Test source

Running the attached program results in this output, even though according to the docs everything should be fine:

** (process:9352): DEBUG: test-json-set.vala:19: { "member" : "foo" }

(process:9352): Json-CRITICAL **: json_node_get_node_type: assertion `node != NULL' failed
** (process:9352): DEBUG: test-json-set.vala:22: { "\xa8\xae.\xca\u0001\u007f" : null }
Comment 1 Emmanuele Bassi (:ebassi) 2011-02-15 15:56:52 UTC 
an odd result is that if I change the g_debug() to:

  json_object_set_string_member (obj, "member", "foo");
  g_assert (strcmp (json_object_get_string_member (obj, "member"), "foo") == 0);

  json_object_set_string_member (obj, "member", "bar");
  g_assert (strcmp (json_object_get_string_member (obj, "member"), "bar") == 0);

the test passes without triggering any assertion. so it looks like it's not a problem of JsonObject or JsonNode, but a problem somewhere in JsonGenerator.

This problem has been fixed in our software repository. The fix will go into the next software release. Thank you for your bug report.
