 BTW r10986 adds a default class that renders classless features.

 I'm not sure if I understood your problem correctly.  Feel free to reopen,
 if I didn't.
