Cannot create TransactionParams of ConnectionFactory with WLST Offline

Question

Hello dear WL users and geeks,
I'm trying to automate the creation of a weblogic domain using WLST Offline but I've got some problem with the configuration of a JMS ConnectionFactory : I don't know how to activate the XA-Connection factory setting.
Ok, here is the WLST code, results and thoughs are in comments (##) :
==================
## I start with a fresh install of Oracle Weblogic Server 11g R1 (10.3.3) (also tried 10.3.1, same problem) and use the Configuration Wizard to
## create a new Weblogic domain using the default "Basic Weblogic server domain template".
## First, read the domain
readDomain('Oracle/Middleware/user_projects/domains/base_domain/')
## Create a JMSServer
create('MyJMSServer', 'JMSServer')
assign('JMSServer', 'MyJMSServer', 'Server', 'AdminServer')
## Create a JMS Module
create('TestModule', 'JMSSystemResource')
## And now a ConnectionFactory
cd('/JMSSystemResource/TestModule/JmsResource/NO_NAME_0')
fact=create('TestConnFactory', 'ConnectionFactory')
fact.setJNDIName('someJNDIName')
updateDomain()
## Ok, let's see what is defined :
cd ('/JMSSystemResource/TestModule/JmsResource/NO_NAME_0/ConnectionFactory/TestConnFactory')
ls()
## -rw- DefaultTargetingEnabled false
## -rw- JNDIName someJNDIName
## -rw- LocalJNDIName null
## -rw- Name TestConnFactory
## -rw- Notes null
## -rw- SubDeploymentName null
## Uh oh. Why are the 'directories' TransactionParams and SecurityParams missing ? How am I supposed to edit the TransactionParams ?
## Maybe there is a createTransactionParams method ?
dir(fact)
## ['JNDIName', 'class', 'clientParams', 'defaultDeliveryParams', 'defaultTargetingEnabled', 'equals', 'flowControlParams', 'getClass',
## 'getClientParams', 'getDefaultDeliveryParams', 'getFlowControlParams', 'getInvocationHandler', 'getJNDIName', 'getLoadBalancingParams',
## 'getLocalJNDIName', 'getName', 'getNotes', 'getProxyClass', 'getSecurityParams', 'getSubDeploymentName', 'getTransactionParams',
## 'hashCode', 'isDefaultTargetingEnabled', 'isProxyClass', 'isSet', 'loadBalancingParams', 'localJNDIName', 'name', 'newProxyInstance', 'notes',
## 'notify', 'notifyAll', 'securityParams', 'setDefaultTargetingEnabled', 'setJNDIName', 'setLocalJNDIName', 'setName', 'setNotes',
## 'setSubDeploymentName', 'subDeploymentName', 'toString', 'transactionParams', 'unSet', 'wait']
## If I try to invoke any method related to transactionParams, I've got a null pointer exception
==================
Ok, now I'll use the web admin console to edit the transaction parameters : I start the Weblogic Server and go to the web-based Administration console.
In the Domain Structure tree, I go to base_domain > Services > Messaging > JMS Modules.
Then I click on my 'TestModule' module and then on my 'TestConnFactory' Connection Factory.
I go in the 'Transaction' tab and I enable the XAConnectionFactory checkbox.
Finally, I click on the save button.
Let's start a new WLST Offline session and see what's new :
==================
## Read the domain
readDomain('Oracle/Middleware/user_projects/domains/base_domain/')
## Check what is defined in my ConnectionFactory
cd ('/JMSSystemResource/TestModule/JmsResource/NO_NAME_0/ConnectionFactory/TestConnFactory')
ls()
## Hey look, the TransactionParams appeared :
## drw- TransactionParams
## -rw- DefaultTargetingEnabled true
## -rw- JNDIName someJNDIName
## -rw- LocalJNDIName null
## -rw- Name TestConnFactory
## -rw- Notes null
## -rw- SubDeploymentName null
## Go in there :
cd('TransactionParams/NO_NAME_0')
ls()
## -rw- TransactionTimeout 3600
## -rw- XAConnectionFactoryEnabled                    true
==================
So :
- Why the TransactionParams setting is not directly created or available when a new ConnectionFactory is created ?
- How can I create a JMS ConnectionFactory and edit its TransactionParams using only WLST Offline (i.e., without the admin console and without WSLT online) ?
Any help appreciated,
Thanks !

Ok, I found a solution :
=============
cd ('/JMSSystemResource/TestModule/JmsResource/NO_NAME_0/ConnectionFactory/TestConnFactory')
create('DUMMY', 'TransactionParams')
ls('TransactionParams/NO_NAME_0')
## -rw- TransactionTimeout 0
## -rw- XAConnectionFactoryEnabled false
=============
But it seems strange to have to create a dummy TransactionParams. Is it the correct way to do it ?
