Directory Explorer Tree Grid

Hi, I’ll be honest and say that I have not been involved in any Vaadin based projects for a number of years, but I do check back one in a while to see how the environment has progressed. So it was nice to see that this Vaadin sponsored addition is now a work in progress as an ‘Explorer Tree’ component was something that was always something that would have improved the admin GUI of the past projects.

I hope you are looking for feedback as here is some

  • Currently the demo is not working, instead it returns “There was an exception while trying to navigate to ‘’ with the exception message ‘Unable to create an instance of ‘com.vaadin.componentfactory.explorer.SimpleView’. The constructor threw an exception.’ “

  • One addition to improve its role within many admin GUIs would be to allow easy support for hierarchical checkbox selection, so that a checkbox can be displayed next to each parent and/or child and when ticked/unticked the selection is recursively placed on all sub parents/childen.

Hi,

Thank you for your feedback.
Sorry for the problem with the demo. It has been fixed and you should be able to use without any errors.

For the second part, I’ve opened a github ticket, so it’s easier to track: https://github.com/vaadin-component-factory/explorer-tree-grid-flow/issues/1

I will check the add-on can help you in this case or if it doesn’t help at all then I will create a ticket in the vaadin-grid repository.
