vaadin 8 FilesystemContainer alternative

Question

I used FilesystemContainer in a Vaadin 7 application to populate the contents of a com.vaadin.ui.Tree for viewing and selecting files on the server.

tree.setContainerDataSource (new FilesystemContainer (new File ("o: \\")));

However, when migrating this application to Vaadin 8 I did not find an alternative to the FilesystemContainer. Could anyone tell me which way would be the best?

Answer 1

This is missing feature in Vaadin 8 and subsequent versions, but thanks for the idea. It is not very complex task to implement FilesystemDataProvider in Vaadin 8, thus I made one:

https://vaadin.com/directory/component/filesystem-dataprovider-add-on

The source code and demo application are in GitHub, see demo application how to use:

https://github.com/TatuLund/FilesystemDataProvider/blob/master/filesystemdataprovider-demo/src/main/java/org/vaadin/filesystemdataprovider/demo/DemoUI.java

There is version also for the new Vaadin versions like Vaadin 14 as well. In Vaadin 14 version there is FTP variant too.
