But adding a second pair of curly brackets results in initializing all vectors with one element set to its default value (e.g. `msg->bool_values={{}}` will result in `{false}`)\r\nIt seems that `{{` is needed only when you want to initialize a vector with more than one element.\r\n\r\nThis would PR allows to get back to what I think was the expected behavior.\r\n\r\nPending CI jobs to confirm that no new warnings show up:\r\n * Linux [![Build Status](http://ci.ros2.org/job/ci_linux/1377/badge/icon)](http://ci.ros2.org/job/ci_linux/1377)\r\n * OSX [![Build Status](http://ci.ros2.org/job/ci_osx/1073/badge/icon)](http://ci.ros2.org/job/ci_osx/1073/)\r\n * Windows [![Build Status](http://ci.ros2.org/job/ci_windows/1382/badge/icon)](http://ci.ros2.org/job/ci_windows/1382)"},"comment":{"url":"https://api.github.com/repos/ros2/system_tests/issues/comments/223329836","html_url":"https://github.com/ros2/system_tests/pull/128#issuecomment-223329836","issue_url":"https://api.github.com/repos/ros2/system_tests/issues/128","id":223329836,"user":{"login":"dirk-thomas","id":1335366,"avatar_url":"https://avatars.githubusercontent.com/u/1335366?v=3","gravatar_id":"","url":"https://api.github.com/users/dirk-thomas","html_url":"https://github.com/dirk-thomas","followers_url":"https://api.github.com/users/dirk-thomas/followers","following_url":"https://api.github.com/users/dirk-thomas/following{/other_user}","gists_url":"https://api.github.com/users/dirk-thomas/gists{/gist_id}","starred_url":"https://api.github.com/users/dirk-thomas/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/dirk-thomas/subscriptions","organizations_url":"https://api.github.com/users/dirk-thomas/orgs","repos_url":"https://api.github.com/users/dirk-thomas/repos","events_url":"https://api.github.com/users/dirk-thomas/events{/privacy}","received_events_url":"https://api.github.com/users/dirk-thomas/received_events","type":"User","site_admin":false},"created_at":"2016-06-02T15:34:37Z","updated_at":"2016-06-02T15:34:37Z","body":"LGTM"}}
