Richfaces 4, JSF2, Fileupload render Problem
hello,
I am currenctly develop a fileupload which works quite fine. I can upload and process my files perfectly, but i am missing the refresh which was shown in the showcase.
In my file processing exception can occour in the business logic and i would like to have them displayed in the interface. I tried many things, but couldn't get it to work.
I also tried the showcase where the refreshing worked fine. It shows the newly uploaded files as expected. If i change the scope from session to view the refresh doesn't happen anymore. Is session scope required?
Is it possible at all to refresh the <h:messages errorStyle="color:red" warnStyle="color: yellow" /> element this way?
greetings
max
My Bean:
@ManagedBean
@ViewScoped
public class FileUpload implements Serializable {
public void uploadSvg(FileUploadEvent event) {
UploadedFile uploadedFile = event.getUploadedFile();
File file = writeFileToDisk(uploadedFile);
try {
Utils.getSpringBean(FigureService.class).importFigure(
file.getAbsolutePath());
} catch (Exception e) {
FacesMessage message = new FacesMessage(FacesMessage.SEVERITY_ERROR,
file.getName() + " -> " + e.getMessage(), null);
FacesContext.getCurrentInstance().addMessage(null, message);
log.error(e,e);
// TODO why does this not show up in the frontend???
}
}
