INSTALLLEVEL Doesn't Install a Feature
I have two features:

        <Feature Id='BaseProductFeatures' Title='Feature 1' Level='1'>
            <ComponentRef Id='WebAppVDirComponent'/>
			<ComponentRef Id='someVDirComponent'/>
			<ComponentRef Id='anotherWCFVDirComponent'/>
			<ComponentGroupRef Id='group_IMPORTFOLDERFILES'/>
			<ComponentGroupRef Id='group_WINSERVERFILES'/>
        </Feature>

		<Feature Id='SMSGWFeature' Title='Feature 2' Level='2'>
			<ComponentGroupRef Id='group_SMSGWWEBAPPFILES'/>
		</Feature>

Before the install, I change the INSTALLLEVEL to 2 using a Custom Action:

        [CustomAction]
		public static ActionResult ChangeInstallLevel(Session session) {
		    session["INSTALLLEVEL"] = "2";
		    return ActionResult.Success;
		}

The value gets set, but Feature 2 (SMSGWFeature) does not get installed. Why is that? I don't see any of the Components in the ComponentGroupRef, group_SMSGWWEBAPPFILES, get installed in the directory I would expect to see them in. But the installer will work if I set the Level of Feature 2 (SMSGWFeature) to 1.
