Hi all-
I have this piece of html going against the "testForm" form bean that is
declared for that page. It calls the getTest method.
<bean:write name="testForm" property="test" filter="true"/>
causes
public String getTest()
{
return "Test called";
}
to be called. hence, it seems like fields can be calculated and may not have
value holding variables.
So I try the same thing with an array. First I create a dummy object to
store in the array.
class Person
{
String name;
Person(String name)
{
this.name = name;
}
public void setName(String name)
{
this.name = name;
}
public String getName()
{
return this.name;
}
}
Then I create the following in the "testForm" form bean.
public Person[] getPersons()
{
Person[] result = new Person[3];
result[0] = new Person("this");
result[1] = new Person("that");
result[2] = new Person("other");
return result;
}
But when I try to access this calculated "persons" property as follows
<logic:iterate id="person" name="testForm" property="persons">
<bean:write name="person" property="name" filter="true"/>
</p>
</logic:iterate>
I get "Cannot find bean person in scope null". Can someone point me what I
am doing wrong here?
The reasoning behind using calculated properties versus real ones is to
avoid nested collections and loading all at once after a successful login.
Also this will free me from maintaining the relations and updates in
memory/underlying db, and I will treat every record and their operations in
an atomic manner.
Thanks,
