I was trying to do something very simple. I wanted one of the conditions in my workflow to be a logical and of a couple of things. When I put this in, the workflow seemed to abort, but I can't tell why. Does anything look wrong with the following? And if not, does anyone have any suggestions on the best way to turn on logging to find the problem?
<decision name="useX">
<transition name="IsXAllocated" to="IsXAllocated">
<condition>#{(true==true) && (false==false)}</condition>
</transition>
<transition to="BuildResponse" name="BuildResponse"></transition>
</decision>
Thanks

Hey Thanks for sending me on the right path, just had to do a little more research and learned a bit more of how everything its connected on the back
Indeed it was the org.hibernate.dialect.PostgreSQLDialect I was using the default, but even modifying, the property I was getting the exception
after reading a bit more i decided to mod the whole persistence.xml file and looked for some examples at google and founded this
> http://stackoverflow.com/questions/1061091/persistence-xml-and-osgi-equinox
i know its not for jboss seam but it does contain info of how the persistence.xml should be
here is the result:

When starting up JBPM using Configuration.buildProcessEngine() I get an exception
org.jbpm.api.JbpmException: no jBPM DB schema: no JBPM4_EXECUTION table. Run the create.jbpm.schema target first in the install tool.
at org.jbpm.pvm.internal.cmd.CheckDbCmd.execute(CheckDbCmd.java:50)
I put a breakpoint at CheckDbCmd at that line and found out that there is an underlying exception:
org.hibernate.HibernateException: createQuery is not valid without active transaction
However transactions are definitely enabled (Spring transactions, see stacktrace below). I've also tried a multitude of variations of configuring transaction management in jbpm, such as <hibernate-session current="true" /> and changing current to false and lots of other variations.I somehow have the impression it could be related to Tom Baeyens http://community.jboss.org/thread/145924.
Has anyone any idea how to solve this?
Using JBPM 4.3, Spring 3.0.0, Hibernate 3.3.1, MSSQL Server.
