question: public void normalize ( ) { StringBuilder sb = new StringBuilder ( ) ; for ( String v : values ) { sb . append ( v ) ; } values . clear ( ) ; values . add ( sb . toString ( ) ) ; compacted = false ; }
target:  This method convert the list of values again into a only one value.  After that the attribute is not compacted. TODO: what about entities, now are just appended "abcd...&20;...cc"
