Loop Repository doesn't loop example sets in the right order..

hi,

does the loop repository operator take the Example sets in the right order as listed in the repository (e.g alphabetically?)

somehow, I got the feeling it does not join the correct example sets...

 

I originally wanted to join 2 c orresponding lists, and there are about 10 pairs of lists in 2 repositories, but it seems they dont take the lists one-on-one in the right repository order, is that correct?

 anyone?

 

I was just wondering, because at some time, the third list or so, items cannot be joined by key column anymore, there are no matching fields, which is weird, as they do match in the lists.. therefore I am assuming that Rapidminer is not taking the items in the right repository order, is that correct?

    There's a lot of looping going on in your process and it's hard for me to understand without some data. Are those data sets available to share?
