Nonetype is not iterable - returning from the gm to the mm

[DesertFox]

Recently, returning to the Main Menu from the Game Menu leads to the following traceback error.

Code: Select all

I'm sorry, but an uncaught exception occurred.

While running game code:
TypeError: 'NoneType' object is not iterable

I'm afraid I'm not very good at reading tracebacks so I'm not certain what the exact issue is here. The only recent difference I've made that may be causing this is inside the Navigation menu with the following. I wanted to have a different navigation menu dependent on its being accessed from in-game or the main menu:

Code: Select all

screen navigation():
    if main_menu:
        add "menuback"
    else:
        null
    frame:
        style_group "yesno"
        xfill True
        yfill True
    hbox:
        style_group "mainmenu"
        xalign 0.5
        yalign 0.92
        textbutton _("R E T U R N") action Return()
        null width 25
        if main_menu:
            null
        else:
            textbutton _("S A V E   D A T A") action ShowMenu("save")
        null width 25
        textbutton _("L O A D   D A T A") action ShowMenu("load")
        null width 25
        textbutton _("C O N F I G U R E") action ShowMenu("preferences")
        null width 25
        if main_menu:
            null
        else:
            textbutton _("T I T L E") action MainMenu()
        null width 25
        textbutton _("W E B") action OpenURL ("http://war-girl.com/")
        null width 25
        textbutton _("Q U I T   G A M E") action Quit()   

Any thoughts?

[Queex]

Not sure, but I think the nulls in there are the problem.

Instead try:

Code: Select all

        if not main_menu:
            textbutton _("S A V E   D A T A") action ShowMenu("save")

And the same for the other use of null.

[DesertFox]

That didn't do the trick, I'm still getting the traceback :/

[PyTom]

It's not the nulls - it's more likely that a None is somehow making it into the text rendering code. If you can't figure out from where, send me the code and I'll try to figure out what's going wrong.

[DesertFox]

Never mind, I found out what it was. For some reason I had an 'insensitive_color None' in the style group for the main menu buttons. Not sure how that got in there.

Thank you for the help!
