inputText not Updating in Backing Bean

[amattas]

I'm trying to upload a file and pull data in from a description field when the listener processes the request. Here is the applicable code, however the description always ends up being null in the database.

 <h:form enctype="multipart/form-data" id="upload">
 <h:panelGrid columns="2">
 <h:outputText value="Description: " id="description" />
 <h:inputText value="#{OrderView.uploadDescription}" id="uploadDescription" immediate="true" >
 <a4j:support event="onkeyup" reRender="upload" />
 </h:inputText>
 </h:panelGrid>
 <rich:fileUpload id="upload"
 immediateUpload="true" fileUploadListener="#{OrderView.addUpload}"
 disabled="#{fn:length(OrderView.uploadDescription) lt 10}">
 </rich:fileUpload>
 <span id="submitbutton"><h:commandButton value="Done"
 action="success" styleClass="button" /> </span>
 </h:form>

 public void addUpload(UploadEvent event) {
 if (event == null) { _logger.warning("null upload event"); }
 UploadItem uploadItem = event.getUploadItem();
 FileInputStream inputStream;
 FileOutputStream outputStream;
 FacesContext facesContext = FacesContext.getCurrentInstance();
 ExternalContext externalContext = facesContext.getExternalContext();
 String username = externalContext.getUserPrincipal().getName();
 String filename = Long.toString(new Date().getTime());
 String extension = fileExtension(uploadItem.getFileName());
 String uploadLocation = this.getUploadParent() + '/' + this.getUploadSuffix() + '/';
 File outputDir = new File(uploadLocation);
 if (!outputDir.exists()) outputDir.mkdirs();
 try {
 System.out.println(uploadLocation + filename + extension);
 outputStream = new FileOutputStream(uploadLocation + filename + extension);
 if (uploadItem.isFile()) {
 inputStream = new FileInputStream(uploadItem.getFile());
 outputStream.getChannel().transferFrom(inputStream.getChannel(), 0, inputStream.getChannel().size());
 inputStream.close();
 } else
 outputStream.write(uploadItem.getData());
 outputStream.close();
 setters.addFile(this.getId(), filename+extension, this.getUploadDescription(), username);
 } catch (FileNotFoundException e) {
 _logger.severe("input file not found");
 } catch (IOException e) {
 _logger.severe("can't write output file");
 } catch (UnknownUserException e) {
 _logger.severe("upload user does not exist");
 } catch (UnknownOrderException e) {
 _logger.info("upload order does not exist");
 }


 }

Hi,

I tried your code. It works fine for me using 3.2.1 RF.
Description is NOT null in uploadListener. 'OrderView' bean is session scoped in my case.

Anyway, I cannot understand why do you force AJAX request after every 'onkeyup' event.

There is more convenient way to enable fileUpload component after 10 character were entered in description field: please use JS API.

It should be like this:

<h:inputText id='descriptionID' onkeyup='return enableFileUpload(this)' .../>

<script>
function enableFileUpload (elt) {
 if (elt.value && elt.value.length >= 10) {
 $('fileUploadID').component.enable();
 }
return true;
}
</script>

Please see documentation for more detailed info about JS API.

Is it possible to do this in a request scoped bean?

I've run into an issue using a4j:keepAlive that breaks it because of some objects needed for my persistance layer to function properly aren't serializable, so I don't think I can do it this way.

May be this will help?
