Hello,
I have been away from WO for sometime and I picked it up again today.
I am having a problem that any instance variable or method I add using
WOBuilder to my Main component can not be found during runtime, but I
see the method and instance code add to main.java . Note that the access
level of the Person class is public,
the instance variable aPerson in Main.java is public and the method
addPerson in Main.java is public.
Here is the errors I am getting
For a instance variable
--------------------------------------------------------
Error:
com.webobjects.foundation.NSKeyValueCoding$UnknownKeyException: [
valueForKey()]: lookup of unknown key: 'aPerson'. This WOComponent does
not have an instance variable of the name aPerson or _aPerson, nor a
method of the name aPerson, _aPerson, getAPerson, or _getAPerson
Reason:
[<Main name: Main subcomponents: null > valueForKey()]: lookup of
unknown key: 'aPerson'. This WOComponent does not have an instance
variable of the name aPerson or _aPerson, nor a method of the name
aPerson, _aPerson, getAPerson, or _getAPerson
------------------------------------------------------------------------------------------
or if I do not used the instance variable in the Main component and just
have a form with a addPerson action I get :
Error:
com.webobjects.foundation.NSKeyValueCoding$UnknownKeyException: [
valueForKey()]: lookup of unknown key: 'addPerson'. This WOComponent
does not have an instance variable of the name addPerson or _addPerson,
nor a method of the name addPerson, _addPerson, getAddPerson, or
_getAddPerson
Reason:
[<Main name: Main subcomponents: null > valueForKey()]: lookup of
unknown key: 'addPerson'. This WOComponent does not have an instance
variable of the name addPerson or _addPerson, nor a method of the name
addPerson, _addPerson, getAddPerson, or _getAddPerson
my main.java code
import com.webobjects.foundation.*;
import com.webobjects.appserver.*;
import com.webobjects.eocontrol.*;
import com.webobjects.eoaccess.*;
public class Main extends WOComponent {
public Person aPerson;
public Main(WOContext context) {
super(context);
//aPerson = new Person();
}
public WOComponent addPerson()
{
//aPerson = new Person();
return null;
}
}
Any ideas…..
Thank you,
Richard Whittaker
