Description

I have a screen with 6 PNG images on it (charts)... think of a a graphical dashboard. Now that I upgraded to 1.4.0M1 these images come up very inconsistently. If I refresh these PNG's sometimes appear in the wrong spot (ie. chart 4 will appear 3 times over other charts, in the wrong order...etc). Every time I refresh it seems to change the behavior of where the charts are appearing.

This is how I create the charts using JfreeChart:
EncoderUtil.writeBufferedImage(chart.createBufferedImage(400, 100), "png", response.getOutputStream())

This is how they are displayed:
<img width='400' height='100' src='$

{createLink(controller: 'dashboard', action: 'mail')}

?r=$

{System.currentTimeMillis()}

' />

This worked perfectly in all previous version
