Recreate Page

[furmanOFF]

Hello i am trying to implement dynamic sections manipulation in my setup:
I have some number of predefined invisible sections.
After some manipulations on "components" page, one of invisible sections must become visible so i call e.g.:

code:
SectionSetText $SECTION "Hello"

Of course it doesn't show up on "components" page (page is shown right now) So i need to refresh it somehow!
I've tried to push "Back" button with

code:
SendMessage $BUTTON ${BM_CLICK} 0 0

and then press "Next" in same way (or call Abort in precreation of previous page).
But my setup crashes right after Back is pressed.

Maybe you know some WM_ Message that will cause components page to refresh?
Or i should add it to components treeView manually?

P.S. I know that i could do it with ListBox in nsDialogs but it will be without checkboxes
