UploadItem.setDefaultProperties() problem when changing the title?

[Blama]

Hi Isomorphic,

I wanted to change the FormItem title for BatchUploader UploadItem in this sample. I got it working but wondered why my 1st approach did not work:

I'm pretty sure that the generated item is an UploadItem after using the Developer Console's watch tab.
I tried this at application startup at the very top of my onModuleLoad before any draw().

        UploadItem ui = new UploadItem() {
            {
                setTitle(i18n.fileToUpload());
            }
        };
        UploadItem.setDefaultProperties(ui);

But the title is still "Upload file" and not my string "File to upload".

Using this code it is working, but shouldn't the 1st method work as well?

        UploadItem ui = new UploadItem();
        ui.setTitle(i18n.fileToUpload());
        BatchUploader.changeAutoChildDefaults("uploadFileItem", ui);

I tired this using latest v10.1p_2017-01-03.

Thank you & Best regards

Hi Isomorphic,

I spoke to early:
The changeAutoChildDefaults() does break the main BatchUploader functionality. After hitting upload there is no data in the grid.
If I remove the three lines it is working again.

The first approach would be expected to set a system-wide default title for all UploadItems anywhere. So it would not be expected to work in this case, since the BatchUploader sets a more specific title.

The second approach is also wrong. The item in question is actually a FileItem, not an UploadItem. Since you just want to set title, there is no reason for you to reiterate the specific class of the item - just use a FormItem. This will then avoid broken functionality, which comes from your attempt to override what class is being used.
