Note that by default the "sam" theme is used, but the user can control this via the

<context-param>
		<param-name>org.icefaces.ace.theme</param-name>
		<param-value>xxx</param-value>
</context-param>

...config. parameter, including setting it to "none".

See http://www.icesoft.org/wiki/display/ICE/ace.theme for details.

1. Nothing to do with classpath or package or reflection as stipulated in the Description. These are JSF 2 resources in META-INF/resources, not anything like localization message bundles.
2. Seems there is no magic API to get enumeration of resources. Must use low-level jar/zip file scanning? (There is only API for creating a resource from a known path, i.e. lib dir + name/path. The Mojarra implementation ultimately just does jar/zip scanning as well.)

First working prototype: http://screencast.com/t/lkfN8lIRzcjJ.

Scanning of theme CSS resources based on ideas in this article: http://bill.burkecentral.com/2008/01/14/scanning-java-annotations-at-runtime/, using class loader and JSF getResource(s) and createResource(s), plus some pattern matching. (No re-invention of my own as in the beginning, so performance can't be any worse than JSF is already doing. See also com.sun.faces.application.resource.ZipDirectoryEntryScanner#ZipDirectoryEntryScanner.)

Theme switching based on study of some code in Super-Theme-Switcher.

Processing of org.icefaces.ace.theme and determination of theme names same as in org.icefaces.ace.renderkit.HeadRenderer, with added checking for backing bean value.

Need to modify this to cache the resolved list of themes into the Application scope so it only gets loaded/resolved once per application.

[2013-02-28 12:14:21 PM] Mark Collette: FacesContext.getCurrentInstance().getExternalContext().getApplicationMap()
[12:29:52 PM] Ken Fyten: Current theme will be stored in the session scope.
[2013-02-28 12:28:38 PM] Ken Fyten: Head renderer for theme needs to be modified to check if the selected Theme has changed and use it instead of the default theme.

All requirements noted above done. Showcase build changed to include all theme jars. Theme switcher dropdown list added to Showcase: screenshot-02.png, screenshot-03.png

[3:19:52 PM] Ken Fyten: an ace:ajax event that could be used to submit it when it changes

[10:39:20 AM] Ken Fyten: themeSelector needs to respect Theme Roller styling, just like the ace:simpleSelectOneMenu does.

Also:

1. use div as in simpleSelectOneMenu, not span
2. remove theme value from backing bean

All the above done. (For styling, added exact same style classes as simpleSelectOneMenu.)

For styling, let's keep this rendered inside a SPAN and just not attempt to use the ThemeRoller rounded-corner styling due to negative interactions with the natively rendered drop-down button which can vary between browsers.

Done.

M: C:\svn\ossrepo\icefaces3\trunk\icefaces\ace\component\src\org\icefaces\ace\component\themeselect\ThemeSelectRenderer.java#33940

Introduced an ant property to flag inclusion or exclusion of theme jars in build. (Previously always included.)

M: C:\svn\ossrepo\icefaces3\trunk\icefaces\samples\build\common.xml#34132

Removed the none option from the selector, as per Ken's request. (cf. original requirement.) Note: if "none" is specified (in value attribute or (no value and set in context param.)), the default of "sam" will be used.
