> I'm coding at pax-wicket right now and find the following "problem":
> In the following features.xml...
> {code}
> <!-- Departmentstore example suite provided with paxwicket -->
> <feature name="departmentstore" version="0.6.0-SNAPSHOT">
> <feature version="0.6.0-SNAPSHOT">web</feature>
>
> <bundle>mvn:org.ops4j.pax.wicket.samples.departmentstore/departmentstore-model/0.6.0-SNAPSHOT</bundle>
>
> <bundle>mvn:org.ops4j.pax.wicket.samples.departmentstore.view/departmentstore-view-about/0.6.0-SNAPSHOT</bundle>
>
> <bundle>mvn:org.ops4j.pax.wicket.samples.departmentstore.view/departmentstore-view-application/0.6.0-SNAPSHOT</bundle>
>
> <bundle>mvn:org.ops4j.pax.wicket.samples.departmentstore.view/departmentstore-view-floor/0.6.0-SNAPSHOT</bundle>
>
> <bundle>mvn:org.ops4j.pax.wicket.samples.departmentstore.view/departmentstore-view-franchisee/0.6.0-SNAPSHOT</bundle>
> </feature>
> <feature name="departmentstore-basic" version="0.6.0-SNAPSHOT">
> <feature version="0.6.0-SNAPSHOT">web</feature>
>
> <bundle>mvn:org.ops4j.pax.wicket.samples.departmentstore/departmentstore-service-basic/0.6.0-SNAPSHOT</bundle>
> </feature>
> <feature name="departmentstore-alternative" version="0.6.0-SNAPSHOT">
> <feature version="0.6.0-SNAPSHOT">web</feature>
>
> <bundle>mvn:org.ops4j.pax.wicket.samples.departmentstore/departmentstore-service-alternative/0.6.0-SNAPSHOT</bundle>
> </feature>
> {code}
> ... I have the problem that both, departmentstore-basic and
> departmentstore-alternative depend on web AND departmentstore; but they
> "conflict" with each other. I know that we can't detect such a situation
> automatically BUT it would be cool to do something like the following
> {code}
> <feature name="departmentstore-basic" version="0.6.0-SNAPSHOT">
> <feature version="0.6.0-SNAPSHOT">web</feature>
> <feature version="0.6.0-SNAPSHOT"
> conflicts=true>departmentstore-alternative</feature>
>
> <bundle>mvn:org.ops4j.pax.wicket.samples.departmentstore/departmentstore-service-basic/0.6.0-SNAPSHOT</bundle>
> </feature>
> <feature name="departmentstore-alternative" version="0.6.0-SNAPSHOT">
> <feature version="0.6.0-SNAPSHOT">web</feature>
> <feature version="0.6.0-SNAPSHOT"
> conflicts=true>departmentstore-basic</feature>
>
> <bundle>mvn:org.ops4j.pax.wicket.samples.departmentstore/departmentstore-service-alternative/0.6.0-SNAPSHOT</bundle>
> </feature>
> {code}
> If I have departmentstore-basic install now and I do a...
> {code}
> feature:install departmentstore-alternative
> {code}
> ...something like the following should happen automatically...
> {code}
> features:uninstall departmentstore-basic
> features:install departmentstore-alternative
> {code}
> For one feature this is maybe trivial but think you 20 departmentstore
> implementations. This will require you to look up which is currently
> installed, uninstall it and then install the new one...
> WDYT?
