CreateChildren is the end of the stack trace? That doesn’t make sense. When
does it really get called?

SCENARIO:
Flex 4.5.1 mobile application targeting Android and iOS (no pad) only.
Works flawlessly on desktop emulations (all profiles) and on all Android
devices.
Started testing on iOS 3GS and I get the following error (only top-most
relevant lines are displayed) after the app hangs at the splash screen:
TypeError: Error #1009: Cannot access a property or method of a null object
reference.

COMMENT ON DEBUG OUTPUT.
I have made custom skins based on Adobe mobile skins. The custom skins have
F prepended to the Adobe mobile skin name. They are clones of the mobile
theme skins with my custom art etc as hard-coded ActinScript and FXG skins.
I have four very narrow range nonCFF embedded fonts declared appropriately at
the top. My data renderers use _sans.
When I mentally step through the code starting at UIComponent line 12739 I
don't see the problem(!?!). There are no NULLS.
I understand that the relevant lines of code causing the problem are mostly for
debug purposes, but I just can't see what the problem is. All the way up to
the call to SystemManager.callInContext() there are no NULLS that I can find
checking the variables -- save for the `this` argument which is NULL as it
should be.
The fonts are in the registry as:
embed_font_cine_bold_normal_899163827;
embed_font_cine_medium_normal_597874558;
embed_font_serpe_bold_normal_1790603002;
embed_font_serpe_medium_normal_1688454721;
:-/
Alex, should I just write an uncaught error handler for this?
Regards,
Naga
