Hello List,
Not easy to summarize this issue in the title
anyway.
I am facing an irritating behavior with a pojo that I want to modify in a
form.
This pojo implements a generic interface that forces the implementation of a
getter and a setter.
If I try to link the value of a TextField to the property handled by this
getter I get a happy
org.apache.tapestry5.ioc.internal.util.TapestryException
Like :
org.apache.tapestry5.ioc.internal.util.TapestryException: Parameter
'translate' of component admin/Tasks:taskedit.taskeditform.foreignid is
bound to null. This parameter is not allowed to be null. [at
classpath:com/marketip/geoplanning/web/components/admin/TaskEditForm.tml,
line 138]
Heres a sample :
Interface :
public interface Identifiable<T> {
public T getId();
public void setId(T id);
}
Pojo :
public class MyPojo implements Identifiable <String> {
public String id;
public String name;
public String getId() {
return this.id;
}
public void setId(String id) {
this.id = id;
}
public Strign getName() {
return this.name;
}
public void setName(Strign name) {
this.name = name;
}
}
TML :
<t:form t:id="myForm">
<t:textfield t:id="pojoId" t:value="myPojoInstance.id" />
<t:textfield t:id="pojoName" t:value="myPojoInstance.name"
/>
</t:form>
=> this will show the above exception at render time, and simply removing
the implements Identifiable<String> of the MyPojo class will make
everything running just fine.
Above all, I dont have the problem when running the application on Jetty
(Eclipse plugin) but I do have the problem when deploying the application on
a Tomcat 6.
Does anyone have an idea ?
Thanks,
Nicolas Gillet
