Re: [equinox-dev] Service component deployment fails into a running Equi

[Alex Blewitt <alex.blewitt@xxxxxxxxx>]

Do you have an optional import for the package name? 

If you do, and that bundle starts first, then it won't be wired to the package. If you start up the bundle containing the package first, then start up the provider, it will resolve the list of optional imports. Once started, even if an optional package is added later it's not added to the existing running bundle's package list. If you do a 'refresh' on the service provider, does the problem go away?
