I think it's my fault... I've checked in a fix. Basically: The mechanism for has changed slightly in version 5.0: it now uses the class mechanism for keeping track of the user library. The user library is a class and when vergil loads it instantiates a single instance of the class. In this case, the actor was being saved in the instance, but not in the class, meaning that it was not being saved back to the file. If you download the source, you can patch the code:
Below is an updated patch, or you can download BasicGraphFrame.java and replace$PTII/ptolemy/vergil/basicl/BasicGraphFrame.javacxh@maury 162% diff ~ptII/ptweb/ptolemyII/ptII5.0/ptII/ptolemy/vergil/basic/BasicGraphFrame.java . 156c156 < @version $Id$ --- > @version $Id$ 1205c1205,1206 < CompositeEntity library = (CompositeEntity) configuration.getEntity( --- > CompositeEntity libraryInstance = > (CompositeEntity) configuration.getEntity( 1208c1209 < if (library == null) { --- > if (libraryInstance == null) { 1215c1216,1224 < configuration.openModel(library); --- > // Note that the library in the configuration is an > // instance of another model.

Then paste whatever you want in. On a related note, while trying this out, I ran across a nasty bug I haven't seen before: If you have an unnamed composite actor it's name is the empty string. If you use the dotted notation to access something inside it (e.g., the _location attribute), then it's name is "._location" unfortunately, names that begin with a dot are 'special' and are interpreted relative to the toplevel. You can see this problem if you open a new model, do graph -> Save Model in Library to save to the library, and then try to drag it in the library. Vergil tries to reference it's _location attribute, but fails because of the above.
