User install product C. Next step, user gets a new version of package B (just download from vendor site, for example). And try to install it. But for some reasons package A depends from particular version of package B. So, it is pleased if user will see some message with warning like "other products are installed which depend on that product". and he may decide to do or not to do this upgrade.
And how i think, such logic can be realized via Requires/Provides Elements from Dependency Extension. But there is lack of information about this option/feature. Anyway, if there is another approach to achieve this i will appreciate for any clues or explanations. regards, Valery. ------------------------------------------------------------------------------ Download BIRT iHub F-Type - The Free Enterprise-Grade BIRT Server from Actuate!
