Robbie Gemmell updated PROTON-1831:
-----------------------------------
       Reporter: Alan Conway  (was: Kim van der Riet)
    Description: See PROTON-1832 for the detail, this JIRA was inadvertently spammed with
comments for it.  (was: When using nested complex types (for example, a list of maps or an
array of lists), the compiler fails to compile. For example, the following code snippet (saved
as {{ctt.cpp}}):
{noformat}
#include <map>
#include <vector>
#include <proton/types.hpp>

int main(int, char**) {
    std::map<proton::value, proton::value> m1 = {{uint8_t(0), "zero"}, {uint8_t(1),
"one"}};
    std::map<proton::value, proton::value> m2 = {{true, "true"}, {false, "false"}};
    std::vector<std::map<proton::value, proton::value> > am = {m1, m2};
    proton::value pv = am;
}{noformat}
fails compilation with the following error:
{noformat}
