I think there's a bug in ModelApplier which causes the wrong ID to appear in certain rows.
Attached are 2 screenshots: one shows the dataset before ModelApplier (breakpoint) and another after ModelApplier.
Notice how the ID for Row 868 is the wrong one (identical to Row 866) ?
Looks like a bug to me but I'm a RapidMiner newbie so maybe I'm doing something wrong.
Maybe this is related, I get for the ExampleSet: "ExampleSource (2): The ID attribute 'item_id' is defined with a nominal value type but the possible values are not defined ..."
This is strange because I defined 'item_id' as string and not nominal:
name = "item_id"
sourcecol = "1"
valuetype = "string"/>
Please advise, thanks.
