    Spoon/Kitchen throws exceptions if a transformation (Outer) has a mapping to second transformation (Between) which itself has a mapping to a third transformation (Inner). Will attach simple test case to reproduce it. Note: - Running Between using a DataGrid as input instead of the Mapping Input step works fine (i.e. the single level of nesting (mapping) from Between to Inner works fine on its own). - Circumventing the mapping in Between to Inner by disabling the hops around the mapping-step and "short-circuiting" past it runs fine from Outer (i.e. the single level of nesting (mapping) from Outer to Between works fine on its own). Also: I tried various combinations of - explicitly defining fields in the Mapping Inputs, or letting it implicitly pass through all unspecified fields, - explicitly connecting the input and output steps in the Mapping-step, or letting it figure it out on its own. The specific exceptions actually vary depending on how the transformation is initiated: - Previewing Outer by selecting its Sort rows step reports: {code} 2012/04/26 17:37:06 - Mapping to Between.0 - ERROR (version 4.2.0-stable, build 15748 from 2011-09-08 13.11.42 by buildguy) : Unable to load the mapping transformation because of an error : org.pentaho.di.core.exception.KettleException: 2012/04/26 17:37:06 - Mapping to Between.0 - ERROR (version 4.2.0-stable, build 15748 from 2011-09-08 13.11.42 by buildguy) : Unable to prepare (allocate, initialize) the execution of the mapping (sub-transformation) 2012/04/26 17:37:06 - Mapping to Between.0 - ERROR (version 4.2.0-stable, build 15748 from 2011-09-08 13.11.42 by buildguy) : 2012/04/26 17:37:06 - Mapping to Between.0 - ERROR (version 4.2.0-stable, build 15748 from 2011-09-08 13.11.42 by buildguy) : We failed to initialize at least one step.
