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.
