Error description

• User has defined an input field to be a drop-down (data entry)
  widget.  There are 2 list items defined for the drop-down
  widget, but neither of these items are shown as the default
  selection in the drop-down widget.  If the same definitions are
  done on a Web project versus RCP then the first item in the
  list is used as the default selection.

  ****************************************************************
  The code, SWTElementFactory.java, that creates the drop down
  options first creates an empty/blank option.  After the user
  defined options are added the code then goes through a loop to
  try and match the value from the input field with one of the
  options in the list.  If the user specifies an option that is
  blank it will not get matched because the initial blank option
  that is added always matches first.
  

Problem conclusion

• The problem was fixed in SWTElementFactory.java by preventing
  the blank option that HATS automatically generates from being
  matched first and it will only be used if none of the other
  options in the list match.  The for loop for matching the
  options to the host value will start at index 1, instead of 0,
  if there are more than 2 options in the list.  Thus, the first
  HATS generated blank option will be ignored.  If no match is
  found then the drop-down list will default to the HATS
  generated blank option.
