I think I'm not implementing msg.complete correctly.
Here is the join node:
So I want the first parameter followed by "a" then the second parameter followed by "b" and last a string of numbers, such as "1,1,2,2,1,2\n".
For example, "4a1b1,1,2\n".
Initially, I tried using the count (after a number of message parts). But the resulting string needs to follow the order parameter1, a, parameter2, b, numberSequence. The order could be easily rearranged if using count. That's why I think I need to use msg.complete.
