APAR status

• Closed as program error.

Error description

• In some cases selecting value in Coach dependent dropdown
  doesn't lead to change of the value of binded variable, so
  other widgets that are binded to the same var are not updated
  with selected value.
  
  
  This is a bug in the controls/bindings area. The coach
  framework is not sending events when it should be.

Problem summary

• The coach view that has unresolvable data binding remains "dead"
  forever even if the data binding turns to be resolvable later.
  
  USER AFFECTED:
  Business Process Manager Advanced, Standard and Express user who
  has complex object as variable, some coach view binds to the
  property of complex object, the complex object itself may turn
  to null.
  
  PROBLEM DETAILED DESCRIPTION:This is complicated scenario, here
  is an example to describe the details:
  
  -Select control "Child" has "object.object.child" as the value
  of "Selected Item" configuration option.
  -Text control "value" binds to "object.object.child.value".
  -When Select control "Child" receives its new list through Ajax
  service as the result of Selection change in Select control
  "Parent", Select control "Child" sets its selectedItem to null.
  Namely,  the object represented by "object.object.child" becomes
  null.
  -Then, "object.object.child.value" is not resolvable. As the
  result, coach framework isolates Text control "value".
  -When user makes selection in  Select control "Child", the
  object represented by "object.object.child" gets its value.
  However, the isolated Text control (the one binds to
  "object.object.child.value") is never woke up to update itself.
  
  Solution:
  Try to rescue the coach view instances that has a meaningful
  binding string but no binding object (failed to resolve the
  binding previously) when there is a proper chance.
  

Problem conclusion

• The problem is fixed by enhancing 3 javascript files in coach
  framework.
