Issues have been encountered due to deriving UIData without maintaining the expectation of iterative children being contained within UIColumn derived children. Solutions are under investigation.
--------------------
Ultimately derived by UISeries which has been designed to work around this limitation.

ICE-7822 - Initial commit of ace:list & ace:listControl components, and showcase examples thereof.

The development of this component was hampered by problems including:

• UIData dependency on child column components
• Attempted to solve by having a custom list of children that would mask an implicit column child in some situations
• Attempted to inject column child into hierarchy in TagHandler event
• Investigated complete override of TagHandler / Composite Component
• Settled on UISeries implementation that is an overriden UIData meant to work without UIColumns

• Difficulties in addressing the items
• Have to use indexes despite reordering and new item introduction

• Planning client-side / server-side interaction between features
• Need to adjust item index values through list of reorderings to record pre-reorder indexes so that feature decoding can be performed in-order on the server
• For the client side to be able to migrate items between lists it needs to be sure on the server the operations are performed in the same order (JSF decodes as a tree, this would require alot of effort), or objects addressed uniquely, since neither is possible without further supporting code, migrations must visit the server.

• Investigated multiple drag jQuery component modification

• JSF ids need to stay in place, however the underlying JQuery component moves them.
• Elements need their IDs dynamically updated on the client to preserve the layout of the JSF ids. If the JSF ids are moved DOM diffed updates may update unexpected regions of the page, as the client DOM no longer is addressed similarly to the server dom.

As of svn rev # 28960 the multi-list demos on showcase no longer function. You can't move the selected items between lists.
