Richard Kennard commented on FORGE-393:
---------------------------------------

Okay we decided work around this at the JSF layer instead (see forgeview:asList in the generated scaffolding)

> It would be cleaner for the UI if the persistence plugin could base its collections on Lists, rather than Sets. This is because JSF's built-in h:dataTable needs something with a defined ordering.
> It is possible to work around this in various ways, such as adding special getters to the view Bean, but I think for the sake of clear, concise code the easiest way would be to make the generated code be a List.
> For example:
> 	@OneToMany
> 	private List<Grocery> groceries = new ArrayList<Grocery>();
> 	public List<Grocery> getGroceries() {
> 		return this.groceries;
> 	}
> 	public void setGroceries(final List<Grocery> groceries) {
> 		this.groceries = groceries;
> 	}
