KRACOEUS-7431 added fields

The Jira requested more fields be added to the Medusa page, this tries to do that.  I tried to add proposal personnel information into the proposal medusa section without success.  Notice Proposal-MedusaSection-PropDevProposalPersonsSummary.  I have tried a number of iterations to get it to work, without success.  When I un-comment the part where I add it to Proposal-MedusaSection-PropDevSummary I get the following error.  Any ideas on how to do it?

java.lang.ClassCastException: org.kuali.rice.krad.uif.container.NodePrototype cannot be cast to org.kuali.rice.krad.uif.component.Ordered
at org.kuali.rice.krad.uif.util.ComponentUtils.sort(ComponentUtils.java:839)
at org.kuali.rice.krad.uif.container.ContainerBase.sortItems(ContainerBase.java:190)


The code as is works, and does NOT display personnel information.
I agree with @chrisdenne. thanks for the documentation though.
