JDK-8101924 - Improve api docs for snapshot
Description
If I take a snapshot of a piechart, the labels of the pie slices are shown, but the colored slices are not.

Attached is a sample test case (PieChartExport.java), which captures a snapshot image then renders it - the rendered image should look like a PieChart, but it does not.  Sample output of the test case is also attached (missingslices.PNG).
Comments
I agree that this issue can be resolved now.

Documentation regarding interaction of snapshots and scene attachment as well as snapshots of animated nodes such as charts was added to the snapshot 2.2 API docs (http://docs.oracle.com/javafx/2/api/javafx/scene/Node.html#snapshot%28javafx.scene.SnapshotParameters,%20javafx.scene.image.WritableImage%29). I think this issue can be closed, or is some other change still intended here?

As part of finishing the API docs for snapshot, this limitation will be documented.

This is a known limitation in CSS and layout processing. In order for either to work correctly for Node.snapshot(), the node in question must be attached to a Scene. The scene need not be attached to a Stage, so the following is sufficient, added any time after the chartContainer is constructed and before snapshot is called: Scene snapshotScene = new Scene(chartContainer);
