So there is no way of iterating throught list with values put vertically in a column ? But doesn't your solution gives me just if element in iteration is in some group of values let's say (1,2,3)? Le't say i have a list of 2 SubParamAttribute. One having value==1, and another value==2.I wan't my list to iterate in the first column and when value 1 in cell is equal to value==1 from SubParamAttribute to catch in column one that SubParamAttribute with has value=1, so I can send that SubParamAttribute to the next column because my SubParamAttribute has another list of other values to iterate ? Is it possible ? -- View this message in context: http://n3.nabble.com/Decision-table-list-problem-tp214823p216823.html Sent from the Drools - User mailing list archive at Nabble.com.
