Managed Property Loss Of Visibility

[TA Hubbard]

With jdk-8u20-ea-bin-b05-windows-i586-12_mar_2014, the /managed 
/property appears to be doing double duty.  It is causing the loss of 
visibility when managed is set to false.  I downloaded 
jdk-8-windows-i586 and the issue remains.

This works okay:
<StackPane alignment="CENTER" prefHeight="400.0" prefWidth="400.0" 
xmlns:fx="http://javafx.com/fxml/1">
     <Button text="a button" managed="*true*" visible="true" />
</StackPane>

With this the button is no longer visible.  It should be at the parent 
x=0 and y=0 position:
<StackPane alignment="CENTER" prefHeight="400.0" prefWidth="400.0" 
xmlns:fx="http://javafx.com/fxml/1">
     <Button text="a button" managed="*false*" visible="true" />
</StackPane>

Here, Button has no visibility.  It should be visible at the parent x=15 
and y=15 position:
<StackPane alignment="CENTER" prefHeight="400.0" prefWidth="400.0" 
xmlns:fx="http://javafx.com/fxml/1">
     <Button text="a button" managed="*false*" visible="true" 
translateX="15.0" translateY="15.0" />
</StackPane>

JavaFX JavaDoc states: "/It's the application's responsibility to set 
the size and position of an unmanaged node./"  It is as if the visible 
property is attached to the managed property; you can't see what you are 
managing.  This is a major issue.

Thanks for your attention.
