There's definitely something wrong with the capx.
The event sheet showed 0 events like Ubivis reported, but the preview is still logging messages to the console like you said.
At first I thought it was some kind of hard-wired behavior, but after some time adding events (in the previously empty event sheet) a lot of events popped out of nowhere.
I guess the capx is corrupted somehow.
Also the action to set the learning rate and momentum factor is wrongly named as a duplicated "Define hidden node count".
I would like to suggest an action to define/add inputs in the same way as inputs are set, so they could be dynamically defined through expressions. This would allow to run a loop to define all inputs, which would be extremely useful when using an array as input for a feature detection NN for instance. Something in the line of:
Define new input str( loopindex("x")&loopindex("y") )[/code:1jmtvu2q]
Currently it's impractical to define all inputs manually through the "Add parameter" button, since a small 10x5 array would need 50 inputs to be defined by hand.
