[Wicket-user] dynamically populate tree
Hello world I have a problem with a data tree: I need to generate a data tree that shows the structure of products' classification from this table: Object: ClasseCND id| anno | livello | descrizione | classemadre| A| 2005 |0| d | null | A01| 2005 |1| g | A| B| 2005 |0| gg | null | B01| 2005 |1| g | B| B02| 2005 |1| g | B| etc... I have more levels of depth in the tree...and I have a great number of classes to show At first time I would show to the user only the level 0 of my data structure and, when the user select one node of the tree, I would show the requested subtree expanded. There is a way to do something like that without generate and cache all the classification tree in the session ? Some way to dynamically populate the tree when the user select the node he wants to see expanded ? Any suggest will be appreciate Thanks in advance Galbu -- View this message in context: http://www.nabble.com/dynamically-populate-tree-tf3758317.html#a10622286 Sent from the Wicket - User mailing list archive at Nabble.com. - This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.

Re: [Wicket-user] Send files with Wicket
Hi Nino thanks for interesting in my problem... I try to explain better what I need: I'm developing an application that allows to upload some report files in a db so I want to create a page like a ChooseFile in which there is a form with a button Browse that shows (on click) the folders' tree to the user and allows him to have the correct localization path of the file he wants to write on the db. I think it's a standard function for a web application, but I have not any example to do something like that with Wicket... I hope it's more clear Thanks in advance Galbu Nino Saturnino Martinez Vazquez Wael wrote: Hi Galbu Could you rephraise your question, please?

Re: [Wicket-user] Send files with Wicket
Hi Johan thanks for the example it's what I need, but I have another
question...
I'm trying to use FileUploadField Component and I have a problem: I want to
select a file with my ChooseFile page and then send it to another page
called UpdateProdotti in which I have a confirm button to press for write
the file on db.
But when I read the file selected in the ChooseFile page I lost the
information on the location path so, when the UpdateProdotti (File
uploadFile) is invoked, I can't find the file (no path is present).
I send the source code of ChooseFile, UpdateProdotti pages to be more
clear...if someone could show me where I'm wrong...
Thanks in advance Galbu
public class ChooseFile extends ConsumiTemplateMenuPage {
public ChooseFile() {
super();
verifyAccess();
final FeedbackPanel feedback = new FeedbackPanel(feedback);
final FileUploadForm form = new
FileUploadForm(chooseFileForm);
add(feedback);
add(form);
}
public String getPageTitle() {
return Scelta File da Salvare;
}
private class FileUploadForm extends Form {
private File uploadFile;
private FileUploadField fileUploadField;
public FileUploadForm(String name) {
super(name);
// set this form to multipart mode (allways needed for
uploads!)
setMultiPart(true);
// Add one file input field
add(fileUploadField = new FileUploadField(fileInput));
// Set maximum size to 100K for demo purposes
//setMaxSize(Bytes.kilobytes(100));
}
public void onSubmit() {
final FileUpload upload =
fileUploadField.getFileUpload();
if (upload != null) {
uploadFile = new
File(upload.getClientFileName());
setResponsePage(new UpdateProdotti(uploadFile));
}
}
}

Hello world I'm a beginner in wicket developing and I need just a little help: I'm studying Wicket on Pro Wicket by Karthik Gurumurthy and I have a problem with the BookStore example because the pdf version of the book is incomplete . . .

I can't find the correct pdf version of Pro Wicket so if anybody has used this tutorial and could show me these pages I'll be grate . . .
