  • Closed as program error.

Error description

  • When you have a client-side human service (CSHS) that has a date
    variable. Clicking any button that takes you away from the CSHS
    and calls an IBM Business Process Manager (BPM) service fails
    and you see the following CWTBG0019E Java date format error even
    if the service does not do anything with the date:
    
    "Unexpected exception during execution. Exception information:
    ''0''. During execution of the API an unexpected exception
    occurred."
    
    The CSHS works fine if you run it as a stand-alone service but
    fails if you run it in the context of a business process
    definition (BPD).

Local fix

Problem summary

  • If a CSHS used as a task has a date variable and the sequence
    flow heading into a service call has save enabled, the service
    call fails with an error. The service does not use the Date
    variable. However, the Date variable must have a value so that
    it can be saved in the execution context.
    
    Code retrieves the data after the CSHS is saved to update the
    inputs to the service. It expects each of the values to either
    be a TWObject or a Java primitive. For date variables the value
    is neither, as shown in the error message.
    

Problem conclusion

  • A fix will be included in IBM BPM V8.5.7 cumulative fix 2016.12
    that allows navigation away from CSHS containing a date
    variable.
    
    To determine whether the cumulative fix is available and
    download it if it is, complete the following steps on Fix
    Central:
    
    1. On the Select product tab, select WebSphere as the product
    group, IBM Business Process Manager with your edition from the
    WebSphere options, All as the installed version, and All as the
    platform, and then click Continue.
    2. In the Text field, enter "cumulative fix", and click
    Continue.
