I have a question regarding a feature and the webparts. Basically recently i noticed that when i deploy a webpart with my solution and it is bound to a feature on site collection scope, when it is deployed the feature is automatically activated so when i'm in page i can see amongst all the webparts to choose, i see my own web part and i can add it to the page.

So I add the web part to the page and it works ...

Now i go and deactivate the feature, what i see is that the web part is still present on the page AND i can still ADD the web part to any page in the site collection, how come?

Maybe i do something wrong or is it normal behaviour and have can i make sure that when i deactivate the web part it is not anymore available in the web parts catalog?

Any input is welcome, i need a clarification on this one ...
