Error description

• On fields that are defined as DDS fields with Right Adjust with
  Blanks (RB), Right Adjust with Zeros (RZ) or Field Exit Required
  (FER) the emulatefieldexit is not working as it should.
  For example:
  There is a numeric field with 5 digits and
  CHECK(RB) attribute.
  
  1. The field has preset value below
   00022
  2. if I update the third digit by '1'
   00122
  3. Press Enter with the caret on the field
   00012
  It should be
     001
  
  Another pattern
  1. The field has preset value below
   00022
  2. if I update the first digit by '1'
   10022
  3. Press Enter with the caret on the field
   01002
  It should be
       1
  

Local fix

• Disable emulatefieldexit, or hit the field exit key on these
  fields.

  ****************************************************************
  The actual cursor position was not being used in HostScreen.java
  
  when sending an emulated field exit.  Instead the cursor was
  set to the end of the field data.
  

Problem conclusion

• HostScreen.java was changed so that when emulating a field exit
  
  the cursor position that is used is the position of the cursor
  on the transformation when the the screen is submitted.
