Process Composer for Dashboard displays the parameters in the
simulation process or simulation activity.
If there is an error in the parameter file, such as invalid XML,
the file will not be imported from the working directory. To allow you to
determine the problem with the parameter file,
Process Composer for Dashboard does not clean up the working
directory if the import fails. Similarly, the parameter file will not be
imported from the working directory if it contains an expression in the result
element. Error messages describing the illegal expression are written to the
execution log.
