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.
Thierry
