Processing uploaded file in ViewModel

Hi, I'm trying to upload a file from client and process it in the ViewModel.

zul file:

<button label="Upload file" upload="true" onClick="@command('importTexts')" />

view model:

@Command
@NotifyChange("importedTexts")
public void importTexts()
{
    Media media = Fileupload.get();

    if ( media == null)
    {
        Messagebox.show("No file selected", "Error", Messagebox.OK, Messagebox.ERROR);
        return;
    }
}

The problem is that command importTexts() gets executed immediately after I click the upload button, and before the actual file selection. Therefore Fileupload.get() returns null. I also tried using <fileupload> with the same result:

<fileupload label="Upload file">
    <attribute name="onUpload">vm.importTexts();</attribute>
</fileupload>

What is the right way to do this? I don't want any logic in my zul file. Thanks for your advice.

After some experimenting I've done it like this:

zul file:

<fileupload label="Upload file" onUpload="@command('importTexts',media=event.media)" />

view model:

@Command
@NotifyChange("importedTexts")
public void importTexts(@BindingParam("media") Media media)
{
    ...
}

But thanks for your answer anyway.
