Subject [configuration] Should we remove list splitting for attributes in XMLConfiguration?
Date Sat, 08 Sep 2012 15:11:44 GMT
Currently XMLConfiguration allows setting multiple values for an 
attribute node. (This is possible through the Configuration interface, 
but of course not supported by XML.) When saving the configuration it 
tries to encode the list as a comma-separated string. On reloading, such 
strings are split again.

The implementation of this feature is pretty complex because points like 
escaping delimiter characters have to be taken into account. I doubt 
that it works in a reliable way in all possible constellations. OTOH, I 
don't think that this functionality provides much value to users.

So, in short, I propose to remove this feature. I would change the 
implementation to check for attributes with multiple values when the 
configuration is to be saved. If such attributes are detected, an 
exception can be thrown.

Any objections?
