ok I will give it a try. I did try this but ran into a few problems but based on the two part example from 2009 I see that the custom component extends ERXStatelessComponent.
But then I get this error:
Error: java.lang.IllegalStateException: <<com.as.application.ui.components.NewPublicationContactComponent name: com.as.application.ui.components.NewPublicationContactComponent subcomponents: null >>: A stateless component can not have a stateful child (<er.ajax.AjaxInPlace name: er.ajax.AjaxInPlace subcomponents: null >).
of course if I just extend the component from WOComponent, then it doesn't think I have key():
UnknownKeyException: [<com.as.application.ui.components.NewPublicationContactComponent name: com.as.application.ui.components.NewPublicationContactComponent subcomponents: null > takeValueForKey()]: attempt to assign value to unknown key: 'key'.
This WOComponent does not have an instance variable of the name key or _key, nor a method of the name setKey or _setKey
here is my java from my component.
public class NewPublicationContactComponent extends WOComponent {
public NewPublicationContactComponent(WOContext context) {
super(context);
}
public EOEnterpriseObject object() {
return (EOEnterpriseObject)valueForBinding("object");
}
public String key() {
return (String)valueForBinding(key());
}
public String displayValue() {
return (String)object().valueForKey(key());
}
public WOActionResults saveAfterLeavingInPlaceEditor() {
object().editingContext().saveChanges();
return null;
}
}
There is obviously a lot that I need to learn to use this. I will try again in the morning. My head is just tired.
