Anyone been able to get the sap.ca.ui.FileUpload control working with a Gateway OData service?

Question

Hi,
I have been trying to get the sap.ca.ui.FileUpload control working with an OData Gateway service, specifically /IWPGW/TASKPROCESSING which is the service used by both Fiori Approve Requests and the Unified Inbox.
I have looked at the sample application in the Explored at SAPUI5 Explored
I have managed to replicate that and get it to work, but as soon as I switch it from a JSONModel to an ODataModel I get javascript errors from within the setModel method of the control. I have redefined that method and corrected the errors, which enables me to get a bit further, but then I hit more errors, and other strange behaviour.
Either I am doing something completely wrong, or to me it appears as if this control is still extremely buggy and maybe either not designed to work with an ODataModel, or just hasn't been tested using an ODataModel. I'm hoping it is my mistake.
So has anybody out there successfully managed to use this control connecting it to a Gateway OData service? If so please share your experience.
Thanks,
Brad

Hi Pauline,
Same issue I had, I switched to using a sap.m.list and handling the press as follows:
attachmentsList.bindItems(workItemPath + "/Attachments", new sap.m.StandardListItem({
                           type: sap.m.ListType.Active,
                           title: "{FileName}",
                           description: "{CreatedByName}",
                           icon: "sap-icon://doc-attachment",
//                         counter: "{FileSize}",
                      info: {path : "CreatedAt", formatter: dateTimeFormatter},
                      tap: function(oEvent){
                            var oContext = oEvent.getSource().getBindingContext();
                            var media_src = oContext.getProperty().__metadata.media_src;
                            sap.m.URLHelper.redirect(media_src, true);
                    }), new sap.ui.model.Sorter("CreatedAt", true));
So sap.m.URLHelper.redirect(media_src, true); is what loads the attachment.
See the full function handler:
function(oEvent){
function(oEvent){
              var oContext = oEvent.getSource().getBindingContext();
              var media_src = oContext.getProperty().__metadata.media_src;
        sap.m.URLHelper.redirect(media_src, true);
This should be enough if you only want to list and display the attachments, then you don't really need the FileUploader control as that is more advanced and handles upload, display, change and deletion of files.
I only needed to upload and display files, so I used a list to display it and created a separate upload button using the sap.ui.unified.FileUploader control.
Hope that helps.
Cheers,
Brad
