Hi Frank,
The multiFileUpload uses a collection to store the uploaded files.
If you want to have N number of MultiFileUpload then u need N number of
collections. So basiclly u need a collection of collection. The first
one is to represent each multiFileUpload component and the the second is
to hold the uploaded files. Have a look at the sample code.
fBeans is a list of fbean, which store the description of the file, the
number of copies, and the collection where the files will be store.
setModel(new CompoundPropertyModel(fBeans));
ListView view = new ListView("fileViewList", fBeans)
{
protected void populateItem(ListItem item) {
Fbean f = (Fbean) item.getModelObject();
item.add(new Label("desc", f.getDesc()+" : "));
item.add(new MultiFileUploadField("fileInput", new
PropertyModel((Fbean) item.getModelObject(), "uploads"), f.getCopies()));
}
};
Regards,
Al Shamsi

Dear Friends,
I am having a problem with putting MultiFileUploadField inside a
ListView. I am following the example, but somehow the uploads collection
is not getting populated with the files. However when I directly add the
MultiFileUploadField on a form everything seems to work. Could someone
please shed some light on this.
Here is some code snippet
List ls = Arrays.asList(new String[]{"Passport "});
ListView pl = new ListView("plist",ls)
{
protected void populateItem(ListItem arg0) {
MultiFileUploadField ff=new
MultiFileUploadField("file_input",new
PropertyModel(this,"uploads"),3);
fileUploadList.add(ff);
fileUpload.add(ff);
arg0.add(ff);
}
};
And the listview is on a form and the collections(uploads) is on the form
to just as in the example. I am sure its something with the component
hierarchy. But not sure how to call the uploads correctly. I think there
is something wrong with the expression.
Thanks,
Franklin
