URL: https://issues.apache.org/jira/browse/WICKET-6414
Project: Wicket
Issue Type: Bug
Components: wicket
Affects Versions: 7.6.0, 7.5.0
Environment: JBoss EAP 6.4
Reporter: Matías Fernández
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.
{code:java}
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);
{code}
The problem is after download if we want to export again or change any
component which access model object throw this exception.
