Hi Shane, thanks for your time.

While it obviously is a good idea to switch to Integer where null-references are wanted, the fact that i used an int initially is a good indicator, that null isn´t that useful ;)
I do not see, what is wrong with using primitives here. The problem was that the initialization must be done via Seam like this:

    @Out(scope = ScopeType.SESSION)
    private int documentListPageSize;

    @Factory(value = "documentListPageSize", scope = ScopeType.SESSION)
    public int createDocumentListPageSize()
        return UIListHelper.DEFAULT_PAGE_SIZE;

The problem was that create=true was missing on @In.

While this works fine now (yep, with *int*s), it looks like doing this programmatically is quite more readable, than the above use of Annotations:

    private SeamSessionLocal pageSize = new SeamSessionLocal("documentListPageSize",

where SeamSessionLocal is a wrapper to an Attribute of the SessionContext.

Well kind of flavour, i guess.

Thanks again Shane.
