ClassCastException for collection type

[GoogleCodeExporter]

This AQL will produce:
edu.uci.ics.asterix.om.types.BuiltinType$10 cannot be cast to 
edu.uci.ics.asterix.om.types.AbstractCollectionType [ClassCastException]

What am I doing wrong?

------------------------
drop dataverse foo if exists;
create dataverse foo if not exists;
use dataverse foo;

create type footype as open {
    entities: {
        text: string?,
        numbers: [int32]?
    },
    id: int64
}

create dataset foo(footype) primary key id;

insert into dataset foo({
    "id": int64("1"), 
    "entities": {
        "numbers": []}
    }
);

Raman pointed out my error:
drop dataverse foo if exists;
create dataverse foo if not exists;
use dataverse foo;

create type footype as open {
        entities: {
                text: string?,
                numbers: [int32]?
        },
        id: int64
}

create dataset foo(footype) primary key id;

insert into dataset foo({
        "id": int64("1"),
        "entities": {
                "numbers": []}  ===> You have defined text to be a
closed nullable field.
                                                This instance does not
conform with the type definition.
                                                If text happens to be
null, as per current implementation,
                                                it is *required* to be
defined as null in the record.
        }.
);

insert into dataset foo({
        "id": int64("1"),
        "entities": {
                "text":null,   ====> This would work!

• Removed labels: Severity-MSRBlocker

[GoogleCodeExporter]

It should not be necessary to put fields in with NULL values - leaving them out 
means the same thing - so this is still a valid bug, just not a blocking bug 
since there is a workaround of sorts.

Original comment by dtab...@gmail.com on 30 Jul 2013 at 5:28

[GoogleCodeExporter]

Hmm, okay... That was my thought at first as well: a nullable field need not be 
provided (in which case it will be implicitly given the value NULL).

Why is this invalid now? It seems like a valid issue from what is described here

I guess "Invalid" is not a proper name here, but we don't have 
"Non-reproducible" status

Interesting, I am not able to reproduce it either (on 0.8.6). I wonder what 
commit has fixed this? It looks like it was reproducible at one point

Future request:  Please don't change bugs statuses, particularly to things that 
mean "no future attention", without recording an explanation.  :-)

Interesting side note:  This bug is one point where the AQL religion is 
slightly different than the Couchbase N1QL religion and UCSD SQL++ religion.  
(They would have said "works as designed" to the original bug.)
