discretize fail

I am getting the following error when using a Discretize node before an IOMultiplier node:

Hello mcavaret

We cannot reproduce the error this way. Please post the complete process (copy the text from the xml-tab) and / or reproduce the error using data from one of the datagenerator - nodes (IO->Generator).
