<span style="font-size: 14px;">Hi John,</span>
<div><span style="font-size: 14px;"><br>
</span></div>
<div><span style="font-size: 14px;"> This looks like a user code issue and not a JavaFX bug.</span></div>
<div><span style="font-size: 14px;"> Most of the vertical scrollbar issues that you have mentioned get fixed by adding a call to "super.updateItem(image, empty);" as a first call in the cell factory method "<span style="white-space: pre; background-color: rgb(255, 255, 255);">protected
void </span><span style="white-space: pre; background-color: rgb(255, 255, 255);">updateItem</span><span style="white-space: pre; background-color: rgb(255, 255, 255);">(</span><span style="white-space: pre; background-color: rgb(255, 255, 255);">Image
</span><span style="white-space: pre; background-color: rgb(255, 255, 255);">image,
</span><span style="white-space: pre; background-color: rgb(255, 255, 255);">boolean
</span><span style="white-space: pre; background-color: rgb(255, 255, 255);">empty)</span><span style="white-space: pre;">”</span></span></div>
<div><br>
</div>
<div><span style="white-space: pre; background-color: rgb(255, 255, 255); font-size: 14px;">I am seeing an exception when I scroll fully down and then scroll up by clicking empty area on the vertical scrollbar. This looks like a separate issue though.</span></div>
<div><span style="white-space: pre; background-color: rgb(255, 255, 255); font-size: 14px;"><br>
</span></div>
<div><span style="white-space: pre; background-color: rgb(255, 255, 255); font-size: 14px;">Regards,</span></div>
<div><span style="white-space: pre; background-color: rgb(255, 255, 255); font-size: 14px;">Ajit</span></div>

<span style="font-size: 11pt;">What you have should work, but will create redundant images and<span class="Apple-converted-space"> </span><br>
ImageView ojbects. The recommendation is to create the nodes (ImageView<span class="Apple-converted-space"> </span><br>
in this case) in the constructor of the cell factory and call setGraphic<span class="Apple-converted-space"> </span><br>
with either null or that factory's node.<br>
<br>
Having said that, I doubt that this is related to the visual problems<span class="Apple-converted-space"> </span><br>
you are seeing. Maybe Ajit or Andy have some ideas.<br>
