Error description

  • When you migrate instances from one snapshot to a newer one,
    instances might fail to migrate to the new snapshot. In an FFDC
    log, you see an error similar to this error:
    
    Caused by: com.lombardisoftware.core.TeamWorksRuntimeException:
    Attempt to access TWObject with classId
    TWClass.ab704972-f8ab-4233-a192-23836c181300 that is not

Local fix

Problem summary

  • When you migrate instances to a new snapshot, new variables that
    you added with a default value are automatically initialized.
    While going through the values that are set in the business
    process definition (BPD) instance, IBM BPM tries to look up the
    business object definition in the new snapshot where the
    variable was removed, causing the error.
    

Problem conclusion

  • A fix will be included in an IBM BPM V8.5.6.0 cumulative fix
    that ensures variables that were deleted are ignored.
    

Temporary fix

  • Not applicable
