When I've done this, I wasn't using the feature tree control, but
check boxes or radio buttons to select features. I had AddLocal/Remove
control events on the control to adjust the feature selection, but
since I was using a checkbox or radio button I also had properties
of my own that reflected the feature choice.
If you are requiring MSI 3.0 or later, then the selection tree control
publishes events that can notify you when the feature selection states
change. You should be able to use the ControlEvent table for the
selection tree to set your own property indicating that a particular
feature has been selected for installation and then use that property
in a condition on your Next button to manage the dialog transition.
I haven't experimented with this, so I don't have specifics on how
this works with a SelectionTree control, but the docs indicate that
the control communicates by setting properties that indicate what the
user did with the control before it processes the ControlEvent table
for that control.
