Log:
Applied fix from trunk for revision: 1858035
===

Fixed: Parameters are not available to the next response type when form of enctype=multipart/form-data type is submitted
(OFBIZ-10833)

Reason: The UtilHttp.getMultiPartParameterMap method is used to get the parameters in case of multipart/form-data type.
The getMultiPartParameterMap parse the request to get the parameters.

{code}
uploadedItems = UtilGenerics.<FileItem>checkList(upload.parseRequest(request));
{code}

As per the Apache commons-fileupload guideline, a request can only be parsed once [1]. So, for the next response, again the same getMultiPartParameterMap method is executed (with the same request object), and no parameters are found, since, the request is already parsed.

Also, have a look at the StackOverflow question [2], it also contains related information.

Fix for the issue:
Set the consumed parameters (except uploaded file(s)) in the request attribute so that it will be available to the next response.
The uploaded file(s) are not set in request attribute again to avoid unnecessary memory consumption, also it makes no sense to traverse the uploaded file in the request.

Thanks: Ingo Wolfmayr for reporting issue and Jacques Le Roux for review.
