I am no really sure if this is a bug, but I have encoutered a problem with my registration page when I tried to add FileEntry component there. When I send the data through h:commandButton to the bean it converts Strings into bad format (for example "Někdo" into "NÄ›kdo"). Everything is working ok without fileEntry. I also enclose some source codes. So now I have separeted it into two pages - one for data and second one for files, but I would rather have it on a single page.
This is my fileEntry component on a page
#{registerPage.photo}: <ace:fileEntry absolutePath="C:/uploaded/" maxFileCount="1"
                                          label="File Upload"
                                          fileEntryListener="#{registration.fileListener}"
                                          useOriginalFilename="true"
                                          immediate="true"
                                          id="photo"/>]
and this the file listener in bean
 public void fileListener(FileEntryEvent event) {
        FileEntry fileEntry = (FileEntry) event.getSource();
        String id = fileEntry.getId();
        FileEntryResults results = fileEntry.getResults();
        for (FileEntryResults.FileInfo fileInfo : results.getFiles()) {
            if (fileInfo.isSaved()) {
                  setPhoto(fileInfo.getFile().getPath());
            }
}
The listener, getters and setters for data and action method is all in the same bean (registration)
