[jboss-user] [JBoss Seam] - Re: Challenge: Simple Example Adding Records With Lookup Dro
No problem.
But ... erm ... I've another question: In my application there is a table which
contains priorities. The table contains two columns: the ID and the description
of the priority. On some pages the user can filter all shown entries by
priority. Adding a noSelectionLabel the user has also the option to disable the
filtering.
But now the user should be able to filter for priorities greater or less than a
distinct value, say 3. So I want to add two further rows in the si:selectItems
which have this special meaning. I know that the EntityConverter can't handle
rows, which are created in my bean and not persisted in the database.
So I think the best solution would be a custom converter which handles the
special meanings and invokes the EntityConverter for all the other cases.
Is that possible?
Has to be something like this (got it from the wiki):
public Converter getPriorityConverter() {
|return new PriorityConverterPriority() {
|
| protected Object getIdAsObject(String id, Class clazz) {
| int priority = Integer.parseInt(id);
| if(priority == -2) return SpecialPriorities.GREATER_3;
| if(priority == -3) return SpecialPriorities.LESS_3;
| Converter entityConverter = new EntityConverter();
| return entityConverter.getIdAsObject(id, clazz);
| }
|
| protected String getIdAsString(Priority entity) {
| return entity.getId() + ( + entity.getDescription() + );
| }
|};
| }

Nope, that won't work. A converter probably isn't suitable here. This, to me, sounds like a good use for returning the key directly to the backing bean. I've added an example to the wiki on doing this.

Ah. OK. I didn't set this value in persistence.xml. What does this property do? I try to explain it for my own: In persistence.xml I'm setting up how to connect the database. Whit the property you mentioned I give it a JNDI name?!? And this JNDI name is the value that is needed by the SelectItemsConfig. Right? BTW: I just use the annotation @PersistenceContext(name=aresDatabase) to inject the EntityManager in each component that needs the EntityManager. I saw some guys using only the @In annotation. Why does it work for them? Does it have to do with the org.jboss.seam.core.ManagedPersistenceContext property in components.xml? Where do I find more to read on this topic?

[jboss-user] [JBoss Seam] - Re: Challenge: Simple Example Adding Records With Lookup Dro
property name=jboss.entity.manager.factory.jndi.name value=.../ causes jboss to publish an EntityManagerFactory in JNDI for this PersistenceContext. As I mentioned above EntityConverter requires access to your EntityManager. You tell SelectItemsConfig the name under which the EntityManagerFactory is published in JNDI, the EntityConverter can then do a JNDI lookup for this factory, and thus create an EntityManager. SelectItemsConfig is just a simple bean which can be configured by components.xml and then read by the various other classes (which aren't Seam components so can't be configured by components.xml directly) If you want to @In your EntityManager you need to configure a Seam Managed Persistence Context, this is covered in the reference manual. http://docs.jboss.com/seam/1.1CR1/reference/en/html/configuration.html#d0e6249 View the original post : http://www.jboss.com/index.html?module=bbop=viewtopicp=3988179#3988179 Reply to the post : http://www.jboss.com/index.html?module=bbop=postingmode=replyp=3988179 ___ jboss-user mailing list jboss-user@lists.jboss.org https://lists.jboss.org/mailman/listinfo/jboss-user

[jboss-user] [JBoss Seam] - Re: Challenge: Simple Example Adding Records With Lookup Dro
I've got an appointment so I quickly wrote down what I've done: 1. Download selectitems.jar and selectitems-ui.jar. 2. Place them in WEB-INF/lib of your war file. 3. Add following property to your persistence.xml: property name=jboss.entity.manager.factory.jndi.name value=java:/selectItemsEntityManagerFactory/ 4. Add following entry to your components.xml: component class=org.jboss.seam.selectitems.SelectItemsConfig | property name=persistenceUnitJndiNamejava:/selectItemsEntityManagerFactory/property | /component As you might guess the property has to be the same value you set in persistence.xml. 5. Now you can establish the relationships between your entities using @OneToOne and so on. (Don't forget to adjust getters and setters) 6. The method which outjected the SelectItems can now be rewritten to outject an list containing the entities. 7. Use si:selectItems to retrive the entities. With attribute label you can define the label shown on each row. To use si you have to include xmlns:si=http://jboss.com/products/seam/selectitems/taglib; and xmlns:s=http://jboss.com/products/seam/taglib; You have to use attributes Value, var and label.

Well there are really two approaches: 1) Traditional JSF - write a converter and outject a List - this is described on the wiki http://wiki.jboss.org/wiki/Wiki.jsp?page=SelectItems 2) Use the SeamSelectItems package - an old version of which is being discussed here View the original post : http://www.jboss.com/index.html?module=bbop=viewtopicp=3987907#3987907 Reply to the post : http://www.jboss.com/index.html?module=bbop=postingmode=replyp=3987907 ___ jboss-user mailing list jboss-user@lists.jboss.org https://lists.jboss.org/mailman/listinfo/jboss-user

I was able to get the example working after closely following your example Mr.
Muir. Thank you.
In your example you have Client and ClientType POJO's. My next hurdle is
getting the Client object to persist from a JSF. Is there an example already
out there showing how to persist an object that has a dropdown/lookup,
reference as an @ManyToOne?
My JSF seems to pass validation, however I keep getting
unable to access entity manager
as a return message in my JSF. No exceptions come up the stack trace and the
action event never gets called. So, some magic is happening between jsf submit
and RoomServiceBean.

I should also say, that the rooms and organization lookups work fine using the EntityManager from inside RoomServiceBean. But it appears that the the jsf is trying to access the EntityManager from somewhere other than than RoomServiceBean, because I get no System.out messages once I click on the roomService.addNewPerson button.

Wow, I get to answer my own question for a change:
The validation error was resolved when I read the example by Mr. Muir. I had to
override the equals method:
| @Override
| public boolean equals(Object obj) {
| if (!(obj != null obj instanceof Room))
| return false;
| Room rm = (Room) obj;
|
| if (this.id.equals(rm.id))
| return true;
|
| return false;
| }
|
The next problem I got I fixed reading another forum post.. changing the
entityManager.persist to entitymanager.merge
I GOT THE Record to ADD!!

Thanks petemuir. I think you've got me on the right track now. Getting that old
null exception again. I've debuged the code and I have exactly 3 rooms in my
lists. The count says 3.

[jboss-user] [JBoss Seam] - Re: Challenge: Simple Example Adding Records With Lookup Dro
I'm still concerned about personEditor having a SESSION scope [1]. I would
suggest trying a really simple stateless session bean that just returns all the
rooms in your data:
...
| @SelectItems(label=description)
| ListRoom allRooms;
|
| @Factory(allRooms)
| void getRoomList() {
|allRooms = entityManager.createQuery(select room from Room
room).getResultList();
| }
| ...
and see if you can get that displaying on your JSF page. Then work up from
there.
In general I would suggest always using much simpler jsf/beans whilst debugging
something like this and working up to a complex setup - something else could be
causing the problem but be hidden.
The example is probably a good place to start - the only reason the backing
bean is conversational is to show state being saved, the interesting stuff
(@SelectItems) could easily be stateless.

[jboss-user] [JBoss Seam] - Re: Challenge: Simple Example Adding Records With Lookup Dro
Thanks. Looks like my decision to add to the already generated code was a bad idea. I like your idea of simplifying. So that brings me to a design question: In this case should I create a new SLSB to persist the new person record rather than the generated PersonEditorBen(SFSB)? If I do create a new SLSB, can I make it do the room lookup, extract the data from jsp and add the record to the person table. Or, does this SLSB need be to specifically for the room lookup? If so, do I always need to user SLSB when doing fancy dropdown lookups on tables? In Seam what are the best guidelines for determining when/when not to use SLSB/SFSB?

anonymous wrote : In Seam what are the best guidelines for determining when/when not to use SLSB/SFSB? This is an interesting question. I think the answer depends on style/what you are doing. I'm increasingly using the pattern of a stateful component to manage the flow and a stateless 'service' bean to do the rest of the work. I use bijection to pass any object required (so far only entities) between them. The advantage of this approach I find is that, firstly, you seperate workflow logic from 'helper' methods resulting in clearer code (for example, deleting a user vs. reseting the password), secondly, it makes the 'helper' methods resuable (e.g. a nationality dropdown might be used in various places in your ui, so you want its content to be generated in a stateless fashion). The disadvantage is complexity - and I am developing a complex workflow involving jbpm. So, what I would do is create a 'roomService' bean which contains any non-workflow-related methods for rooms (e.g. drop down lists, generating access codes), and a 'roomCRUD' bean that contains the workflow methods. That doesn't mean its the best approach but it works well for me and avoids a lot of the concurrent access problems to stateful beans (though I believe the new seam fixes this).

[jboss-user] [JBoss Seam] - Re: Challenge: Simple Example Adding Records With Lookup Dro
Have you tried the example in my selectitems code (http://jroller.com/page/pmuir?entry=selectitems_revisited). It contains both a select many and select one drop down that will end up being represented as youy suggest. If you have problems getting the example running (follow the readme) let me know. There are a couple of bugs in it which I plan to fix later today.
