[SOLVED] RapidMiner Self-Organizing Map "number of dimensions" is mandatory?

The SOM operator provided in RapidMiner "core" seems to require me to specify the number of attributes of the resultant ExampleSet. Is this analogous to the number of clusters as in the usual terminology of SOMs? Doesn't this go against the principle of the algorithm? It's an unsupervised process, meaning it's data-driven, and arrives at a suitable number of clusters depending on the data?
