DownloadLink problem

2010-03-02 Thread Martin Asenov 
Hi, guys!

I experience some DownloadLink problem - I have these fields:

File linkModel;
DownloadLink theLink = new DownloadLink(link_id, new ModelFile(linkModel));
theLink.setOutputMarkupId(true);

After another button click I have the linkModel field pointing to real file on 
the file system. And then I say:

target.addComponent(theLink);

the link name is still invisible, and when I click on the small clickable area, 
Wicket comes up with:

WicketMessage: Method onLinkClicked of interface 
org.apache.wicket.markup.html.link.ILinkListener targeted at component 
[MarkupContainer [Component id = exported_file_link]] threw an exception

Root cause:

java.lang.IllegalStateException: 
org.apache.wicket.markup.html.link.DownloadLink failed to retrieve a File 
object from model
 at 
org.apache.wicket.markup.html.link.DownloadLink.onClick(DownloadLink.java:141)
 at org.apache.wicket.markup.html.link.Link.onLinkClicked(Link.java:224)
 at java.lang.reflect.Method.invoke(Method.java:597)
I thought I've made everything perfect, but it seems that I haven't.
Any help is appreciated!

Best regards,
Martin

Not sure... but could you try something like:

DownloadLink downloadLink = new DownloadLink(link_id, new
AbstractReadOnlyModelFile(){
public File getObject() {
return this.linkModel;
};
},myfile.xxx);
downloadLink.setOutputMarkupId(true);

and make linkModel a member variable? This way file will be refreshed.

Best,

Weird. Just try this example:

import java.io.File;

import org.apache.wicket.ajax.AjaxRequestTarget;
import org.apache.wicket.ajax.markup.html.AjaxLink;
import org.apache.wicket.markup.html.link.DownloadLink;
import org.apache.wicket.markup.html.panel.Panel;
import org.apache.wicket.model.AbstractReadOnlyModel;

/**

 */
public class TestDownLoadLink extends Panel {


private static final long serialVersionUID = 1L;

private File test = null;

private DownloadLink download;
/**
 * @param id
 */
public TestDownLoadLink(String id) {
super(id);

this.download = new DownloadLink(download, new
AbstractReadOnlyModelFile(){

 private static final long
serialVersionUID = 1L;

@Override
public File getObject() {
return test;
}

 },TestDownLoadLink.html) {

private static final long serialVersionUID = 1L;

@Override
public boolean isEnabled() {

return test != null;
}
 };
 download.setOutputMarkupId(true);
 add(download);

 AjaxLinkVoid update = new AjaxLinkVoid(update) {

private static final long serialVersionUID = 1L;

@Override
public void onClick(AjaxRequestTarget target) {
test = new
File(TestDownLoadLink.class.getResource(TestDownLoadLink.html).getFile());
if(target != null) {
target.addComponent(TestDownLoadLink.this.download);
}
}
 };

 add(update);
}
}

and the HTML

html xmlns:wicket=org.apache.wicket
head
/head
body
wicket:panel
a wicket:id=downloaddownload/a
a wicket:id=updateClick me to update download/a
/wicket:panel

/html

Just place them somewhere and do

new TestDownLoadLink(xxx);

It works for me. First time the download link is disable and when you click
on the AJAX link file is assigned, link is refreshed and you can download
your file;-)

But I want to have the link invisible on startup (because the file's empty). So 
I have this: (doesn't work, but has to)

exportedFileLink = new DownloadLink(exported_file_link, new 
LoadableDetachableModelFile() {

  private static final long serialVersionUID = 1L;

  @Override
  protected File load() {
return exportedFile;
  }
}, PhonebookExporter.OUTPUT_FILE_NAME) {

  private static final long serialVersionUID = 1L;

  @Override
  public boolean isVisible() {
return exportedFile != null;
  }
};
final WebMarkupContainer exportedFileLinkHolder = new 
WebMarkupContainer(link_holder);
exportedFileLinkHolder.setOutputMarkupId(true);
exportedFileLinkHolder.add(exportedFileLink);

rightForm.add(exportedFileLinkHolder);
rightForm.add(new AjaxButton(export_button) {

  private static final long serialVersionUID = 1L;

  @Override
  protected void onSubmit(AjaxRequestTarget target, Form? form) {

PhonebookExporter exporter = getExporter();
exportedFile = exporter.export(uploadFolder);

if (exportedFile == null) {
  error(getString(not_exported));
} else {

Oh my God!!! The problem was that the button that is supposed to do the export

rightForm.add(exportedFileLinkHolder);
rightForm.add(new AjaxButton(export_button) {

});

 I really start to get pissed off by this one!!! g

 Weird. Just try this example:

 import java.io.File;

 import org.apache.wicket.ajax.AjaxRequestTarget;
 import org.apache.wicket.ajax.markup.html.AjaxLink;
 import org.apache.wicket.markup.html.link.DownloadLink;
 import org.apache.wicket.markup.html.panel.Panel;
 import org.apache.wicket.model.AbstractReadOnlyModel;

 /**
  * @author Ernesto Reinaldo Barreiro (reier...@gmail.com)
  *
  */
 public class TestDownLoadLink extends Panel {


private static final long serialVersionUID = 1L;

private File test = null;

private DownloadLink download;
/**
 * @param id
 */
public TestDownLoadLink(String id) {
super(id);

this.download = new DownloadLink(download, new
 AbstractReadOnlyModelFile(){

 private static final long
 serialVersionUID = 1L;

@Override
public File getObject() {
return test;
}

 },TestDownLoadLink.html) {

private static final long serialVersionUID = 1L;

@Override
public boolean isEnabled() {

return test != null;
}
 };
 download.setOutputMarkupId(true);
 add(download);

 AjaxLinkVoid update = new AjaxLinkVoid(update) {

private static final long serialVersionUID = 1L;

@Override
public void onClick(AjaxRequestTarget target) {
test = new

 File(TestDownLoadLink.class.getResource(TestDownLoadLink.html).getFile());
if(target != null) {
target.addComponent(TestDownLoadLink.this.download);
}
}
 };

 add(update);
}
 }

 and the HTML

 html xmlns:wicket=org.apache.wicket
 head
 /head
 body
 wicket:panel
 a wicket:id=downloaddownload/a
 a wicket:id=updateClick me to update download/a
 /wicket:panel
 /body
 /html

 Just place them somewhere and do

 new TestDownLoadLink(xxx);

 It works for me. First time the download link is disable and when you click
 on the AJAX link file is assigned, link is refreshed and you can download
 your file;-)

 Best,

 Ernesto
