[jboss-user] [JBoss Seam] - EL expression for accessing a set?

[jamesjmp]

Hi,
I wonder if there is an EL expression for accessing a set?
For instance, I´ve this objects:


  | public class AssetType implements java.io.Serializable {
  | 
  | 	private long idAsset;
  | 	private String type;
  | 
  | 	private Set<Instrument> instruments = new HashSet<Instrument>(0);
  | ...
  | 
  | public class Instrument implements java.io.Serializable {
  | 
  | 	private String securityName;
  | ..
  | 
In a xhtml I want to display the securityNameof the first item in the instruments  set.

Something like this, but it doesn´t work

  | #{assetType[0].internalOptionNumber}
  | 
In java, it´s easy, for instance to display all of them: (yeah, I know an iterator would be fine as well, this is just a sample way of accessing)

  |         public String getSecurityName() {
  |             System.out.println("getSecurityName - getInstruments size:"+instruments.size());
  |             String secName ="";
  |                 for( Instrument ins : instruments  ) {
  |                     secName = ins.getSecurityName();
  |                     System.out.println("SecurityName" + secName );
  |                 }            
  |             return secName;
  |         }
  | 
Any way to access a set from an EL expression?
thanks in advance!
