Magento: theme fallback hierarchy question - magento

Can someone verify what I think is what's happening with Magento's fallback theme hierarchy.
The final fall-back point is the /base/default/ theme.
Within your interface/package (they are the same things right?), your default theme is selected at, from the Magento admin page, System->Configuration->General->Design->Themes->"B" ("B" is an example name of the theme).
On top of your default package theme, you can select an active theme from System->Design->"A".
So with this setup, Magento will look into "A" first, then in "B", then finally resort to base/default if neither A or B has files it needs.
Correct or no? TIA!

Sorta.
The fall-back hierarchy in Magento CE v1.4+ and EE v1.8+ is as follows.
Look for requested file in:
app/design/frontend/custom_package/custom_theme/
skin/frontend/custom_ package/custom_theme
If not found, look for requested file in:
app/design/frontend/custom_package/default
skin/frontend/custom_package/default
If not found, look for requested file in:
app/design/frontend/base/default
skin/frontend/base/default
If not found, a rendering error will occur.

I will do my best to clarify some points for you.
If you are not using a child theme, magneto will use /base/, however if you have a child theme active, magneto will use your custom theme files.
For example, If your new theme file has a header.phtml file but not footer.phtml, Magento will automatically fall back to the base. this is why its never smart to edit core files

How to add Magento extension in other theme except default

I want to add extension - All Category Product Carousel in my Magento Website and it has RWD theme.The components of the extension are by default installing in:
app/design/frontend/default/default/layout
app/design/frontend/default/default/template
skin/frontend/default/default
I have moved the components in my theme folder i.e. RWD, and components are now in the following folders:
app/design/frontend/rwd/default/layout
app/design/frontend/rwd/default/template
skin/frontend/rwd/default
But after this also the extension is not working. I am new to Magento so does not know much things about it. Does anything else be done?
The products are there but css and js is not getting applied on them. The data is showing like: Please View Here
You can paste your extension key here. Now you can check if you have copied all the files to RWD.
The extension tell to insert below block in cms page. Include it in your cms->home page.
{{block type="pcarousel/pcarousel" pcarousel_id="carousel id" template="pcarousel/pcarousel.phtml"}}
After that navigate to system->permission->blocks->Add new block and add the type pcarousel/pcarousel there and allow it.
The css and js files were not loading in the main page, have added them externally. Now working

Magento loading base theme instead of downloaded theme

Im trying to install a theme on magento 1.9. Have copied all files into the correct places.
Under System -> Configuration -> Design -> Themes I have set templates, skin, layout and default all to the theme name.
The problem I think i am having is 'Current package name' It was originally set to 'rwd' and when it is set to this it loads the default 1.9 magento theme. However when i change this to 'default' it loads the magento base theme. If i set the package name to the name of the theme it also loads the base package.
Skin Directory Structure
Design Directory Structure
Did you check your custom design? Access: System > Design
just cross check following configuration with your configuration.
Then clear cache and check.

Magento Theme Hierarchy

Currently I am moving the theme file from Default/XXX to XXX/default . From
http://www.magentocommerce.com/knowledge-base/entry/magentos-theme-hierarchy
I found out that Magento searches the file in following sequence:
Package/theme->Package/default->Base->default.
Is it possible to make it search the theme like this: Package/theme1->Package/theme2->Package/default->Base->default?
Besides that, will the magento still be loading the default/default theme?
Thx
Magento system will fall back the files using below order.
Using DEFAULT package with DEFAULT theme
1) app/design/frontend/{DEFAULT}/{DEFAULT}
2) app/design/frontend/base/{DEFAULT}
Using DEFAULT package with Custom theme
1) app/design/frontend/{DEFAULT}/{MY-THEME}
2) app/design/frontend/{DEFAULT}/{DEFAULT}
3) app/design/frontend/base/{DEFAULT}
If you are using the Custom Package with Custom theme.
1) app/design/frontend/{CUSTOM-PACKAGE}/{MY-THEME}
2) app/design/frontend/{CUSTOM-PACKAGE}/{DEFAULT}
3) app/design/frontend/base/{DEFAULT}
These above order only magento files are fallback.
Old question but as I stumbled across this I would like to add the newest fallback hierarchy.
Since 1.9 you can define the fallbacks in a theme.xml in your theme folder. See http://alanstorm.com/magento_parent_child_themes for further information.

Magento's theme hierarchy: base/ vs default/

In this material I read about themes in magento.
I also talks about default/default folder, but it doesn't specify clearly which is on top of which.
So, if a have mythemepackage/default, default/default and base/default, is default/default reached while getting falledback from mythemepackage to base?
[EDITED]
NO,
If you have below package/theme
1. mythemepackage/mytheme
2. mythemepackage/default
3. default/default
4. base/default
and you have set the package to mythemepackage and default theme to mytheme.
Then Magento first check in mythemepackage/mytheme folder and if not found then check in mythemepackage/default and if still not found then look in base/default.
If not found, a rendering error will occur.

Magento Extensions: How do I tell my build system where the active theme is located?

My extremely simple build system for Magento needs to deploy some extension frontend code into the appropriate theme folder. But I don't know how to get it to find out which folder to put the files in at build time. Anyone know how to get this data out of Magento?
Put your code in the base/default theme (default/default prior to version 1.4, or both just to be sure) and it will be available to all themes thanks to inheritance.
Each store within Magento can set it's own theme so you might have more than one to consider. Also certain pages like CMS, category or product pages can choose their own theme to override the store and global settings.
To find the package and theme that corresponds to the folder app/design/frontend/PACKAGE/THEME use;
Mage::getStoreConfig('design/package/name', $storeId)
and;
Mage::getStoreConfig('design/theme/default', $storeId)
If calling from a PHP file external to Magento then you'll need to include 'app/Mage.php'; first. The $storeId value can be either an int as used internally or the store code saved in System > Configuration > Manage Stores - there is usually at least a "default" value.
