manage sub-collection with grid component
Dear all,
I need your support in order to determine the better way to solve this
situation.
I have, say, 2 entities (ejb3)
@Entity
public class Child {
private String idChild;
private String firstName;
private String secondName;
...
}
@Entity
public class Father{
private String idFather;
private CollectionChild children;
...
}
And I want to build a table in this way:
- for each row, print all Father properties
- in the last column, I want to insert a list of links to the each child
related to the specific Father in the row.
I'm working on a grid component, so:
t:grid t:id=Father add=childrenInfo/
but what can I insert in the childrenInfo column?
I think that one solution could be a new component that accepts the idFather
as parameter, and then returns the html code for the Children list. Is this
a good idea?
Any suggestions/thoughts?

Re: ActionLink in component
maybe you can try to be more specific in this way:
${index}/t:comp
@OnEvent(value = action, component = select)
void valueChosen(int value)
{
this.value = value;
}
Here you can find more explanation:

Yes, they are both persisted. tableParsed is set to true after a file was
uploaded and parsed success
fully. This variable is then used to show the next step of this process
which requires the table to be parsed.
The whole thing works well except that after the process is finished I
have
to restart jetty or wait until the session has expired. :-(
When I change the OnEvent annotation to component unspecific by removing
(component=reset), the reset() method is triggered, but then I never
reach
the second step. The method is then triggered when uploading the file.

Are tableParsed and saveSucceed @Persist'ed?

Re: problem beaneditform and external ejb3
I think I'm really close to the solution, after some modifications I can see
the beaneditform in my page, but it's completly empty (I mean, only the
Create/Update button is shown).
Here my complete code:
//DuckBeanRemote represents the Remote Interface of one stateless session
bean.

AddOperator.java
public class AddOperator{
private DuckBeanRemote dao;

private Operator operator;
public AddOperator(){
// obtaining a dao from the context
try {dao = (DuckBeanRemote)new
javax.naming.InitialContext().lookup(DuckBean/remote);
}catch(Exception e){e.toString();}
}
public void setOperator(Operator operator) {this.operator = operator;}
public Operator getOperator() {return operator;}
// I create an instance of Operator
void onActivate(){operator= new Operator();}
Object onSubmitFromOperatorEditor() {
dao.addOperator(operator);
return ShowOperators.class;
}
}
This is what I can see in the jboss logs

Re: problem beaneditform and external ejb3
PROBLEM FOUND!
The beaneditform component can't understand this type of setter methods:
public String getUsername(){return username;}
public Operator setUsername(String username){this.username=username;return
this;}
I changed the setter in this way:
public void setUsername(String username){this.username=username;}
and everything is working now.
I usually define setters in this way in order to write something like this:
Operator operator = new
Operator().setUsername().setPwd().setThis(..).setThat(..);
So, how can I manage this kind of setters in Tapestry 5? any suggestion?
do I really have to change all my setter methods?!?!? :,(

Re: problem beaneditform and external ejb3
@Thiango: I use the ejb3 business logic as a stand alone project (I mean, another folder in the workspace), separeted by the Tapestry one. I deploy it indipendently in JBoss and than a war for the Tapestry project. @Geoff: thanks for the jumpstart examples, but I already read them, but my problem is a bit different. Let me explain: I can use entity beans without any problem with the grid component and other components that can obtain a specific instance of the object. In particular, I call a page with a PageLink and I do something like dao.findOperator(username) in the onActivate() method, and the grid (for example) works perfectly. The problem with the beaneditform is that I want Tapestry to create an empty instance of my entity bean, but at the moment he can't understand what type he has to use (in this case, Operator).

problem beaneditform and external ejb3
Hello everybody, I'm new to Tapestry 5 and I need help to solve a problem. I defined an entity bean Operator in my ejb3 project, and I want it to be the object of a beaneditform in a Tapestry 5 project. So, I wrote this in the AddOperator.tml page: and I get this Tapestry error: Embedded component 'operatorEditor' has no type. You should specify a type in the component template, or define the component inside class sittingduck.pages.AddOperator using the @Component annotation on a private instance variable. In my understanding, my AddOperator.java seems to be ok because I defined: @Persist private Operator operator; and both setter and getter methods. I tried different ways, like setting a new instance of Operator to the AddOperator page via page injection, or assigning a new instance of Operator to the property field during the onActivate() method of AddOperator page, but no success. Please advise. -- View this message in context: http://www.nabble.com/problem-beaneditform-and-external-ejb3-tp19769807p19769807.html Sent from the Tapestry - User mailing list archive at Nabble.com.
