rich:fileUpload more file information - jsf

Question

I want to upload many files and I have chosen rich:fileUpload control for this.
My problem is that I need to add more information for each file, for example the title I want to appear in the application for that file. How can I do that, and send to the fileUploadListener method in order to use the id?

Based in your question, the RichFaces FileUpload demo has all the info you need to handle file upload for 1 or more files at the same time.
If you want to add more data (like h:inputText values and others), then you should pass them using valueChangeListener instead value tag attribute, because the fileUploadListener is an event that happens within an ajax call, so your UIComponents won't call the setters for the attributes.
Some code to explain the behavior:
<h:panelGrid cols="2">
<h:outputText value="File Title:">
<h:inputText value="#{fileBean.fileTitle}" immediate="false"
valueChangeListener="#{fileBean.valueChangeFileTitle}" />
<h:outputText value="File:">
<rich:fileUpload
fileUploadListener="#{bean.fileUpload}">
</rich:fileUpload>
</h:panelGrid>
The Bean to handle the requests
public class Bean {
private String fileTitle;
public Bean() {
}
//getters and setters...
public String getFileTitle() {
return this.fileTitle;
}
public void setFileTitle(String fileTitle) {
System.out.println("Calling the setter");
this.fileTitle = fileTitle;
}
public void valueChangeFileTitle(ValueChangeEvent e) {
System.out.println("Calling the ValueChangeListener");
fileTitle = (String)e.getNewValue();
}
//this will be invoked by an ajax call
//the setter of the view won't be invoked for fileTitle
//instead, we should take its value using valueChangeListener
public void fileUpload(UploadEvent ue) {
MyFileManager mfm = MyFileManager.getFileManager();
MyFile myFile = new MyFile();
myFile.setTitle(this.fileTitle);
myFile.setName(ue.getUploadItem().getFileName());
myFile.setData(ue.getUploadItem().getData());
mfm.createFile(myFile);
}
}
Also, avoid to use System.out.println calls in your code, I'm doing it so you can understand what method will be called, instead use a Logger like Log4j.
