AjaxFileUpload problem in deployment

I have an AjaxFileUpload on a page that works fine in development but not in deployment. When I upload a file I get an UnknownKeyException on the AjaxProgressBar inside the AjaxFileUpload ??

My bindings are

UploadPicture: AjaxFileUpload {

data = uploadedFile;

filePath = fileName;

succeededAction = savePhoto;

uploadLabel = "Upload photo";

finishedFunction = "img_previewUpdate();";

progressBarBeforeStart = true;

refreshTime = 1000;

}

This is the stack trace:

"URL" = "/cgi-bin/WebObjects/MyApp.woa/4/ajax/6.0.9.1.2.9?_u=_0ProgressBar&1324052204904";

}

com.webobjects.foundation.NSKeyValueCoding$UnknownKeyException: [<er.ajax.AjaxProgressBar name: er.ajax.AjaxProgressBar subcomponents: null > valueForKey()]: lookup of unknown key: 'uploadFormID'.

The WOComponent er.ajax.AjaxProgressBar does not have an instance variable of the name uploadFormID or _uploadFormID, nor a method of the name uploadFormID, _uploadFormID, getUploadFormID, or _getUploadFormID

This is what the generated HTML looks like (I took out some whitespace):

<iframe name="_0UploadFrame" src="" width="0" height="0" border="0" style="border: none;"></iframe>

<form name="_0Form" enctype="multipart/form-data" method="post" target="_0UploadFrame" action="">
	<input name="wosid" type="hidden" value="7f5NZMw8JeYq0B8lMUh6tw" />
	<input name="id" type="hidden" value="_0" />
	<table>
		<tr class="upload_row">
			<td class="input_col"><input name="uploadedFile" type="file" /></td>
			<td class="action_col"><input  type="button"  value="Upload photo"></input></td>
		</tr>

		<tr class="progress_row">
			<td colspan = "2">
				<div  id="_0ProgressBar" updateUrl="/cgi-bin/WebObjects/MyApp.woa/ajax/6.0.9.3.5.2.9">
</div><script>AUC.register('_0ProgressBar');</script>
			</td>
		</tr>
	</table>
</form>

I've used this many times before, and everything is fine. Heck, it's fine in development. Everything else works fine in deployment. I'm on EC2 btw with 5.4.3. It's like the context for the ERXWOForm puts it inside the AjaxProgressBar when it should be inside the AjaxFileUpload. ??? I use other Ajax stuff all over and it is fine, so I don't think it is a problem with the handler or something bigger.

Thanks for any help,

John
