Thank you for the quick reply Richard, To be honest, I did not know this could be done without the @Requires.
Although when I try without the @Requires, @Bind does not pickup any new tidgets at all. according to http://felix.apache.org/site/ipojo-reference-card.html @ "Configuring service dependencies in the instance configuration" It appears I need the @Requires with a matching (id) option. Unless there is something else that I am missing? Richard S.
