Я столкнулся с этой проблемой при попытке использовать cellData -> cellData.getValue () для добавления атрибута из объекта, атрибут является StringProperty, и у меня есть метод для его возврата, и я использую его вcellData -> cellData.getValue (). methodtoreturnproperty, но он все еще дает мне java.lang.reflect.InvocationTargetException, кто-нибудь знает, что я делаю неправильно?Вот код:
package projeto.resources;

Есть класс под названием Sala, который импортируется в этот контроллер, я мог бы заставить его работать с другим классом, называемым Filmes, я не знаю точно, почему он не работает с классомСала, вот код в классе:
package projeto;
import javafx.beans.property.SimpleStringProperty;
import javafx.beans.property.StringProperty;
public class Sala {
private boolean e3d;
private int assentosMax;
private int assentosDisp;
private final StringProperty numeroProperty = new SimpleStringProperty();
public Sala(boolean e3d, int assentosMax, int assentosDisp, String numero) {
setNumero(numero);
e3d = this.e3d;
assentosMax = this.assentosMax;
assentosDisp = this.assentosDisp;
}
public boolean isE3d() {
return e3d;
}
public void setE3d(boolean e3d) {
this.e3d = e3d;
}
public int getAssentosMax() {
return assentosMax;
}
public void setAssentosMax(int assentosMax) {
this.assentosMax = assentosMax;
}
public int getAssentosDisp() {
return assentosDisp;
}
public void setAssentosDisp(int assentosDisp) {
this.assentosDisp = assentosDisp;
}
public StringProperty numeroProperty() {
return numeroProperty;
}
public final String getNumero() {
return numeroProperty.get();
}
public final void setNumero(String numero) {
numeroProperty().set(numero);
}
}
Редактировать: Вот ошибка:
