Using an arraylist to populate output

Anonymous — Tue, 18 Feb 2020 11:18:23 GMT

Hi all, I'm in the following scenario:

Now I can't actually find a way to use my list output and no values are actually printed by tLogRow, though printing values from globalMap and row79 inside the tJavaFlex itself works fine.

I both tried using row79 -- Main -- out and globalMap -- onComponentOk -- tFixedFlowInput -- out.

In the first case I just get blank values in output, in the second case i can pass the arrayList to a value and can't proceed any further to store all values from the list inside columns for a possible output.

Any help much appreciated!

I managed to find a solution:

The missing piece of the puzzle was the tLoop from 0 to ((java.util.List<String>)globalMap.get("key")).size()-1

tFixedFlowInput: ((java.util.List<String>)globalMap.get("key")).get((Integer)globalMap.get("tLoop_1_CURRENT_VALUE"))

For some reason the elaboration is looking pretty slow (only 40rows/s) but at least it works!
