Hi!

I hope you can help me with this, I dont see what Im doing wrong, I have this code

[i]
class TableTeclasRapidas extends Table{
private String modelo =“”;
private Hashtable<Integer, TeclasRapidasDetalle> teclasRapidas;

    	TableTeclasRapidas(String caption){
    		super(caption);
    		this.setSelectable(true);
    		this.setWidth("250px");
    		this.addContainerProperty("tecla", Integer.class, 0);
    		this.addContainerProperty("plu", String.class, "");
    		int i =0;
    		while(i<10){
    			this.addItem(new Object[]{i,"123456"},i);
    			i++;
    		}
    	}
    	
		public String getModelo() {
			return modelo;
		}


		public void setModelo(String modelo) {
			this.modelo = modelo;
		}
    	
    	
    	public void deleteTeclasRapidas(){
    		System.out.println(this.getValue());
    	}
    	
    	public void addTeclasRapidas(int tecla, String plu){
    		
    	}
    	
    }

[/i]

I don’t see any particular problem with the table class at the first look at least. Are you sure that it comes from the table and is not just conincidence? I assume that you have set setImmediate(true) for the table to get selection change events. Such an event could carry a non-immediate event that causes the problem with some other component.

Hi, well It is the table, but I think It was my bad, you see I declare the table inside a formfieldfactory, in my original bean there is a field, and I wanted to the formfieldfactory return that table when it was found, and for some reason I couldnt interact with the table on that way( those errors are the prof), so I fixed moving out the table out of the form and the problem was solved.
