(also for pointing out the use single quote). Now for another one: Application.java has the following accessor method public NSArray<Entree> entrees() { return _entrees; } public void setEntrees(NSArray<Entree> entrees) { _entrees = entrees; }And Main.html has the following subcomponent for which I'm getting the following error message "There is no key 'entrees' for the keypath 'application' in Main"<wo:loop list = "$application.entrees" item = "$currentItem"> I'm sure it's something obvious again, but I can see what.
That warning is normal when you use the default method application() from WOComponent. That method returns an object of type WOApplication that does not have your ivar declared. That ivar is in your Application object. So it is absolutely correct that the component editor displays en error message. To make it disappear you have to either put in a //VALID so the editor ignores that part in the validation process or put the method
@Override
public Application application() {
return (Application) super.application();
}
to typecast your application object into your component or better put
it in a superclass for all your components.
