[protege-discussion] Error using Protege with Jena database - Invalid Frame Name

[Daniel E. Renfer]

I am trying to use Protege to access my data stored in a Jena database 
with a MySQL backend. I am able to load the data, but Protege creates a 
whole bunch of junk namespaces for me.

I have this namespace declared:

@prefix entry <http://mycyclopedia.net/entries/>

and all of my entries are named like:

entry:44

Protege will see the declaration, but it will create a whole bunch of 
new declarations like:

@prefix p437 <http://mycyclopedia.net/entries/44>
@prefix p434 <http://mycyclopedia.net/entries/341>
etc.

As you can see, the number in the prefix bears no relation to the actual 
URI. When I try to delete one of those declarations, I get the message:

Internal Error: java.lang.IllegalArgumentException: Invalid frame name:
Please see Java console for details, and possibly report
this on our OWL mailing lists.
http://protege.stanford.edu/community/lists.html
Your ontology may now no longer be in a consistent state, and
you may want to save this version under a different name.

The exception is:

SEVERE: Exception caught -- java.lang.IllegalArgumentException: Invalid

Is this due to the fact that my local name starts with a number, or what 
could be causing this? I have tried 3.2, 3.3.1, and 3.4beta all with the 
same results.
