hi kukeltje,
very appreciate your replies!
I'm a new one here. And I even don't know JIRA... What a pity!
I go through the topic you have metioned
http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4238433#4238433
If I don't misunderstand that post, changing org.hibernate.dialect can get my problem solved?
However, my org.hibernate.dialect is configured as org.hibernate.dialect.MySQLInnoDBDialect...
<property name="hibernate.dialect">org.hibernate.dialect.MySQLInnoDBDialect</property>
| <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
| <property name="hibernate.connection.url">jdbc:mysql://localhost:3306/jbpm4db</property>
| <property name="hibernate.connection.username">root</property>
| <property name="hibernate.connection.password">123456</property>
| <property name="hibernate.hbm2ddl.auto">update</property>
| <property name="hibernate.show.sql">true</property>
|
| <mapping resource="jbpm.repository.hbm.xml" />
| <mapping resource="jbpm.execution.hbm.xml" />
| <mapping resource="jbpm.history.hbm.xml" />
| <mapping resource="jbpm.task.hbm.xml" />
| <mapping resource="jbpm.jpdl.hbm.xml" />
| <mapping resource="jbpm.identity.hbm.xml" />
So I think my problem is different from that. ?
And the ConstraintViolationException
here is because `FK_EXEC_SUPEREXEC` but not `FK_EXEC_INSTANCE` (Yes, it's due to that I use sub-process. Because if I put these 2 fork flows into One process, one embedded into another, tasks in Inner-Fork-Flow will be created twice)
This time I try to be clever to USE SOME KIND OF SEARCH FUNCTIONALITY (I was stupid enough yesterday~~). I learn Google! hahaha
Fortunately, I find this issue list
https://jira.jboss.org/jira/secure/BrowseVersion.jspa?id=10052&versionId=12313199&showOpenIssuesOnly=true (And I know JIRA! Fortunately again)
And I find this issue JBPM-2303 UNRESOLVED Exception with a process containing a fork/join
You can touch it:https://jira.jboss.org/jira/browse/JBPM-2303
I ran that tests and got exceptions. I think join/fork flow has its own bugs.
I should go to see what happens in jBPM4. I should have enough time to do that. It's my fault.
I really want to know what's wrong with my code, What is the actual reason caused that exception happens. If it is proved to be a bug, I can sleep well tonight~~ hahaha
Please help me again. Thx!
Or I have to wait for jBPM4 released? hahahaha
