Error description

  • To serialize a business object into an IBM Business Process
    Manager (BPM) proprietary XML format, you can use the toXML or
    toXMLString functions on the business object:
    
    var xml = tw.local.variableName.toXML();
    var xmlString = tw.local.variableName.toXMLString();
    
    Alternatively, you can use the serializer API:
    
    var xml = tw.system.serializer.toXml(tw.local.variableName);
    
    To deserialize the XML back into a variable, you use the
    following JavaScript (JS) API:
    
    tw.local.variableName = tw.system.serializer.fromXml(xml);
    
    However, when you run the "tw.local.variableName =
    tw.system.serializer.fromXml(xml)" JavaScript API for an XML
    that contains a serialized object of a business object type, and
    that business object uses a name that is used in multiple
    toolkits, the operation fails and you find an exception like the
    following example in the SystemOut.log file on the server:

Local fix

Problem summary

  • The serialized XML for a business object included only
    information about its type name. During deserialization, IBM BPM
    used the ordered dependency list of the toolkits to find the
    first business object type that had a matching name.
    This business object type might be wrong if the serialized XML
    is of a type from another toolkit that is later in the
    dependency list.
    

Problem conclusion

  • A fix will be included in IBM BPM V8.5.7 cumulative fix 2017.03
    that enhances the serialized XML format with an additional
    attribute that identifies the toolkit or process application
    that contains the business object type so that the
    deserialization can use that information to find the correct
    business object type.
