That's correct. The data is stored in a map in session scope. This is an
attempt to cheat the complexity of the UIData component. What the clayForEach
component does is creates a naming container for each iteration. It actually
creates a grid of components versus the fly weight pattern that the UIData
uses. The data from the "var" attribute is organized in a map in session scope
and the managed-bean-name symbol injects the prefix binding to the map
therefore the complex decode in the UIData is not required. The clayForEach is
not a decendent of UIData. It's just a dynamic way to create a grid of JSF
components that have a strategy for binding.
The clayForEach is a "RUNTIME" uses of the clay component so this setup only
happens when the view is created. I think that is what is causing your
problem. You need the view to be recreated each time you select a race. I
would try adding a navigation rule back to the same page from the command that
is associated with selecting a race.
If that doesn't work, I would suggest using the tomahawk dataList component.
The clayForEach is a kluge in comparison.
Example of the dataList:
<span jsfid="t:dataList" id="data1"
styleClass="standardList"
var="person"
value="[EMAIL PROTECTED]"
layout="simple"
rowCountVar="rowCount"
rowIndexVar="rowIndex" allowBody="true">
<span jsfid="outputText" value="#{person.firstName}"/>
<span jsfid="outputText" value="#{person.lastName}"/>
<span jsfid="t:htmlTag" value="br" rendered="#{(rowIndex !=
(rowCount - 1))}"/>
</span>
