[jboss-user] [JBoss Seam] - Howto handle LazyInitializationException

Hello I have a problem with lazy loading and need a workaround. I have an Entity called SoftwareInventoryObject which contains a Collection of SoftwareInventoryObjectParts. | class SoftwareInventoryObject { | // other fields | List<SoftwareInventoryObjectPart> parts; | | // Getter & Setter | } | Additionally I have a EJB3 Bean SoftwareObjectSearch which searchs in the database for the above mentioned SoftwareInventoryObjects. | class SoftwareObjectSearch { | // other code | | @DataModel | List<SoftwareObjectPart> inventoryObjects; | | // other code | } | To view the result I have a facelet which contains a <h:dataTable>. Now I would like to display each of the SoftwareObjectParts too therefor I have a nested <h:dataTable> in the facelet. | <h:dataTable value="#{inventoryObjects}" var="sio" rendered="#{inventoryObjects != null}"> | <h:column> | <h:dataTable value="#{sio.parts}" var="siop"> | <h:column><f:facet name="header">Name</f:facet> #{sio.name}</h:column> | <h:column><f:facet name="header">Type</f:facet> #{sio.type}</h:column> | <h:column><f:facet name="header">Barcode</f:facet> #{sio.barcode}</h:column> | <h:column><f:facet name="header">Manufacture</f:facet> #{sio.manufacture}</h:column> | <h:column><f:facet name="header">Distributor</f:facet> #{siop.distributor}</h:column> | <h:column><f:facet name="header">Order Number</f:facet> #{siop.orderNumber}</h:column> | <h:column><f:facet name="header">Price</f:facet> #{siop.price}</h:column> | <h:column><f:facet name="header">Version</f:facet> #{siop.version}</h:column> | <h:column><f:facet name="header">Action</f:facet> link</h:column> | </h:dataTable> | </h:column> | </h:dataTable> | Now when I run a facelet I get a Lazy Initalization Exception for the siop, the SoftwareInventoryObjectPart. This makes sense to me, because I access a collection which is not eager loaded, after the initial Hibernate session was closed. My question is now, how can I avoid such an exception? What is a nice workaround. If you need any further code please let me know. Thanks for all the answers in advance.
