Did you add the #theme function to hook_theme? #theme should work the same. I don't believe there were any changes to how it is handled in drupal_render.
Thanks for the quick reply, but now I'm confused. With regard to registering my theme function, no, I didn't realize I needed to do that. Is this necessary for the FAPI to call a theme function that is referenced in the $form array? IOW, just declaring the function in the $form array doesn't imply that it should be called?
I went to the hook_theme documentation, but I'm unclear on how those registration parameters apply to FAPI clients; the documentation seems to speak from the viewpoint of the theme writer. I'm not writing a theme, just needing to wrap form elements into a table from the drupal_render() call. I embed class and ID attributes in the table which the theme can modify for aesthetics -- IOW, my module only applies the document structure elements without regard to their cosmetics at display time.
Am I taking the wrong approach to this?
FAPI and the theme layer are not the same... A theme function must be declared in hook_theme() in order for theme() to call it. FAPI simply calls theme() with the $element.
