A SubmittedValueEntry record is the unit of a cached request transaction - a primitive operation on the bean container required by a request, which is either the reading, writing, or "unlinking" of a bean value, or execution of a no-arg method. The pure data members (sans comments - see code link above for full details) are as follows:

public class SubmittedValueEntry {
  public String valuebinding;
  public String componentid;
  public Object oldvalue;
  public Object newvalue;
  public boolean isEL;
  public boolean isdeletion = false;
  public String reshaperbinding;
}

This structure is to be interpreted as a kind of "union" in which some entries are expected to be null where not relevant.

More details are in the section on the RequestSubmittedValueCache.
