DWR 3.0.M1: setting img value to bufferedimage

Hi,

I recently switched to dwr3.0.m1 to use the features that have a
built-in converted for BufferedImage, and I've been going by some of the
examples in the .war file to return a BufferedImage and display it on
the page. However, when I run the function that should display the image
on the page, nothing seems to happen, although I have followed the
example in the .war file almost exactly.

Here is the java method signature:

public BufferedImage uploadImage(String cameraName, int cameraFrame)

Here is the javascript source:

            function captureVigraImage() {
                var divElement = document.getElementById('imageCapture1');
                var cameraName = dwr.util.getValue('cameraName2');
                var frameNumber = dwr.util.getValue('channelNumber');
                VigraMain.uploadImage(cameraName, frameNumber,
vigraImageCaptured());
                divElement.innerHTML = "image captured";
            }

            function vigraImageCaptured(data) {
                var divElement = document.getElementById('toReplace1');
                divElement.innerHTML = "callback function";
                dwr.util.setValue('imageCapture2', data);
            }

And finally, here is the relevant html source:

        <h2>Image capture form</h2>
        <form>
            <table>
                <tr>
                    <td>
                        Camera name:
                    </td>
                    <td>
                        <input id="cameraName2" type="text" />
                    </td>
                </tr>
                <tr>
                    <td>
                        Channel number:
                    </td>
                    <td>
                        <input id="channelNumber" type="text" />
                    </td>
                </tr>
            </table>
            <br />
            <input type="button" onClick="captureVigraImage()"
value="Capture" />
        </form>
        <img id="imageCapture2" src="javascript:void(0);"/>

I know that the callback from the Java method is being called, as I see
"callback function" displayed on the page from the innerHTML call. Is
there something I am missing from the examples in the .war file? Is
there anything else I need to do? I know the image isn't an empty image
or a 0x0 image or anything like that. I must be missing something, but I
cannot figure it out.

If anyone has any suggestions I will appreciate them greatly.

Thanks,
Dan
