Hi all,

There is a peculiar problem that i m facing with file upload. There is an inputfile on my VF and whenever i refresh the page, the file value is getting lost. I want to retain the file uploaded even when the page is refershed.

code:

VF:

<apex:inputFile value="{!attachment.body}"/>

Apex Class:

public Attachment attachment{
    get {
      if (attachment== null){
        attachment= new Attachment();
         doclist.add(attachment);}
      return attachment;
    }
    set;
  
  }

Thanks,

Sandeep
