[richfaces-issues] [JBoss JIRA] Commented: (RF-4194) Sorting for rich:scrollableDataTable-rich:column not working unless column id attribute is set to a value that can be evaluated .

Sorting for rich:scrollableDataTable-rich:column not working unless column id attribute is set to a value that can be evaluated . --------------------------------------------------------------------------------------------------------------------------------- Key: RF-4194 URL: https://jira.jboss.org/jira/browse/RF-4194 Project: RichFaces Issue Type: Bug Affects Versions: 3.2.1 Environment: Tomcat 6.0, Mojarra 1.2_09-b02 Reporter: Valery Tcherepanov Assignee: Mikhail Vitenkov Fix For: 3.2.2 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.
