Apologies Ronald, I was hoping for more of a discussion as opposed to a solution to my
specific problem.
Here's the fork and join from my workflow.
| <java class="org.workflow.FindProviders" g="276,7,80,40"
method="execute" name="find providers">
| <transition name="" to="fork"/>
| </java>
|
| <fork g="298,85,80,40" name="fork">
| <transition g="-62,-18" name="validate red"
to="validate red request"/>
| <transition g="-64,-18" name="validate exp"
to="validate exp request"/>
| <transition g="-63,-17" name="validate sys"
to="validate sys request"/>
| </fork>
|
| <custom continue="async" name="validate red request"
class="org.workflow.Validate1" exp="#{myFirstObj}">
| <transition g="-27,-18" name="" to="join"/>
| </custom>
|
| <custom continue="async" name="validate exp request"
class="org.workflow.Validate2" exp="#{mySecondObj}">
| <transition g="-27,-18" name="" to="join"/>
| </custom>
|
| <custom continue="async" name="validate sys request"
class="org.workflow.Validate3" exp="#{myThirdObj}">
| <transition g="-27,-18" name="" to="join"/>
| </custom>
|
| <join g="267,368,80,40" name="join">
| <transition name="check results" to="evaluate validation
results" g="-47,-16"/>
| </join>
| ...

Starting the process using JobExecutor config
<jbpm-configuration>
|
| <process-engine-context>
|
| <job-executor threads="5" idle="10" idle-max="0"
lock-millis="0" />
|
| </process-engine-context>
|
| </jbpm-configuration>
Using MySQL and everytime I run the forks run concurrently as expected. But then sometimes
in between the forks or sometimes after I get this exception
| org.hibernate.StaleObjectStateException: Row was updated or deleted by another
transaction (or unsaved-value mapping was incorrect):

I read somewhere this is expected behaviour but this surely can't be right... can it?
