Hello,
i do have a little problem with the upgrade to HibernateEntity.
a ClassCastException: java.lang.String is raised at org.hibernate.type.LongType.set(LongType.java:42)
see below.
My question: how must an id of type other than String be handled? The idclass seems to be gone.
My configuration in components.xml:
| <factory name="bazProject" value="#{bazProjectHome.instance}"/>
| <component name="bazProjectHome" class="org.jboss.seam.framework.HibernateEntityHome">
| <property name="entityClass">de.bafz.lims.model.Project</property>
| <property name="session">#{bazDatabase}</property>
| <property name="id">#{bazProjectID}</property>
| </component>
| <factory name="bazExperiment" value="#{bazExperimentHome.instance}"/>
| <component name="bazExperimentHome" class="org.jboss.seam.framework.HibernateEntityHome">
| <property name="entityClass">de.bafz.lims.model.Experiment</property>
| <property name="session">#{bazDatabase}</property>
| <property name="id">#{bazExperimentID}</property>
| </component>
|
|
bazProject works fine. bazExperiment raises the exception.
This is the configuration i used for ManagedHibernateEntity(this was replaced by HibernateEntity)
| <component name="bazProject" class="org.jboss.seam.core.ManagedHibernateEntity">
| <property name="entityClass">de.bafz.lims.model.Project</property>
| <property name="session">#{bazDatabase}</property>
| <property name="id">#{bazProjectID}</property>
| <property name="idClass">java.lang.String</property>
| </component>
| <component name="bazExperiment" class="org.jboss.seam.core.ManagedHibernateEntity">
| <property name="entityClass">de.bafz.lims.model.Experiment</property>
| <property name="session">#{bazDatabase}</property>
| <property name="id">#{bazExperimentID}</property>
| <property name="idClass">java.lang.Long</property>
| </component>
|
|
the end of the stacktrace:
