Hi,
First of all, congrats for such a great extension!!
I found an issue when I configure the FileSystemDataProvider as non-recursive and with some filters to hide Thumbs.db and .DS_Store files.
FilesystemData root = new FilesystemData(directory, false); //Setting to true, avoids exception
FilesystemDataProvider fileSystem = new FilesystemDataProvider(root);
fileSystem.addFilter(file -> !file.getName().endsWith(".db")); //Remove Thumbs.db
fileSystem.addFilter(file -> !file.getName().equals(".DS_Store")); //Remove DS_Store
Tree<File> tree = new Tree<>();
tree.setDataProvider(fileSystem);
tree.addHierarchyColumn(File::getName, FileTypeResolver::getIcon, this::getFileDescription)
.setAutoWidth(true).setResizable(true).setHeader("File");
tree.expand(directory); //Open root directoryThe exception happens when I expand a directory on the second level order that has something filtered. I'm not really sure if the exception happens because of the deeper implementation of Vaadin TreeDataProvider
// When I expanded the directory, it has 4 items,and one of them is filtered.

Hi, thanks for the nice addon. I have written a TreeData and DataProvider to support the browsing and handling of SMB sources. Lazy loading is supported. My implementation is based on https://github.com/hierynomus/smbj. I would like to know if there is interest to merge it into this project. Some polishment would be needed if it is desired.
The JAR file contains a jrebel.xml in the root which produces warnings when using JRebel:
[2023-01-19 14:15:29] Invalid rebel.xml: Invalid 'dir' defined in class path of rebel.xml (jar:file:/C:/Users/simon/.m2/repository/org/vaadin/filesystemdataprovider/filesystemdataprovider/3.2.0/filesystemdataprovider-3.2.0.jar!/rebel.xml): Directory 'C:/Projects/filesystem-dataprovider-flow/target/classes' does not exist
Please exclude jrebel.xml from the build
Hi,
There is a way to authenticate on remote server with your component?
My vaadin application is running on Ubuntu server, and I needs to browse files on different server (Windows server).
Normally using C# or Python I can impersonate a user and login to the remote server, and browse for files and folders.
Here my code:
Button browse= new Button("browse", ev -> {
if(SessionUtils.getLoggedUser().getTenant().getBasePath() == null || SessionUtils.getLoggedUser().getTenant().getBasePath().length() == 0)
return;
Dialog dialog = new Dialog();
VerticalLayout layout = new VerticalLayout();
//SessionUtils.getLoggedUser().getTenant().getBasePath() = \\ip\folder\
File rootFile3 = new File(SessionUtils.getLoggedUser().getTenant().getBasePath());
FileSelect fileSelect = new FileSelect(rootFile3);
fileSelect.addValueChangeListener(event -> {
File file = fileSelect.getValue();
Date date = new Date(file.lastModified());
if (!file.isDirectory()) {
Notification.show(file.getPath() + ", " + date + ", " + file.length());
} else {
Notification.show(file.getPath() + ", " + date);
}
});
fileSelect.setWidth("500px");
fileSelect.setHeight("500px");
layout.setSizeFull();
layout.setAlignItems(Alignment.CENTER);
layout.setJustifyContentMode(JustifyContentMode.CENTER);
fileSelect.setLabel("Select file");
layout.add(fileSelect);
Button closeBtn = new Button("Chiudi", e -> dialog.close());
layout.add(closeBtn);
dialog.add(layout);
dialog.setCloseOnEsc(true);
dialog.open();
});With this code, and a local path on the ubuntu server I can browse files, but not on the remote server that requires login.
I needs to impersonate the user to respect the permissions assigned.
