> Deserialization of nested list discards content
> -----------------------------------------------
>
> Key: THRIFT-4436
> URL: https://issues.apache.org/jira/browse/THRIFT-4436
> Project: Thrift
> Issue Type: Bug
> Components: JavaScript - Library
> Affects Versions: 0.10.0, 0.11.0
> Reporter: Philip Frank
>
> I'm trying to transmit a list of lists, like this:
> {code}
> service HelloSvc {
> list<list<string>> test()
> }
> {code}
> Using XHR Transport and JSON Protocol, with a service implementation in
> Python like this:
> {code}
> class HelloSvcHandler:
> def __init__(self):
> pass
> def test(self,):
> return [
> ["s1", "s2"],
> ["s3", "s4"],
> ["s5"]
> ]
> {code}
> The serialized response looks good to me (seen in browser development tools):
> {code}
> [1,"test",2,0,{"0":{"lst":["lst",3,["str",2,"s1","s2"],["str",2,"s3","s4"],["str",1,"s5"]]}}]
> {code}
> However, when deserialized to JavaScript, the result looks like this:
> {code}
> [["s1","s2"],[],[]]
> {code}
> I would expect it to look like this:
> {code}
> [["s1","s2"],["s3","s4"],["s5"]]
> {code}
> It looks to me like during JSON deserialization, all but the first entry in
> the list of lists lose their content.
