FileUpload dialog

[GoogleCodeExporter]

How can we replace file upload dialog from GWT-EXT? What is the analogue
in SmartGWT? This is a missing feature which adds to migration pains from 
GWT-EXT.

Thanks,

I tried to use it but it doesn't work in hosted mode and with Internet 
Explorer. the iframe onload function is not called. It works only with 
firefoxe. Can you please 
tell me how can I make it work ?

For IE support

In your gwt.xml you need to set:
<replace-with class="at.bestsolution.gwt.util.impl.DynamicCallbackFormImpl">
        <when-type-is class="at.bestsolution.gwt.util.impl.DynamicCallbackFormImpl"/>
    </replace-with>

    <replace-with class="at.bestsolution.gwt.util.impl.DynamicCallbackFormImplIE6">
        <when-type-is class="at.bestsolution.gwt.util.impl.DynamicCallbackFormImpl"/>
        <when-property-is name="user.agent" value="ie6"/>
    </replace-with>

I had made one which works almost the same as the File Dialog in GWT-Ext-UX. 

Sanjiv: can you let me join to smartgwt-extensions project? So I can upload it 
there.

I'm looking forward to this as well.  Has there been any progress since the 
last 
comments on this issue?  I noticed it mentioned on the smartgwt extensions page 
but 
haven't seen a release.  I'd certainly be willing to test this out.

Any progress on this implementation?

Need this functionality. Can someone upload it so that all of us dont have to 
reinvent it? This will help out a great bit.

praseedt, 
Pete also posted the required code here :
http://forums.smartclient.com/showthread.php?t=5477

Users have used it successfully.

This will be incorporated into the smartgwt-extensions project but until then it
should be fairly straightforward to incorporate the code into your project.

Hi all,

When following these links I find there are at least three suggested 
approaches/code 
samples (see list below) with differing degrees of complexity.

Is there a best of breed solution for file upload that works across browsers?

It seems plain GWT has FormPanel and FormHandler, the latter containing support 
for 
intercepting the submit complete event and providing access to the response 
content.

http://google-web-
toolkit.googlecode.com/svn/javadoc/1.5/com/google/gwt/user/client/ui/FormHandler
.html

I haven't tried this stuff, but is there any plan/merit introducing something 
similar on DynamicForm - would this avoid provide the solution we're all 
looking for?

@tomsontom

I have a question concerning the IE6 implementation. In the unhookevents 
function you
set form.onsubmit = null. But when I destroy the window I get javascript errors 
that
"form" doesn't exist. Can I safely delete that line? Or did I mess something up 
that
the form can't be found?

Can someone provide an example on how to use the DynamicCallbackForm? Thanks!

I tried the following but the onSubmitComplete doesn't seem to get called:

display.getUploadForm().addFormHandler(new DynamicFormHandler() {
      public void onSubmitComplete(DynamicFormSubmitCompleteEvent event) {
        System.out.println("submit complete");
        String responseString = event.getResults();
        System.out.println("Response String is " + responseString);
      }
    });

// Handler for import button
    display.getImportButton().addClickHandler(new ClickHandler() {

      public void onClick(ClickEvent event) {
        if (display.getUploadForm().validate()
            && display.getImportForm().validate()) {

        // set value for the hidden field
        display.getUploadForm().setValue(
              ModelConstants.FILE_DS_FILE_ID,
              (String) display.getImportForm().getValue(
                  ModelConstants.FILE_DS_FILE_ID));

          display.getImportForm().saveData();

          display.getUploadForm().submitForm();

        }
      }
    });

Even for me the onSubmitComplete is not trigerred is there a work around, or is 
this functionality part of smartGWT already ?

The onSubmitComplete is not called when using IE.
You have to look back on this page to comment 4 how to enable IE support;
