[jboss-user] [JBoss Seam] - Multiple @DataModelSelection fields error

[asookazian]

Are the @DataModelSelection and @DataModelSelectionIndex annotations only useful when user clikcs on commandLink or commandButton in a dataTable?  If so, how should I get and pass the currentRowNum of a dataTable to a SFSB method when a a4j:form in a rich:modalPanel is submitted (fire Seam remoting javascript function onclick to set the value in an instance variable in the SFSB prior to submission of the form)?

I'm trying to use @DataModelSelectionIndex in conjunction with @DataModelSelection and am getting the following stack trace:

@DataModel
  | private List myAuditList;
  | 		
  | @DataModelSelection
  | private Object myAuditListSelection;
  | 	
  | @DataModelSelectionIndex
  | //this is the row number of the underlying collection
  | private int currentRowNum;
