Pipeline node properties not opening and blank screen is shown, Also in inputs -> Filename -> Browse is not showing files and folder.

[r5shivam]

Describe the issue

1. In Kubeflow pipeline with elyra when I try to open node proerties it shows blank screen first time, then if I close and reopen the pipeline file node properties opens successfully.
2. In node properties if I try to Browse and select the component file it just shows empty panel with nothing to select.

To Reproduce
Steps to reproduce the 1st behavior:

1. Go to 'Node Component'
2. Click on 'Open properties'
3. Close the 'Pipeline File'
4. Open the 'Pipeline File'
5. Now try to open node properties it will work.

Steps to reproduce the 2st behavior:

1. Go to 'Node Properties'
2. Click on 'Browse in Filename'
3. Try to change the directory in the panel shown after 2nd step.
4. You'll get empty panel with nothing to select.

Screenshots or log output
If applicable, add screenshots or log output to help explain your problem.

Expected behavior

1. Node properties should open the first time.
2. Browse for Filename should show all the files/directories.

Deployment information
Describe what you've deployed and how:

• Elyra version: =~ 3.13.0, 3.14.2, 3.14.0, 3.14.1

A quick comment about the last screen capture. In general the file picker will only display files of the pre-selected type. For example, the file picker for a Python component will only display files with the .py extension. The file picker should also display subdirectories, irrespective of whether they contain files of the selected type or not.

It appears that this might be a regression issue with how the the file picker handles subdirectories. I've confirmed the problem using the following directory layout in the Jupyterlab work directory:

afile.py
adir/anotherfile.py
adir/thirdfile.py

Note that this behavior is not file type specific (e.g. Python vs Jupyter notebook)

• [Works as expected]
  • Create a new pipeline
  • In the file browser navigate to the adir subdirectory and drag a file onto the canvas to create a generic node
  • Open the node's properties: the file selection is properly reflected in the UI
  • Choose another file from the same subdirectory
• [Does not work]
  • Create a new pipeline
  • In the file browser navigate to the Jupyterlab work directory and drag a file onto the canvas to create a generic node
  • Open the node's properties: the file selection is properly reflected in the UI
  • Open the file picker
  • [Issue] The subdirectory adir is not listed and no files can be selected from this directory location
• [Does not work]
  • Create a new pipeline
  • Create a generic node using the Python file component
  • Open the node's properties
  • Open the file picker
  • [Issue] The subdirectory adir is not listed and no files can be selected from this directory location

Hey guys, any updates on this? I was trying Elyra out for an MVP proposal, and this came up, and seems quite basic not to be working 😢

@AlirezaSadeghi While I see the issues reported by @ptitzler overall I was able to get all other stuff working by using drag and drop or selecting files from the Jupyter Browser. Is this actually blocking you? Would you be willing to help with the fix?

Any updates on this? I'm facing the same issue. I know jupyterlab > 4 is not supported but are there any plans to start supporting it?

elyra==3.15.0
jupyterlab==4.0.9
notebook==7.0.6
