Can't merge flow variable stacks! Likely a loop problem.


Please help me!
I got an error showing that “Can’t merge flow variable stacks!” as in attached pic.
I use “Table Row to Variable” and “Cross Joiner” to get the info from input file in two different reader nodes for different files.
Later, rows from second flow are split using “Reference Row Splitter” with those from first flow.
There the problem starts!

Oops, luckily, I found that “Loop End” is required for every “Loop Start” and the problem is gone! :smiley:
