IV07141: BPEL ASSIGN ACTIVITY ASSIGNS DEFAULT VALUES

WebSphere Process Server V7.0.0 Fix Pack 5 (V7.0.0.5)

APAR status

• Closed as program error.

Error description

• In case of the XML Schema base types xs:int, xs:boolean, and
  xs:double
  the BPEL Assign activity currently assigns a default value (0 in
  case of
  xs:int, false in case of xs:boolean, and 0.0 in case of
  xs:double) to
  the target element if the source element is not set. For all
  other XML
  Schema base types, the BPEL Assign activity assigns the value
  "null" to
  the target element, if the source element is not set.
  This behavior is wrong. Instead, no default values should be
  assigned
  by the BPEL Assign activity and elements, that are not set in
  the
  source data structure should remain not set in the target data
  structure.

Problem summary

• If an XPath query is used inside a BPEL process to evaluate a BO
  property of XML Schema simple
  type xs:boolean, xs:byte, xs:double, xs:float, xs:int, xs:long,
  xs:short, xs:unsignedByte,
  xs:unsignedInt, or xs:unsignedShort and the property is not set,
  it appears that the
  corresponding default value (false for xs:boolean, 0.0 for
  xs:double or xs:float,
  and 0 for the others) is returned. In case of a BPEL assign
  activity this results in the
  property of the target BO being set to a default value if the
  property in the the source BO
  is not set. With this fix, the XPath query does not return a
  default value.
  
  This fix needs to be enabled via a custom property. To set this
  custom property, connect to the
  administrative console and navigate to the appropriate Java
  virtual machine custom properties page:
  
  Servers > Application servers > server_name, and then, in the
  Server Infrastructure section,
  click Java and process management > Process definition > Java
  virtual machine > Custom Properties
  
  Add the following custom property:
  
  Name:  XPathExpressionEvaluation
  Value: disableDefaultValues
  
  Please note that the server needs to be restarted for the
  property to become active.
  
  
  Note: It is strongly recommended to install ESB APAR IC79110 in
  addition because otherwise this fix
        may not become effective.
