Incorrect behaviour of category checkboxes

[Andriy Petruk]

update-manager 1:0.156.14.9, Ubuntu 12.04.1 LTS

Step 1. Select all items in category of updates (e.g. "security updates") manualy not using category checkbox
Step 2. Category checkbox expected to be selected after all items of category are selected, but it remains unchecked.
Step 3. If category checkbox is clicked - selection of all items is inverted.

<https://wiki.ubuntu.com/SoftwareUpdates#expanded>: "The state of the checkbox should reflect and change the state of the update checkboxes in that section: ☑ checked if they all are, ☐ unchecked if none of them are, and ⊟ indeterminate otherwise."

It looks like we need an expected behavior description.

Simple: the category checkbox is currently toggling all the children items, when its new state should be propagated to all children:
* selecting a category results in all children being selected
* de-selecting a category results in all children being de-selected (cleared)

Optionally, a third (gray) state would leave the individual selections as they were last set manually, but I guess that depends on the widget used.

I believe I covered this with the redesigned updates list. Testing it from bzr trunk, it seems to be correct now, both with category headers and with application groups. Can anyone else confirm that this is solved in Raring?
