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}
