Paul McMahan commented on GERONIMO-2248:
----------------------------------------

This is a good idea, I have made the exact same mistake that you described above :-)

Suggestion -- instead of listing all the child components how about instead providing very explicit feedback in the form of a prompt when the user attempts to shut down a component.

e.g.  user clicks the "stop" link for geronimo/system-database/1.1.1/car.  console responds "stopping this component will also cause the following components to stop : [list]  Proceed? yes/no".  this could be done with a javascript prompt or (if it looks better) in a new portlet screen.

This would accomplish the same goal while avoiding the UI issues listed above.  I'm also doubtful that just seeing a component's children listed will provide sufficient indication that those components will be stopped when the parent is stopped, especially to the novice or unattentive user.

> Applications portlets currently provide component status and links to start/stop/restart/uninstall.  They do not provide a listing of parent components and child components.
> If child components are listed, a user will immediatley know what all configurations will be stopped if a particular component is stopped.
> How is it useful?
> I have stopped " geronimo/system-database/1.1.1-SNAPSHOT/car" to test something.  Only after an error HTTP 404 was displayed next,  I realized that the admin console had a dependency on "geronimo/system-database/1.1.1-SNAPSHOT/car".  Had there been a Child Components listing next to "geronimo/system-database/1.1.1-SNAPSHOT/car", it would have avoided the surprise.
