> While sorting column id is being evaluated as part of expression.
> Sorting in column in scrollableDataTable is working only in case column id attribute can be evaluated as a property of a row of  rich:scrollableDataTable's "value" attribute.
> In the demo sorting is working because column id matches the property of the table row object :
> <rich:scrollableDataTable rowKeyVar="rkv" frozenColCount="1" height="400px" 
>                 width="700px" id="carList" rows="40" columnClasses="col"
>                 value="#{dataTableScrollerBean.allCars}" var="category" sortMode="single"
>                 binding="#{dataTableScrollerBean.table}"
>                 selection="#{dataTableScrollerBean.selection}">
>                 <rich:column id="make">
>                     <f:facet name="header"><h:outputText styleClass="headerText" value="Make" /></f:facet>
>                     <h:outputText value="#{category.make}" />
>                 </rich:column>
> ...
> value="#{dataTableScrollerBean.allCars}" var="category" 
> rich:column id="make"
> "category" here does have "make" property, column is sorted on outcome of #{category.make} expression, but if column id changed for something else, "notAProperty" for instance, the column wouldn't be sortable anymore.
> Further, if column id is set to another property, for example:
> rich:column id="someProperty" 
> and expression "#{category.someProperty}" can be evaluated - the column will be sorted by "#{category.someProperty}" no matter what outputText value for column is. 
> This seems to be the source of other related issues like Sorting feature doesn't work for dynamic columns(rich:columns) https://jira.jboss.org/jira/browse/RF-2413. That bug is marked as closed, but I don't see how I can provide correct column ids for dynamic columns and not really sure dynamic columns issue was resolved.
