Richard,
I am currently downloading the osgi book as I write this. But going back
over what I did. I added the id's again to @Bind, and @Unbind, when I did
this. it now adds a TidgetSaasmDevice, but only 1, then only until i close
the GUI driving these binding functions do the rest get added before it[GUI]
is completely closed.
I am confused as to why the GUI added them correctly (except for the copy)
when I had the @Requires, but not now?
I apologize for all the questions, I am relatively new to the felix
framework.
