EventHandler.getTarget() over Tile throws AssertionError

I'm trying to apply addMouseOverHandler on a Tile in a TileGrid as follow:

addMouseOverHandler(new MouseOverHandler() {
            @Override
            public void onMouseOver(MouseOverEvent event) {
                Canvas tile = EventHandler.getTarget();
                if (tile instanceof SimpleTile) {
                    SC.say(getTileIndex(tile));
                }
            }
        });

and recover the event's target canvas (hopefully a Tile) as has been said here in the forums using EventHandler.getTarget(). If the target is the TileGrid it works. The problem getTarget() throws AssertionError when SmartGWT instance the SimpleTile

SimpleTile.class

 public static SimpleTile getOrCreateRef(JavaScriptObject jsObj) {
        if (jsObj == null) return null;
        final BaseWidget refInstance = BaseWidget.getRef(jsObj);
        if (refInstance == null) {
            return new SimpleTile(jsObj);
        } else {
            [B]assert refInstance instanceof SimpleTile; <= Exception is thrown!![/B]
            return (SimpleTile)refInstance;
        }
    }

In the marked line refInstance is a Canvas instance and the assert fails even when refInstance JSON is:

SimpleTile {
    creator : [TileGrid ID : isc_FotoTileGrid_9],
    canHover : true,
    tileGrid : [TileGrid ID : isc_FotoTileGrid_9],
    ID : "isc_FotoTileGrid_9_tile_2",
    position : "absolute",
    className : "simpleTileOver",
    width : 150,
    height : 168,
    left : 349,
    top : 5,
    styleName : "simpleTileOver",
    tileNum : 2,
    record : Obj {
        ID : 149808
    },
    parentElement : [TileGrid ID : isc_FotoTileGrid_9],
    topElement : [Window ID : isc_FotoPeritacionWindowDynamicForm_0],
    tabIndex : 2628,
    ruleScope : "isc_FotoPeritacionWindowDynamicForm_0",
    cacheOffsetCoords : true,
    showDown : false,
    zIndex : 209630,
    state : "Over",
}

Is this the normal behaviour? If yes, how do you add an over handler to a tile?

Can you show a minimal, ready-to-run test case demonstrating this issue? If this happens every time without special settings, you should be able to quickly reproduce the problem by starting from one of the TileGrid samples.

Test case attached based on basic tiling sample in the showcase just without images and all in one file. The same behaviour happens

We've applied a fix for this issue to SGWT 6.0p and newer that should be in the nightly builds dated 2016-07-18 and beyond.

Thanks fot the fix. Issue solved in the latest patched build 2016-07-18. Just one more question regarding patched builds. I can't use that latest build because now I get a cast exception in setValuesManager. Nothing changed on my code. Just replaced the library. This kind of new weird errors always happen to me when changing the library with the latest patched version even after cleaning the project, browser cache, etc. Is this a normal behaviour with latest patched builds?

Hi hespresati,

it definitely should not happen, but does so from time to time.
This time you had just bad luck, this bug was there only one day (should be gone tomorrow), see here.

Thank you Blama for your answer. I'll try today's patched version hoping I'll have more luck
