[jboss-user] [JBoss Seam] - DataModel: Row is not available

[fabricio.lemos]

I had this DataModel bound to the conversation scope


  | 	@DataModel
  | 	public List<Step> getStepList(){
  | 		return useCase.getSteps();
  | 	}
  | 

All worked just fine until I changed the association type from List to Set and updated the code to:


  | 	@DataModel
  | 	public Set<Step> getStepList(){
  | 		return useCase.getSteps();
  | 	}
  | 

Now the page does not show a new row if a Step is added to the collection. And the console display
ERROR [HtmlTableRendererBase] Row is not available. Rowindex = 0

If I end the conversation and access the page again, the new Step is displayed.

What can be wrong?

Seam version: 1.2.1

thanks in advance,
Fabricio Lemos
