JDBC Transaction is not working as expected while using Flow-ref - mule

Question

In mule flow, am unable to run JDBC transactions while using Flow-Ref. The same transactional scope works, if no flow-ref is used.
any ideas ?
Here is my configuration xml.
<mule xmlns:file="http://www.mulesoft.org/schema/mule/file" xmlns:tracking="http://www.mulesoft.org/schema/mule/ee/tracking" xmlns:jbossts="http://www.mulesoft.org/schema/mule/jbossts" xmlns:ee="http://www.mulesoft.org/schema/mule/ee/core" xmlns:jdbc-ee="http://www.mulesoft.org/schema/mule/ee/jdbc" xmlns="http://www.mulesoft.org/schema/mule/core" xmlns:doc="http://www.mulesoft.org/schema/mule/documentation" xmlns:spring="http://www.springframework.org/schema/beans" version="EE-3.4.1" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-current.xsd

Answer 1

Try the following for your flow 2
<flow name="jdbctransactionFlow2"
processingStrategy="synchronous"
doc:name="jdbctransactionFlow2">
The above solution is for the issue mentioned in the post that the Code works in single flow. But not working when tried using flow-ref.
Hope this helps.
