Hi, Using the iPOJO API you can use 'setFilter' to update the LDAP filter of a dependency (DependencyModel.setFilter). When changed the set of bound services is recomputed. Be aware that it may lead to an invalidation of the instance if no providers match the new filter.
What we did in the past is to develop a handler receiving the new properties, computing the new filter and applying it to the targeted dependency.
