Cannot save any modification for other selection than Default in Configuration Scope

[addison74]

I just installed OpenMage v20.0.6 from scratch then I accessed the Backend. To reproduce this issue go to System -> Configuration.

From left side choose a "Configuration Scope" from the list then press [Save Config] button. Here are the results:

Default Configuration

Main Website

Default Store View

Now let's delete this folder /app/code/core/Mage and replace it with the one from OpenMage v20.0.5. Here is the result:

In conclusion "something" in bad happened from 20.0.5 to 20.0.6. There are not many files changed between versions and I don't have time to debug. I will evaluate which files could generate this issue and I hope to find them quick.

BTW reverting this folder to its previous version I was able to use again the Template Hints feature in Frontend.

This is the file responsible for this issue:

lines 628 - 635:

        switch ($this->getScope()) {
            case self::SCOPE_DEFAULT:
                return (bool)$field->show_in_default;
            case self::SCOPE_WEBSITES:
                return (bool)$field->show_in_website;
            case self::SCOPE_STORES:
                return (bool)$field->show_in_store;
        }

Replace bool with int.
