Re: [Gwt-openlayers-users] Any idea's about map.getControls() ?

[Andrew H. <ahh...@gm...>]

I tried the following (in Map):

/**
 * This will fetch all of the controls on the map.
 * @return the Controls or an empty array.
 */
public  Control[] getControls(){
JSObject[] jsObjects = getJSObject().getPropertyAsArray("controls");
int count = jsObjects.length;
Control[] controls = new Control[count];
for(int i =0; i < count ;i++){
controls[i] = Control.narrowToControl(jsObjects[i]);
}
return controls;
}

But this doesn't work, I'm out of my depth with JSNI...

java.lang.IllegalArgumentException: Something other than a Java object
was returned from JSNI method
'@org.gwtopenmaps.openlayers.client.util.JSObjectHelper::getProperty(Lorg/gwtopenmaps/openlayers/client/util/JSObject;Ljava/lang/String;)':
JS value of type int, expected java.lang.Object

	at org.gwtopenmaps.openlayers.client.util.JSObject$.getPropertyAsArray$(JSObject.java:141)

	at org.gwtopenmaps.openlayers.client.Map.getControls(Map.java:124)



Any help would be greatly appreciated :)
