Comment 1 for bug 1424461

Please note the WF is slightly different. This is another bug. There's a race condition on publishing vars. Whereas the one above failed to execute the join task.

EXPECTED:
{
    "is_done": true,
    "var1": true,
    "var2": true
}

ACTUAL:
{
    "is_done": true,
    "var1": false,
    "var2": true
}

~/st2$ cat ~/tmp/test-complex-join.yaml
version: '2.0'
name: test-complex-join

workflows:

    main:
        type: direct
        output:
            var1: <% $.var1 %>
            var2: <% $.var2 %>
            is_done: <% $.is_done %>
        tasks:

                    var2: false
