Philip Frank commented on THRIFT-3669:
--------------------------------------

Possibly fixed as THRIFT-4436 for 0.12?

> JS Deserialization of lists of lists is broken

>                 URL: https://issues.apache.org/jira/browse/THRIFT-3669
>             Project: Thrift
>          Issue Type: Bug
>          Components: JavaScript - Library
>    Affects Versions: 0.9.3
>            Reporter: Christian B├╝rckert
>            Priority: Major
>         Attachments: 0001-Fixed-THRIFT-3669.patch, THRIFT-3669-0.10.0.pach, 
> thrift.js
>
>
> struct QueryResult {
>       1: required list<list<string>> rows;
> }
> service QueryService{
>       QueryResult query(); 
> }
> Using TJSONProtocol the list<list<string>> is transmitted correctly but 
> deserialized wrong. Only the first sublist will contain the correct string 
> values the second, third and so on will be empty. The error is a combination 
> of readListBegin, readListEnd and readString (in thrift.js) which somehow 
> interacts wrongly with the internal rstack when lists are included in lists. 
> As a temporary solution until the deserialization is fixed I advice others to 
> create an intermediate struct which contains the sublists.
