a type containing more than on list of non-primitive type returns a NPE #761

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Creating a type which contains more than one list of a type you previously 
defined (non-primitive) generates an NPE.

Reproduction:
==============
drop dataverse kereno if exists;
create dataverse kereno;
use dataverse kereno;

create type page_info_type as closed {}

create type page_views_type as open {
        page_links: {{ page_info_type}}?,
        page_links_1: {{ page_info_type}}?
}

Returns null[]

Note that the definition below works fine:

drop dataverse kereno if exists;
create dataverse kereno;
use dataverse kereno;

create type page_views_type as open {
        page_links: {{ int32}}?,
        page_links_1: {{ int32}}?
}

What do you observe if we define a primitive type field, like this in 
page_info_type definition. Note that in Keren's example page_info_type does not 
have any fields defined inside it.

create type page_info_type as closed {id : int32}

create type page_views_type as open {
        page_links: {{ page_info_type}}?,
        page_links_1: {{ page_info_type}}?
}

The structure of a nested type page_info_type does not change anything.
The issue is triggered whenever a type (page_views_type) contains more the one 
non-primitive field of the same type.
Check out the reason in
