"[Solved] Combining collection after windowing"

Dear all,

Being quite optimistic after my last problem has been solved I started to expand my process facing another setback when discovering new problems of which I think that they are kind of bugs:
Missing id attribute after Windowing operator http://rapid-i.com/rapidforum/index.php/topic,5214.0.html
Error in Generate Attributes operator http://rapid-i.com/rapidforum/index.php/topic,5213.0.html

Anyway, I hope that there's anyone out there who might be able to help with a workaround. As a result of the process I would like to have a single table with one ID attribute and all the prediction attributes created by windowing in each loop.


I have attached the code I tried to use with the shortcomings in the "generate attributes" and "select attributes" operator mentioned before.
