Re: [T5]: Hibernate question - session is null
Hi,
I also had some trouble configuring hibernate, my session was also null.
After searching for a while I found this tutorial:
http://linuxboy.javaeye.com/blog/68311
Since I dont use a DAO, my code looks something like the following.
my db entity:
...
import org.hibernate.Session;
@Entity
@Table(name = EVENT)
public class EventDBEntity {
public EventDBEntity() {}
public EventDBEntity(Session session) {_session = session;}
@Transient
private Session _session;
// more stuff here.. methods to access the db
...
in my appmodule.java:
...
public static void bind(ServiceBinder binder)
{
binder.bind(TourDBEntity.class);
}
...
then I call an @Inject on the db-entity:
...
// db entity object
@Inject
private EventDBEntity _dbEntity;
// now tapestry injects the hibernate session in my _dbEntity
...
Hope this helps!
Greetings, Mark

Error Adding New Property Editors
Hi,
I want to add a new property editor to show a dropdown-select from a Java List
of Strings.
I dont know where to put my AppPropertyEditBlocks.java and
AppPropertyEditBlocks.tml files.
If I put them under my services, I get the error:
org.apache.tapestry5.internal.services.RenderQueueException
Render queue error in
BeginRender[tour/Request:beaneditform.editor.propertyeditor]: Unable to locate
a block to edit property 'guideList' (with data type 'dropdown') of object
[EMAIL PROTECTED]: Unable to resolve
'AppPropertyEditBlocks' to a known page name. Available page names: (blank),
Appointm.
If I put them under my pages, I get the error:
org.apache.tapestry5.internal.services.RenderQueueException
Render queue error in
BeginRender[tour/Request:beaneditform.editor.propertyeditor]: Unable to locate
a block to edit property 'guideList' (with data type 'dropdown') of object
[EMAIL PROTECTED]: Embedded component
'select' has no type. You should specify a type in the component template, or
define the component inside class
de.startext.tapestry.hida.pages.AppPropertyEditBlocks using the @Component
annotation on a private instance variable.
I added the following lines to my AppModule class:
@SuppressWarnings(unchecked)
public static void
contributeDefaultDataTypeAnalyzer(MappedConfigurationClass, String
configuration)
{
configuration.add(DropDownList.class, dropdown);
}
public void contributeBeanBlockSource(ConfigurationBeanBlockContribution
configuration)
{
configuration.add(new BeanBlockContribution(dropdown,
AppPropertyEditBlocks, dropdown, true));
}
I followed these instructions:
http://tapestry.apache.org/tapestry5/tapestry-core/guide/beaneditform.html
http://wiki.apache.org/tapestry/Tapestry5HowToCreateAPropertyEditBlock
my AppPropertyEditBlocks.java:
public class AppPropertyEditBlocks
{
@Environmental
private PropertyEditContext context;
@SuppressWarnings(unused)
@Component(parameters =
{value=selected,
label=prop:context.label,
encoder=valueEncoderForSelected,
model=selectModelForDropDownList,
validate=prop:context.validator,
clientId=prop:context.propertyId})
private Select selectList;
public PropertyEditContext getContext() { return context; }
public int getSelected() {
return ((DropDownList)this.context.getPropertyValue()).getSelected();
}
public void setSelected(int value) {
((DropDownList)this.context.getPropertyValue()).setSelected(value);
}
@SuppressWarnings(unchecked)
public ValueEncoder getValueEncoderForSelected() {
return new ValueEncoder() {
public String toClient(Object value) { return
((Integer)value).toString();}
public Object toValue(String clientValue) { return new
Integer(clientValue);}
};
}
}
my AppPropertyEditBlocks.tml-file:
div xml:space=default
xmlns:t=http://tapestry.apache.org/schema/tapestry_5_0_0.xsd;
t:block t:id=dropdown
t:label for=select/
input t:id=select/
/t:block
/div
Any help would be great!
Thanks, Mark
