MultiFileItem in LGPL

[Oleg]

Hi

I have read
https://www.smartclient.com/smartgwt...cs/Upload.html
and
https://www.smartclient.com/smartgwt...iFileItem.html

When I push Save button on picker a MultiFileItem sends in add request file name istead of file itself like described in MultiFileItem JavaDoc.
Could you please explain why?

DataSource ds = DSFactory.INSTANCE.getNewDS(KNOWLEDGEFILE);
ds.getField(IDKNOWLEDGE).setForeignKey(IDKNOWLEDGE);
MultiFileItem multiFileItem = new MultiFileItem(ConstDBField.KNOWLEDGEFILE);
multiFileItem.setAttribute("dataSource", ds.getID());
