Description

Hello there Wicket Developers!

We are currently working with Wicket 7.4 and have the following behavior.

We have a form to download some report after fill some fields. This button and the fields are inside a Wicket Form.

To do this we have a on submit this code.

final AbstractResourceStreamWriter rstream = new AbstractResourceStreamWriter() {
            @Override
            public void write(final OutputStream output) throws IOException {
                output.write(bytes);
            }

            @Override
            public String getContentType() {
                return contentType;
            }
        };

        final ResourceStreamRequestHandler handler = new ResourceStreamRequestHandler(rstream)
                .setFileName(downloadFileName)
                .setCacheDuration(Duration.NONE)
                .setContentDisposition(ContentDisposition.ATTACHMENT);
        RequestCycle.get().scheduleRequestHandlerAfterCurrent(handler);

The problem is after download if we want to export again or change any component which access model object throw this exception.
