Hi,
I have been trying to get a local file upload to work in a tab panel.
It works fine in Firefox using a vanilla servlet on the backend, but
in Safari, when I click the button to submit, it freezes every time.
The structure of my page is a little unique, so I will describe it.
I have my entry point class which has a DockPanel as the RootPanel. In
the CENTER of the DockPanel I have my own class called UploadPanel
which extends DockPanel. On there, in the EAST, I have a TabPanel
(with three tabs, the second of which contains my class
UploadFileForm). Also in the UploadPanel I have a button which has my
ClickListener.
The UploadFileForm extends FormPanel and here is the header and
constructor:
public class UploadFileForm extends FormPanel{
private VerticalPanel mainPanel = new VerticalPanel();;
private Label fileLabel = new Label("Please choose the location of
the local file you wish to upload.");
private RadioButtonPanel radioButtonPanel = new RadioButtonPanel();
private FileUpload uploadField = new FileUpload();
private MetadataPanel hiddenMetadataPanel;
private Document document;
public UploadFileForm(){
this.setAction(GWT.getModuleBaseURL() + "upload");
this.setEncoding(FormPanel.ENCODING_MULTIPART);
this.setMethod(FormPanel.METHOD_POST);
this.setWidget(mainPanel);
mainPanel.add(fileLabel);
uploadField.setName("uploadFormElement");
mainPanel.add(uploadField);
mainPanel.add(radioButtonPanel);
UploadSubmitHandler uploadSubmitHandler = new
UploadSubmitHandler();
this.addSubmitHandler(uploadSubmitHandler);
UploadCompleteHandler uploadCompleteHandler = new
UploadCompleteHandler();
this.addSubmitCompleteHandler(uploadCompleteHandler);
}
...
}
onClick in the uploadPanel, I check what Tab is selected, and if its
the one with the UploadFileForm, I do:
uploadFileForm.submit();
which breaks Safari every time without showing me any information
about exceptions (Safari crashes).
I follow the template here:
http://www.jroller.com/hasant/entry/fileupload_with_gwt
pretty much exactly except for my unique class structure.
Does anyone have any idea what might be going wrong here?
Thanks so much,
Greg
