Hiding component selection page prevents component selection

While creating my custom component selection page, I tried to hide the default component selection page. Unfortunately, this makes it impossible for the installer framework to pick up the selections.

The way I am currently forwarding the component selections is (pseudocode):
Controller.prototype.ComponentSelectionPageCallback = function ()
{
if (myCustomSelectionPage.component.selected)

{ defaultSelectionPage.selectComponent(component); }

else

{ defaultSelectionPage.deselectComponent(component); }

I am skipping the page by using
installer.setValue("enteredFromBack", "yes");
if (installer.value("enteredFromBack"))

{ installer.setValue("enteredFromBack", "no"); gui.clickButton(buttons.NextButton); }

else

{ installer.setValue("enteredFromBack", "yes"); gui.clickButton(buttons.BackButton); }

Not only is this ugly, it sometimes causes a graphical glitch where the component page is briefly shown.

Hiding this component page with
installer.setDefaultPageVisible(QInstaller.ComponentSelection, false);
makes it so that the maintenance tool thinks I installed every component.

I also can't seem to get the componet and set it's installed value on a different page
var myComponet = installer.componentByName("myComponentName");
myComponent.setUninstalled();
