Re: Sortable DataTable in Tomahawk...

[mjovanov <mi...@jpmchase.com>]

I am experiencing a very similar issue; I am working with a very complex
scenario using Tomahawk dataTable component, requiring paging (through
sub-selects), sorting, dynamic columns (number and type)...  I originally
had the managed bean scoped to session but am now trying to change that to
request since I am working with large data sets (modeling my solution after
the examples listed on Working With Large Tables:
http://wiki.apache.org/myfaces/WorkingWithLargeTables)  However now that I
finally got most of it to work, all of a sudden I can?t get it to sort.  It
looks like JSF in not calling the setSortColumn() method on the managed bean
with the correct argument (it is actually calling it only once and with the
default value; I noticed that before, when my managed bean had session
scope, setSortColumn() was actually called twice: once with the old value
and then again with the new value).  Here is short sample of my code:

  <t:dataTable id="dataTable"
  	styleClass="recordSetTable"
  	headerClass="resultSetTableHeader"
  	rowClasses="cellDataAltRow,cellDataFirstRow"
  	renderedIfEmpty="false"
  	value="#{workbenchForm.dataModel}"
  	preserveDataModel="false"
  	rows="25"
  	var="row" 
  	sortColumn="#{workbenchForm.sort}"
  	sortAscending="#{workbenchForm.ascending}"
  	preserveSort="true" >
  	<t:columns id="columns" value="#{workbenchForm.columns}" var="column"  >
  		<f:facet name="header">
  			<t:commandSortHeader columnName="#{column.label}" arrow="true"
styleClass="cellDataHeader">
  				<h:outputText value="#{column.label}" />
  			</t:commandSortHeader>
  		</f:facet>
  		<h:outputText value="#{workbenchForm.columnValue}" />
  	</t:columns>
  </t:dataTable>
  
Has anyone been able to figure this problem out?  Could it be a bug in the
Tomahawk component lib?
