Question on operator ModelGrouper

Hi,
I was wondering about the "scope" of the ModelGrouper, i.e. what exactly will be included into
the model written by the ModelWriter operator (assumed it immediately follows the ModelGrouper).
Will all models from the very beginning of the process chain up to the ModelGrouper be grouped
by this operator?
And what happens when there are some ModelWriters in the chain? Will than the ModelWriter that
follows a ModelGrouper just dump those models into a file that follow a proceeding ModelWriter?

Hi Chris,
the ModelGrouper operator behaves like every operator in RapidMiner: It uses what it recieves. You might make a breakpoint before the ModelGrouper. The result pane will show, which Models are delivered. These are then combined in one single model. The order of the models is determined by the order they are recieved (and hence they are represented in the tab order in the result pane).
These models are then treated as one model, so that all of them are written into a single file, if you use the ModelWriter. They are all restored if you load them again, indepentendly from any operator writing/loading before.
