I'm trying to implement a full file manager using the Upload component to a

Directory Filesystem DataProvider Add-on

I’m trying to implement a full file manager using the Upload component to allow users to upload files to the server.

I have the FilesystemDataProvider working except for one issue.

When I upload a new file, I call FilesystemDataProvider.refreshAll().
The treegrid redraws all of the items but it doesn’t show the newly uploaded file.
I’ve check and the file exists before the I call refreshAll().
If I hit F5 to refresh the browser page the file then appears.

upload.addSucceededListener(event ->
			{
				fileSystem.refreshAll();
			});

File rootFile = new File(FileStore.instance().managedStorePath);
		FilesystemData root = new FilesystemData(rootFile, false);
		fileSystem = new FilesystemDataProvider(root);
		tree = new TreeGrid<>();
		tree.setDataProvider(fileSystem);
		tree.addHierarchyColumn(file -> file.getName()).setHeader("Name").setAutoWidth(true).setResizable(true);
		tree.addColumn(file -> file.length()).setHeader("Size");
		tree.addColumn(file -> file.isDirectory() ? "Directory" : "File").setHeader("Type");
		tree.addComponentColumn(file -> buildDelete(file)).setHeader("Size");
