Change this to:

from FramePanelPage1 import FramePanelPage1
from FramePanelPage2 import FramePanelPage2

And this to:

      _custom_classes = {'wx.Panel': ['FramePanelPage1', 'FramePanelPage2']}

Yes Boa will willingly replace with ANY value you defined in the
custom classes (they are handled as strings).

Change your code as I showed above so that the actual class you
use is visible to Boa. It works for me.
