Question

GPS 모니터링 시스템의 프론트 엔드를 개발했습니다. 지오 펜스라는 새로운 기능을 추가해야합니다. 지오 펜스 모델과 PropertyAccess 인터페이스를 만들었습니다.

public class Geofence extends JavaScriptObject { 

protected Geofence() {} 

public final native int getId() /*-{ return this.id; }-*/; 
public final native String getName() /*-{ return this.name; }-*/; 
public final native String getDescription() /*-{ return this.description; }-*/; 
public final native Type getType() /*-{ return this.type; }-*/; 
public final native Coordinate[] getCoordinates() /*-{ return this.coordinates; }-*/; 
public final native double getRadius() /*-{ return this.radius; }-*/; 
public final native int getUserId() /*-{ return this.userId; }-*/; 

public final native void setId(int id) /*-{ this.id = id; }-*/; 
public final native void setName(String name) /*-{ this.name = name; }-*/; 
public final native void setDescription(String description) /*-{ this.description = description; }-*/; 
public final native void setType(Type type) /*-{ this.type = type; }-*/; 
public final native void setCoordinates(Coordinate[] coordinates) /*-{ this.coordinates = coordinates; }-*/; 
public final native void setRadius(double radius) /*-{ this.radius = radius; }-*/; 
public final native void setUserId(int userId) /*-{ this.userId = userId; }-*/; 

public final String getEmpty() { 
    return ""; 
} 
} 

및 속성에 액세스 할 수있는 인터페이스 : 여기

지오 펜스의 모델이다 : 나는이 오류가 프로젝트를 컴파일 할 때 여기

public interface GeofenceProperties extends PropertyAccess<Geofence> {

그러나 변경할 때

Coordinate[] 

List<Coordinate> 

에 모두 잘 작동합니다. 내가 실수 한 곳? ValueProviderCreator.java에서

Answer 1

com.sencha.gxt.data.rebind.PropertyAccessGenerator [ERROR] Generator 'com.sencha.gxt.data.rebind.PropertyAccessGenerator' threw an exception while rebinding 'org.bitbucket.treklab.client.model.GeofenceProperties' java.lang.NullPointerException at com.sencha.gxt.data.rebind.ValueProviderCreator.typesMatch(ValueProviderCreator.java:315)...

:

private boolean typesMatch(JClassType a, JType b) { 
    if (b.isPrimitive() != null) { 
    return a.getQualifiedSourceName().equals(b.isPrimitive().getQualifiedBoxedSourceName()); 
    } else { 
    assert b.isClassOrInterface() != null; 

    return b.isClassOrInterface().isAssignableTo(a); 
    } 
} 

이 코드 (나는 실제로 몇 년 전에 쓴,하지만 난 오늘 센차 작동하지 않습니다)는 가정 하나 여러분의 빈 속성에있는 유형인지 프리미티브 또는 객체 (또는 인터페이스). GWT에서 이것은 배열을 사용할 가능성을 배제합니다. 당신이 변경 얻을 GXT 자체에 버그를 제출해야합니다

public JClassType isClass() { 
    // intentional null 
    return null; 
} 

: GWT의 JArrayType에서. 그러나 어쨌든이 코드는 이후에 작동하지 않을 수도 있습니다. (대부분의 경우 이것이 Can't parse JSON string to Java/JavaScriptObject in GWT의 문제의 근원입니다.)

JavaScript 유형이 아닌 자바 스크립트 유형은 사용할 수 없습니다. GWT의 생성 된 배열 은 거의처럼 js 배열처럼 보이지만 중요한 유형의 세부 정보가 누락되어 java.util.List가 전혀 작동하지 않습니다.

대신 getCoordinates을 JsArray<Coordinate>으로 변경하십시오.
