<p>Is that specific to a Text node? Or what happens if you use a
Label or similar. And also, is the whole node gone or only the
text itself, e.g., what happens if you set a background color for
the node you drag.</p>

<p class="MsoNormal"><b><span style="font-size:11.0pt">Description:<o:p></o:p></span></b></p>
<p class="MsoNormal"><span style="font-size:11.0pt">We have a
use case involving the dragging of text across a Stage. To
support this, we have created a Text object, which is
registered to the root AnchorPane. The Text Object can be
dragged freely around the Stage. However, we've encountered
an issue where the text sometimes fails to render, even
though the Text Object contains the expected data.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">When the
mouse click happens, the current action is:<br>
root.getChildren().remove(dragText);<br>
root.getChildren().add(dragText); <o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">This happens
directly before we start the drag action:<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">dragText.startFullDrag();<o:p></o:p></span></p>

<p class="MsoNormal"><i><span style="font-size:11.0pt">(dragText
is a Text Object)<o:p></o:p></span></i></p>
<p class="MsoNormal"><span style="font-size:11.0pt">The dragText
contains the expected value when the Text object is rendered
or not. The issue seems to be with rendering of the object.
When the issue occurs, the JavaFX application must be
restarted to recover. Have verified:<o:p></o:p></span></p>
