Hi,
I've been searching around the documentation, tutorials and forums (for two days) to try to understand how I specify parameters to the HQL activity where the value is defined in the execution context.
I'm using jBPM 4.4 and JBoss EAP 5.0.
I've tried to specify my HQL node in various fashions bearing in mind there is a executionContext var called invoiceId and it is a Long: -
<hql name="Check invoice" g="258,162,117,52" var="invoice" unique="true">
<query>from Invoice i where i.invoiceId = :invoiceId</query>
<parameters>
<string name="invoiceId" value="#{invoiceId}" />
</parameters>
<transition name="Check paid" to="Paid?" g="-62,-4"/>
</hql>
This tries to pass the text as a String with the value "#{invoiceId}"
If i try to do this with a <long /> then it won't even deploy my process.
It seemed like i should use a reference as follows: -
<hql name="Check invoice" g="258,162,117,52" var="invoice" unique="true"> <query>from Invoice i where i.invoiceId = :invoiceId</query> <parameters>
<ref object="invoiceId" />
</parameters>
<transition name="Check paid" to="Paid?" g="-62,-4"/>
</hql>
but this fails because org.jbpm.jpdl.internal.activity.HQLActivity uses the set named parameter methods and there is no way to pass anonymous parameters. It is an anonymous parameter because the ReferenceDescriptor class returns null for getName() and there is no way to specify a name for <ref /> under the http://jbpm.org/4.4/jpdl http://jbpm.org/4.4/jpdl namespace.
According to this feature request https://jira.jboss.org/browse/JBPM-2279 https://jira.jboss.org/browse/JBPM-2279 we should be able to use EL but there is no reference in the documentation as to how.
Can anyone help?
P.S sorry if this comes out badly formatted, it's my first post.
James

Hi, I'm trying to put an EAR file on the server (EJB+JPA) but it's giving me the following error. I put the MYSQL connector in the deploy folder, since it didn't seem to be recognising the datasource, but no luck...I'm using JBoss 5.1.0 and Eclipse Helios
