Re: ClassCastException in some browser, but not others (

OK, this works --> IDBDatabase idb = Js.<IDBDatabase> uncheckedCast(idbr.result);

		@SuppressWarnings({ "unchecked" })  	public static void initIndexedDb() {    		IDBFactory idbf = IndexedDbGlobal.indexedDB;  		IDBOpenDBRequest idbr = idbf.open(INDEXEDDB_NAME);  		  		idbr.onsuccess = new OnsuccessFn() {    			@Override  			public Object onInvoke(elemental2.dom.Event p0) {    				// fails w java.lang.ClassCastException  				// IDBDatabase idb = (IDBDatabase) idbr.result;  				// IDBDatabase idb = Js.<IDBDatabase> cast(db);    				//this works  				IDBDatabase idb = Js.<IDBDatabase> uncheckedCast(idbr.result);    				DOMStringList dsl = idb.objectStoreNames;    				dsl.asList().forEach(s -> {  					Log.info("FOUND DB " + s);  				});    				return idbr.result;  			}  		};    		idbr.onerror = new OnerrorFn() {    			@Override  			public Object onInvoke(elemental2.dom.Event p0) {  				Log.error("OnerrorFn " + p0.type);  				return null;  			}  		};  	}

Meant to add that I am sure indexeddb is supported in all the browsers I am using.

Here is the code again ... sorry about the previous formatting.

IDBFactory idbf = IndexedDbGlobal.indexedDB;

IDBOpenDBRequest idbr = idbf.open(INDEXEDDB_NAME);

 

idbr.onsuccess = new OnsuccessFn() {

@Override

public Object onInvoke(elemental2.dom.Event p0) {

 

                                        //error is next

idb = (IDBDatabase)  idbr.result;

DOMStringList dsl = idb.objectStoreNames;

dsl.asList().forEach(s -> {

Log.error("FOUND DB " + s);

});

 

return idbr.result;

}

};

On Chrome desktop, I find the indexeddb I created in handwritten js code.  I don't get why there is a ClassCastException in some browsers.  Is elemental2-indexeddb or gxt 2.9 (HEAD) not supported everywhere?
