Attribute List Incorrect after Split
After using the SPLIT node in RapidMiner, the attribute list in all subsequent nodes is incorrect - all the new split attributes are not names correctly and cannot be selected. For example, if you place a SELECT ATTRIBUTES node after a SPLIT node (having selected unordered attributes in the split node), then select SUBSET in the SELECT ATTRIBUTES node, all the new split attributes will be incorrect. I even tried using regular expressions to capture the new attributes without luck. Does anyone have any suggestions?

One small addition for correctness: actually it is not really a bug, but since the output attributes of the split operator depend on the actual data (i.e. values of the examples) and not just on the meta data (i.e. attribute names and types etc.), it can't know which attributes it will output before it has actually been executed.

you've found a bug in the Split operator (that's how we call "nodes"
