| Uninstallation of optional features problem (P2 API usage) [message #648560] |

I created a product composed of several features
Now I want to be able to uninstall some of the features from the running application : to allow this (or at least I hoped so) I customized the p2.inf file of the product definition project to mark the uninstallable features as optional :
requires.0.namespace = org.eclipse.equinox.p2.iu
requires.0.name = my.feature.name
requires.0.optional = true
Now when I run the uninstallation operation (using the P2 API), P2 gives me the following information feedback :
"my human readable feature name" cannot be fully uninstalled because other installed software requires it. The parts that are not required will be uninstalled.
the uninstallation operation performs without errors, and the feature is not uninstalled (what the previous message predicted).
Apparently marking the dependencies as optional is not sufficient. Any clue about how to solve this problem ?
Thanks,
Sun
