Leonardo Uribe commented on TOMAHAWK-1381:
------------------------------------------

Updated patch. To solve this point:

- MultipartRequestWrapper calls FileUploads setSizeMax, this is the size for 
the total upload, and not individual files, it should call setFileSizeMax 

It was created a param called uploadMaxSize that it is tied to 
FileUpload.setSizeMax, so uploadMaxFileSize is tied to 
FileUpload.setFileSizeMax. If uploadMaxSize(or 
org.apache.myfaces.UPLOAD_MAX_SIZE in TomahawkFacesContextWrapper case) is not 
set, the default value is the value initialized on uploadMaxFileSize.



> HtmlInputFileUpload does not fail gracefully when filesize exceeds 
> uploadMaxFileSize web.xml value

> When uploading a file using the HtmlInputFileUpload that exceeds that 
> uploadMaxFileSize web.xml setting the system fails without error and no form 
> data is not processed by JSF.
> I think that there are a number of reasons for this:
> - There is a bug in commons-fileupload that prevents failures from being 
> handled correctly (see FILEUPLOAD-169)
> - MultipartRequestWrapper calls FileUploads setSizeMax, this is the size for 
> the total upload, and not individual files, it should call setFileSizeMax
> - HtmlFileUploadRenderer calls fileUpload.parseRequest(request), this will 
> fail if any size exceptions are thrown, it would be better to use 
> fileUpload.getItemIterator and catch each exception.
