[CLOSED] 1.2.4 FileUploadField on IE and duplicate name

[pepez]

The request is parsed using org.apache.commons.fileupload.servlet.ServletFileUpload parseRequest.

On IE 6 & IE 7 file upload request contains two fields with same name for FileUploadField. On FF3 or Safari the upload works fine and no duplicate elements are found in the request.

Anyone else with the same problem? Or am I using file upload somehow in a wrong way?

I don't have it, and I use the upload widget a lot. I use IE6 and I don't have any trouble so far.

If you don't put some source code so I can compare I can't tell you what's wrong. I use common-fileupload.jar in the server too.

test case:

package ccc.contentcreator.client;

import com.extjs.gxt.ui.client.event.ButtonEvent;
import com.extjs.gxt.ui.client.event.SelectionListener;
import com.extjs.gxt.ui.client.widget.Window;
import com.extjs.gxt.ui.client.widget.button.Button;
import com.extjs.gxt.ui.client.widget.form.FileUploadField;
import com.extjs.gxt.ui.client.widget.form.FormPanel;
import com.extjs.gxt.ui.client.widget.form.TextField;
import com.extjs.gxt.ui.client.widget.layout.FitLayout;
import com.extjs.gxt.ui.client.widget.layout.FormData;
import com.google.gwt.core.client.EntryPoint;


/**
 * Entry point classes define <code>onModuleLoad()</code>.
 */
public final class ContentCreator implements EntryPoint {

    private final FormPanel panel = new FormPanel();

    public void onModuleLoad() {

        Window w = new Window();
        w.setWidth(640);
        w.setHeight(480);
        w.setLayout(new FitLayout());
        w.setBodyStyle("backgroundColor: white;");
        w.setMaximizable(true);
        w.show();

        panel.setAction("upload");
        panel.setEncoding(FormPanel.Encoding.MULTIPART);
        panel.setMethod(FormPanel.Method.POST);

        TextField<String>   description = new TextField<String>();
        description.setName("description");
        description.setFieldLabel("description");
        panel.add(description);

        FileUploadField     file = new FileUploadField();
        file.setName("fileField");
        file.setFieldLabel("file");
        panel.add(file);

        panel.addButton(new Button(
            "submit",
            saveAction()));

        w.add(panel);

    }
    private SelectionListener<ButtonEvent> saveAction() {
        return new SelectionListener<ButtonEvent>() {
            @Override
            public void componentSelected(final ButtonEvent ce) {
                panel.submit();
            }
        };
    }
}

Ah, nothing to do with GXT. Our file handling was not handling form properly.

Calling org.apache.commons.fileupload.FileItem.isFormField() helps...

the same problem happens to me, does anyone know how to solve this?
