[p2-dev] Feature Versions and Custom Actions

[Deric Panet-Raymond <deric@xxxxxxxxxxxxxxxxx>]

Hello,

I'm working on a P2 install which requires the execution of an installer 
binary as part of the feature installation.  I have managed, with the 
help of the archives of this list, to get the custom action running and 
the executable to be run.  I am now trying to work on the uninstall side 
of things, where the user reverts back to an older version and I'm 
running into some problems.  When I do an install, then update and then 
try to revert back to the original installed version, Eclipse is 
completely removing my feature.

My current setup is

BinaryFeature - contains the executable to be executed
HolderFeature - contains the plugin which has the custom action plug
CustomActionPlugin - ProvisioningAction class which finds the executable 
and runs it
UpdateSite - Contains the Binary and Holder features

I'm wondering why my feature is being completely removed when I do the 
revert, I would have at least expected the originally installed feature 
to be re-added.  Is it because the BinaryFeature doesn't have a plugin 
associated with it?

Any hints or tips would be greatly appreciated.

Thanks.

Deric.
