FXML expression binding

[Philipp Dörfler]

More news:

<CheckBox selected="${(boxA.selected &amp;&amp; boxB.selected) || boxC.selected}" />

note the &amp;&amp; instead of && for XML goodness.
Also note that operator precedence is somewhat different from what you might be used:

! boxD.selected && boxE.selected seems to be: !(boxD.selected && boxE.selected)

so:

! true && false evaluates to true


I conclude that FXML expression binding supports more than the most basic expressions but it is nowhere documented which ones exactly.
I am curious what other expressions are supported.
