Control Bindings

Aria 4.5 will extends the data binding facilities of early version by adding inline data bindings. These inline bindings are specified by adding a "bind" attribute to any control.

The new bind attribute can include references to other controls or widgets from the current page. The control bindings can also specify properties of the bound widget using the usual dot notation.

The control bindings automatically update as input is detected. Usually data bindings require a call to saveBoundComponentValues or updateBoundComponentValues to be invoked, however the control bindings add listeners for changes to the state of thesource control and force an update.

The inline binidngs can also specify nodes from the data model as a shortcut and alternative to the normal data binding specification.

In the case of a control binding the Aria framework actually sets up two bindings, a source binding that outputs data to a model node on the path /inline//, this model node is then used as the source of the data for the target binding. The use of the data model in this way means that your code can easily interact with these data bindings too.
