Hi,
I am playing around with the Seam remoting. I am playing with the helloworld
seam application:
I am attempting to pass a seam object (JavaBean) from the browser to the
backend. When invoking the method with the parameter, the method is called, but
the object is not populated with any values.
In short I have the following:
1. The Javabean:
@Name("person")
| public class Person implements Serializable{
|
| Integer id;
| String name;
| String surname;
| //with getters and setters
| }
2. The method definition in the interface (HelloLocal):
| @WebRemote
| public void setPerson(String value, Person person);
|
3. The implementation (HelloAction):
| public void setPerson(String value, Person person) {
| System.out.println("Received value: " + value);
|
| System.out.println("Received from xhtml page " + person.getName() + " "
+ person.getSurname());
| }
4. My Javascript being called in the xhtml:
| function sayHello() {
| var p = Seam.Component.newInstance("person");
| p.setId(15);
| p.setName("from");
| p.setSurname("sayHello");
| Seam.Component.getInstance("helloAction").setPerson("from
sayhello", p);
| }
When I invoke the sayHello javascript I see the following in the debug window:
| Thu Jan 25 2007 13:44:32 GMT+0200 (SAST): Request packet:
| <envelope><header><context></context></header><body><call
component="helloAction" method="setPerson" id="1">
| <params><param><str>dummyvalue</str></param><param><ref
id="0"/></param></params><refs><ref id="0"><bean type="person">
| <member name="id"><number>15</number></member>
| <member name="name"><str>from</str></member>
| <member name="surname"><str>sayHello</str></member>
| </bean></ref></refs></call></body></envelope>
which is the correct values passed to the backend. Unfortunately the person
object is not populated, while the string value is sent correctly. The result:
| 3:57:37,988 INFO [STDOUT] Received value: from sayhello
| 13:57:37,990 INFO [STDOUT] Received from xhtml page null null
|
Any suggestions as to why I am not able to send an object as paramter to the
server? Interestingly enough I am able to send a person object (created on the
backend and returned with "public Person getPerson()" ) to the javascript.
Thanks
Louis
