APAR status

• Closed as program error.

Error description

• When a user types into an input field and that field is full the
  cursor is automatically moved to the next input field due to the
  auto advance feature in HATS.  However, when this happens in the
  customer's 5250 application the next input field available is
  rendered as a drop down in HATS.  When the drop down gets focus
  and the users presses the enter key to submit the page the wrong
  value is being set for the input field being rendered as the
  drop down.  As a result the host application is going to the
  wrong screen and the users do not see the expected data.
  
  This problem only seems to occur when the input is rendered as a
  drop down.  If its rendered as a standard text input the problem
  does not occur and the correct value is sent to the host.
  

Local fix

• The customer was able to get around the problem by disabling the
  auto advance feature in this transformation.

  * USERS AFFECTED: HATS users rendering special 5250 input      *

  *                      "Numeric data plus numeric specials"    *
  *                      is rendered as a drop down,  the text   *

  * RECOMMENDATION:                                              *
  ****************************************************************
  The CARETPOS variable in the JavScript is not being set to the
  correct location when a drop down widget is used for a 5250
  input field of type of type "Numeric data plus numeric
  specials".  As a result, when the page is submitted the data
  could be cut off and cause the wrong value to be sent to the
  host.
  

Problem conclusion

• The compareAgainstOriginal method in lxgwfunctions.js file was
  modified to set the CARETPOS to the correct location which is
  the PS position to the right of the last charater entered in
  the input field.  This method was already determining the
  cursor location to set so the code was modified to check and
  see if the input element is a drop down.  If it is the
  CARETPOS will be set to the correct location.
