Hi, Sorry I reread my post... http://community.jboss.org/thread/174057 the title is correct but the text in the message is wrong. Sorry for the confusion. The issue I am experiencing now with the new prototype is that unbind is called before bind (on JBOSS OSGi). In a previous prototype on equinox (slightly different code) the bind method was called before unbind which is what I am expecting.

Hi Guiseppe, I'm a little bit confused. In http://community.jboss.org/thread/174057 you mention as the issue is that 'the unbind method is called after bind' but here you say that your original prototype called bind() before unbind(). Isn't that the same?
