You can't have a tasklet in your step *and* a parent that is a PartitionStep. Look at the samples for an example of how to set it up (make sur ethe Batch version of the sample matches what you are using because the XML configuration of partitioning changed in trunk recently).

This actually solved the problem and made me see other wrong configurations in this file

thanks, dave
