@BJ Hargrave,
Yes, I just tested rearranging the items listed in -runbundles to make sure
the ones that should be loaded first are. The problem remains.
@Raymond Auge,
I'm having a hard time understanding your response. I think I generally
understand what you're saying, but I don't know what to look for as far as
what should specifically be in the set of requirements/capabilities for
this use case. But I think the essence of your response is that if the
requirements and capabilities are not properly configured in the bundles
then the bundles wont even resolve properly much less activate properly?
I'm quite certain that I have properly configured the
requirements/capabilities in the media player bundle which depends on the
dynamic weaving bundle, otherwise I don't think loading the MP3 file would
work properly from the gogo shell, which it does. I just don't understand
why it works from the shell but not from the GUI.
In case it helps, here is the output of listing the installed bundles in
the framework. I'm assuming that since the ASM, Util, and Dynamic Weaving
bundles are loaded first that the start level configuration is not required
(as indicated in BJ's response).

However, if you issue the following command at the gogo shell you get:
G! mp3:load "/home/ehuntington/projects/research/Tracks/AG1001/AG1001-01 -
Cat Stevens - Wild World.mp3"
mp3:load "/home/ehuntington/projects/research/Tracks/AG1001/AG1001-01 - Cat
Stevens - Wild World.mp3"
MP3Player run entered.
load: AG1001-01 - Cat Stevens - Wild World.mp3
state = PlayerState.INITIALIZED
After doing this you can then either click the play button in the GUI or
use the gogo command "mp3:play" and the song plays as expected.
What am I missing? I just don't understand why loading the mp3 file works
as expected when using the gogo commands but not from within the gui.
