Re: [mylyn-integrators] Missing Factory to Externalize Tasklist

[David Carver <d_a_carver@xxxxxxxxx>]

Well, I've been using the Bugzilla connector as a template assuming that 
it has been completely migrated to the new Mylyn 3.0 api, but 
apparentely it is still extending and overriding implementations of 
AbstractTrask and AbstractRepositoryQuery.

One other odd thing I'm noticing is that the username and password for 
my connector is not persisting between restarts of eclipse.   All of the 
other information for a connector is there when you come back in, but 
the information for the user id and password aren't restored.
