One of the key factors in this bug is that SWF is performing its own state saving and this is colliding with the persistent component tree maintained by ICEfaces.

A fix being investigated is as follows:

• move partialSubmit functionality out of the Servlet stack into a PhaseListener
• add state saving capability to UIXhtmlComponent

Note that the partialSubmit functionality cannot remain in the Servlet stack when standard JSF state saving is performed – the component tree does not exist prior to ViewHandler execution. An alternative possibility is to move partial submit into the ViewHandler, however, 3rd parth PhaseListener interaction is simpler, so it is better to leave less functionality in the ViewHandler.

Using the above fix, the SWF booking demo is functional up to "book hotel" including partial submit.

In the UIXhtmlComponent state saving, standardAttributes and elValueExpressions should detect when they reference Collections.EMPTY_MAP, and just save nulls. When they restore, they could go back from nulls to Collections.EMPTY_MAP. That way, after save and restore, they won't inadvertantly be referencing new, unique, empty maps, and take up more memory.
