------------------------------------

Hi Michael,

When the improvement is completed, we can put widget form and grid in the same page for editing.

Like KnockoutJS, a data-bind attribute is used for declaring the behaviours of the widget field.

The behaviours occur only at the browser, Some possible benefits include:
 # Binding the field’s value to a javascript map which we can use to submit the changes to the server.
 # Rendering the table rows at the browser side. Adding and removing rows are done in situ.
 # Displaying rows total sum. Compute on the fly when any of the dependent value changes.

ViewModel of the MV(VM) handles the heavy lifting to support the declared behaviours. ViewModel is defined in Javascript in an ftl file under platform-specific html tag, and can be replaced with a customised implementation.
