Maybe i don't know how to do it but it seems strange to me. I have, lets say, a textbox with the following binding:

<textbox value"@load(vm.store.shoppingCart.itemsCount)" />

As soon as i open the page everything works fine and the textbox displays the correct number of items in the cart. Now, if i modify the ShoppingCart's contents the @NotifyChange does not reflect the changes back to the page:

public void addItem(Item item) {

What am i doing wrong? The only solution i found was to add the 'dummy' getter getCartItemsCount() directly into the ViewModel and bind the textbox to this getter:


Another way is to make a @NotifyChange(".") but this is to 'heavy' for my page. Is there any other way so that the @NotifyChange mechanism can resolve the properties path?

Thank you all /costas

I had the same problem. But just to close, i used @NotifyChange(".") .

Currently VM will not "Chain" the getters,

the code


probably mapped to

public ??? getStore.shoppingCart.itemsCount () // just guess, not sure

change the NotifyChange as below then it should work:

@NotifyChange("store") // vm.getStore()

Acc. to my understanding,itemscount is a variable in your shoppingCart bean object.you are calling some method to add a item,that doesn't change the itemscount. You have to elaborate a more for better understanding.still try using:-

BindUtils.postNotifyChange(null, null, this.store.shoppingCart, "*");

inside add item method.

this should never work,please check postNotifyChange() method again and also check @benbai answer.
