Juraj Húska commented on RF-13514:
----------------------------------
# {{maxFilesQuantity}} - for me it is the other way round, attribute works correctly when
adding files with D&D, it does not work when adding files manually. The add button
does not disappear nor there is any other restriction to upload more files.
# {{keydown}} - IMHO it should be fired when a user has focus on {{fileUpload}} component
and press key (without further releasing). Other key related handlers do not work as well
({{onkeyup}}, {{onkeypress}})
Support file upload progress tracking in Servlets >= 3.0
environment

Key: RF-13514
URL:
https://issues.jboss.org/browse/RF-13514
Project: RichFaces
Issue Type: Enhancement
Security Level: Public(Everyone can see)
Components: component-input, core
Affects Versions: 5.0.0.Alpha3
Reporter: Lukáš Fryč
Assignee: Michal Petrov
Fix For: 4.5.0.Alpha3
We currently support two approaches for file upload:
* Servlets 2.5: own request form data parser
[{{MultipartRequestParser}}|https://github.com/richfaces/richfaces/blob/master/framework/src/main/java/org/richfaces/request/MultipartRequestParser.java]
* Servlets 3.0: leveraging {{HttpServletRequest#getParts()}}
However as we have discussed RF-13444, we had to finally do a trade-off of limiting
support of file progress tracking. I.e. in Servlets 3.0 we have no simple way how to track
file upload progress since getParts() returns data for completed request.
There are several possible outcomes:
1) drop server-side file upload progress tracking and leverage XHR2/HTML5 that has
built-in ability to track progress
* imho we are already prepared to switch to XHR2 and client-side progress (possibly
leveraging some third-party widget) since [all major browsers support it at least one
version
back|http://caniuse.com/#feat=xhr2]
* existing implementation:
http://www.script-tutorials.com/pure-html5-file-upload/
2) use a {{ServletFilter}} to wrap a request as our {{FileUploadFacesContextFactory}}
currently do and so have an earlier access to the request object
* this principle has a drawback - we have to ensure our filter has high-enough priority
so the servlet container won't touch the request body yet
