AMX-BPM: Getting error while creating caseobject from Business process

[Shrijeet Sinha]

Hi

I am getting below error when i am trying to create caseobject from business process.

cause: javax.script.ScriptException: com.tibco.n2.javascript.EcmaError: TypeError: Cannot set property "firstName" of null to "SHRIJEET"

 

Well i know it is because class is not getting instatntiated but i am definitely instantiating it and it works for normal attribute.

Error is coming for attribute which is of BPM type of another "Global" class.

Attached is my CaseDataModel and Process pacakge.

Summary:

========

1) BDS Project

a) CaseClass created with name :orderDetails

b)Gobal Class also there with name:CustomerDetails

c) One attribute is caseclass isCustomerDetailsSection which is of type global class ,CustomerDetails.

Exactly on step where i am setting value ofCustomerDetailsSection attributes, i am getting error.

 

2) Process

Business Service - To take values from user task

Business process: Script task - To assign values taken in user task to local datafield objects. and then call service task.

 

SCript :

//Instantiated class

OrderDetails=com_example_casedatabom_Factory.createorderDetails();

CustomerDetails=com_example_casedatabom_Factory.createCustomerDetails();

//Mapping values which was passed from pageflow

OrderDetails.orderId=OrderDetailsParameter.orderId;

OrderDetails.orderState=OrderDetailsParameter.orderState;

CustomerDetails.firstName=OrderDetailsParameter.customerDetailsSection.firstName;

Log.write(CustomerDetails.firstName);

CustomerDetails.lastName=OrderDetailsParameter.customerDetailsSection.lastName;

Log.write(CustomerDetails.lastName);

CustomerDetails.contactDetails=OrderDetailsParameter.customerDetailsSection.contactDetails;

Log.write(CustomerDetails.contactDetails);

CustomerDetails.address=OrderDetailsParameter.customerDetailsSection.address;

Log.write(CustomerDetails.address);

CustomerDetails.landmark=OrderDetailsParameter.customerDetailsSection.landmark;

Log.write(CustomerDetails.landmark);

//Getting all values correct till above

 

//Issue starts from here when i am mapping value CustomerDetailsSection Attribute of caseclass which is of type GlobalClass

//ERROR I get everytime : javax.script.ScriptException: com.tibco.n2.javascript.EcmaError: TypeError: Cannot set property "firstName" of null to "SHRIJEET"

OrderDetails.customerDetailsSection.firstName=CustomerDetails.firstName;

OrderDetails.customerDetailsSection.lastName=CustomerDetails.lastName;

OrderDetails.customerDetailsSection.contactDetails=CustomerDetails.contactDetails;

OrderDetails.customerDetailsSection.address=CustomerDetails.address;

OrderDetails.customerDetailsSection.landmark=CustomerDetails.landmark;

 

Other "normal" attributes of same caseclass is fine.

Seems WHen global class is referenced in attribute of caseclass , that is just not getting instantiated.

Please can i have advise how to proceed in this situation.

Hi Shrijeet,

Can you please see if adding the following line

OrderDetails.customerDetailsSection = com_example_casedatabom_Factory.createCustomerDetails();

before

OrderDetails.customerDetailsSection.firstName=CustomerDetails.firstName;

resolves the issue

'customerDetailsSection' object does not seem to be getting instantiated in the script which probably explains the error message 'Cannot set property "firstName" of null to "SHRIJEET"'

Thanks,

Joshy

Hi, Shrijeet.

Instead of assigning values to the customerDetailsSection individually, you can do this:

 

OrderDetails.customerDetailsSection=CustomerDetails;

 

I've tested it and it works.

Thanks,

Ketaki.
