MultiFileUploader Plugin

That's crazy! So you're basically saying that this is no longer working in any of these browsers?
So basically not working at all?

As to Opera, It's never been tested on my end, but IE/Firefox/Chrome/Safari was working in all the tests I've done...
So what's special on your server that make all fail?

(Note also that IE9 drop can only be used in conjunction with Chrome Frame, if Chrome Frame is not present, you cannot drag and drop (but you should still be able to upload files))

Is there any firewall? Do you have a proxy (Apache/NGinx)? How do you deal with the files? What can possibly be happening that could be that different from the tests I've done (on real server as well)?

I'm puzzled.

What is the actual external URL of your server???

Because I see that your blank window is showing 'localhost:8080' which is clearly wrong for a client...
What is the URL that you see in the browser in the main frame when you call multiFile_btn(event)?

Actually, since you are behing a Apache Httpd server, Servoy doesn't see the same address that your client sees, so this could be a problem (depending on the kind of external URL your main page has).
Maybe I could add a parameter in the server admin to allow you to declare the external address of the server (when different from localhost:8080).

The calls to blueimp.github.com is for the css and bootstrap js.
I will embed them all in the /jfqu/ folder in a next version, but I doubt this is causing the issue here.

Thanks for the infos! My SMPT is down so I couldn't answer by email, will give it a try.

What's for sure looking at your code is that the fact that the files are not displayed has nothing to do with the plugin but rather with the way you are adding your records.

Instead of adding via the form and then try to sort the relationship to refresh, you should create the record through the relationship like this (and no need to convertToJSFile, files is already a JSFile[]):

for (var i = 0; i < files.length; i++) {
    var obj_file = files[i];
    var rec = contacts_to_media_ct.getRecord(contacts_to_media_ct.newRecord());
    rec.file_size        = obj_file.size();
    rec.file_blob         = obj_file.getBytes();
    rec.filename         = obj_file.getName();
    rec.file_type        = obj_file.getContentType();
    rec.zrid_contact     = vContID;
    rec.created_date    = new Date();
    rec.created_by    = vUser;
}    
databaseManager.saveData(contacts_to_media_ct);

Have changed code but still have same issue. Tried Firefox on OSX plus a Win7 laptop - files are being uploaded and can be seen almost immediately in a 2nd client's browser but the Client used to upload is locked until manual 'Refresh'.

Revised code as suggested:

/**
 * @param {JSEvent}    event
 * @properties={typeid:24,uuid:"6494DD5E-719B-4708-B85F-0A2F7F06F19B"}
 */
function multiFile_btn(event) {
    //    121208
    //    plugins.MultiFileUploader.callMultiUpload(uploadCallBack, 'in/a/sub/', {height:600,width:700,location:0,menubar:0,toolbar:0,resizable:1,status:0,scrollbars:0})
    plugins.MultiFileUploader.callMultiUpload(uploadCallBack2);
}

/**
 * @param {Array<plugins.file.JSFile>}    files
 * @properties={typeid:24,uuid:"D6A364AD-895A-4B0F-AF17-3D4D39AC9E22"}
 */
function uploadCallBack2(files) {
    //    130117                                    //     * @param {Array<JSFile>} files
    var vContID    = forms._2__Contacts.idct;
    var vUser    = globals.curr_User_Name;

    for (var i = 0; i < files.length; i++) {
        var obj_file = files[i];
        var rec = contacts_to_media_ct.getRecord(contacts_to_media_ct.newRecord());
        rec.file_size          = obj_file.size();
        rec.file_blob          = obj_file.getBytes();
        rec.filename           = obj_file.getName();
        rec.file_type          = obj_file.getContentType();
        rec.zrid_contact       = vContID;
        rec.created_date       = new Date();
        rec.created_by        = vUser;
    }    
    databaseManager.saveData(contacts_to_media_ct);
}

Check v1.0.5

I did a few changes:
1/ no external calls to blueimp.github.com for external css/js files anymore, all files are now embedded in the jqfu sub-folder
2/ call to window.opener.location.reload() upon successful upload
3/ getting rid of chrome frame in IE as this prevents the reload

I've tried on Win IE/Firefox/Chrome and Mac OS X Safari and it worked fine from a server.

Only thing is that you cannot drag and drop to IE anymore, because it's not using Chrome Frame (if you have it), so it reverts to IE default behavior which is: force usage of "Add files..." and can only select one file at the time. This is a limitation of IE, and I cannot do much against that.

Make sure you overwrite the plugin in /application_server/plugins/, but also the /jqfu folder in /application_server/server/webapps/ROOT/
Let me know if this works for you too and I'll close the issue.

Bingo! Yes that's done the trick very nicely.

Tested on clients live system with Mac/Firefox and Win/Firefox and both worked fine. Many thanks for your great support!
