> add support to uploading to a resource
> --------------------------------------
>
> Key: WICKET-7033
> URL: https://issues.apache.org/jira/browse/WICKET-7033
> Project: Wicket
> Issue Type: New Feature
> Components: wicket
> Reporter: Ernesto Reinaldo Barreiro
> Assignee: Ernesto Reinaldo Barreiro
> Priority: Major
> Fix For: 10.0.0, 9.14.0
>
>
> Add support for the following:
> * Upload to a resource in an asynchronous non page blocking request
> * Add an optional way to block the user from leaving the page while the
> upload is happening
> * Ways to cancel the upload
> * Adapt the upload progress bar to work with this new "component" and improve
> its code as in some corner cases it is producing client side errors (I
> created an issue for that some time ago).
> * Maybe useful too: create a web socket based progress bar, as the upload
> progress bar now works pulling the server every second.
> * Also to add an example to wicket-examples that uses a smart JS uploader,
> like in the blog
> (https://github.com/martin-g/blogs/blob/master/file-upload/). This way you
> will verify that the new APIs are easily extendable.
