If ViewModel's property is a map, we can write:

<label value="@load(vm.myMapping['myKey'])"/>

But then, when we need to update the label, we must write:

BindUtils.postNotifyChange(null, null, this, "myMapping");

So all properties from myMapping in the View will be updated instead of one - myKey. It would be great if the property in this model was myKey, so we can write:

BindUtils.postNotifyChange(null, null, this, "myKey");

Even for a lable like:

<label value="@load(vm.myFunction('myKey'))"/>

It would be great if in ViewModel we can define two methods:

Object getProperty(String name)
void setProperty(String name, Object value)

So in View we can call:

<label value="@load(vm.myKey)"/>
