Hallo,
I would like to achieve following functionality, how is it possible?
I have an abstract panel with upload field in it.
The panel is to be used as a form component.
In the panel there is an abstract method
processFile(FileUpload fileUpload)
which I would like to get called everytime a form gets submitted, so I
would just add the element, fill the method and done.
At first I thought that it would work by letting panel implement
IFormSubmitListener and in panel implement interface method this way:
onFormSubmitted() {
processFile(uploadField.getFileUpload());
}
But it does not work this way.
I am using this panel in a wizard, which has already its own Form, so I
cannot override onSubmit method of this form and I do not want to alter
much code, I thought that this would be an elegant way how to do it.
Is there any other way how to do it? Or do you have some reading where
can I find beside studying the code, which is a bit difficult for me at
this time?
Thank you.
Vitek
