PM32844: focus loops between EGL Dojo comboboxes

APAR status

• Closed as program error.

Error description

• Environment:
  
   - Product name (Build ID or version/patch level): IBM Rational
  Business Developer version 8.0.1
  Reproducible Y/N: Y
  
  Description of problem:
  
  When a RUI handler is tested in Microsoft Internet Explore
  version 8, focus might loop between comboboxes.
  
  Problem could be reproduced frequently on Microsoft Internet
  Explorer version 8.0.6001.18702 and exceptionally on FireFox
  3.6.13 and not in the Rational Business Developer preview of the
  Rich UI Editor.
  
  Steps to reproduce:
  
  1) Create a Rich UI handler like
  handler TestCombo type RUIhandler {initialUI = [ ui
  ],onConstructionFunction = start, cssFile='css/TestCombo .css',
  title='TestCombo'}
  
   ui GridLayout{ columns = 3, rows = 4, cellPadding = 4, children
  = [ ComboBox4, ComboBox3, ComboBox2, ComboBox1 ] };
   ComboBox1 DojoComboBox{ layoutData = new GridLayoutData{ row =
  1, column = 2 }, values = ['value1','value2','value3'], value =
  'value2' };
   ComboBox2 DojoComboBox{ layoutData = new GridLayoutData{ row =
  2, column = 2 }, values = ['value1','value2','value3'], value =
  'value2' };
   ComboBox3 DojoComboBox{ layoutData = new GridLayoutData{ row =
  3, column = 2 }, values = ['value1','value2','value3'], value =
  'value2' };
   ComboBox4 DojoComboBox{ layoutData = new GridLayoutData{ row =
  4, column = 2 }, values = ['value1','value2','value3'], value =
  'value2' };
  
   function start()
   end
  end
  
  2) Open TestCombo in Rich UI editor
  3) open preview tab and click on the icon 'show the web page in
  an external browser'
  4) when the page is opened in Microsoft Internet Explorer v8:
  click as fast as possible in the comboboxes with the mouse:
  - click in combo1 then combo2 then combo3 then 4 and repeat it
  as fast as possible
  5) after maybe 10 clicks, the focus starts to loop between the
  comboboxes and clicking on the arrow doesn't display the
  dropdown list anymore: comboboxes are unusable.
  
  
  Workaround:
  The problem hasn't been reported with EGL comboBox
  (com.ibm.egl.rui.widgets.Combo)
