Visualizing Interactions Not In Root ModuleDefinition

[nroehner]

Given a ModuleDefinition with a sub-Module that contains a genetic production Interaction between a CDS and a protein and a FunctionalComponent for a transcriptional unit (TU) that contains the CDS (see tu_production_with_sub_intxn.zip), I would expect VisBOL to visualize the components of the TU along a backbone with a production arrow pointing from the CDS to the protein. Currently, however, only the TU components along a backbone are visualized - the production interaction is omitted.

The only way that I seem to be able to visualize a production interaction as desired is by adding a second genetic production Interaction between FunctionalComponents for the CDS and protein to the root ModuleDefinition (see tu_production_with_root_intxn.zip). I would prefer to not have to do this since the second production Interaction is redundant information that might be difficult for other software tools to merge with the first production Interaction.
