Cells only display values if scrolled out of view once about jupyterlab-hdf5

@telamonian Thanks for the new release.

Indeed, I also encountered this issue, and I was able to view the data by minimizing and maximizing the view by dragging the filebrowser back and forth.

I've definitely seen similar issues before during development. However, I can't reproduce the issue locally.

@loichuder @cnydw What version of Jupyterlab are each of you running? Can you please run the following in a terminal:

jupyter labextension list
jupyter serverextension list

and post the output here in this thread?

I found a bug where small datasets were rendering blank when initially shown. I fixed it and did a v0.4.1 bugfix release. @cnydw Can you please try out v0.4.1 and see if it fixes your issue?

Unfortunately, @loichuder I don't think the bug that I found is directly related to your problem, since I wasn't seeing any errors on the console. I suspect you might have a version mismatch between your jupyterlab-hdf5 labextension and serverextension, so please run those commands I posted above and post the output

@telamonian v0.4.1 indeed fixes the blank datasets issue, thanks for the quick fix 👏 ! You are right, it was only for small datasets as the examples of the repo were working fine.

For the other error, I reproduced it on another computer with the following steps:

• Launch jupyter lab from a CLI in a given folder and open a HDF5 file with it.
• Quit JupyterLab and change folder
• Run jupyter lab once again in the new folder and you should see 403 in the console as it cannot resolve the relative paths anymore.

Here are the outputs of jupyter labextension list:
@jupyterlab/hdf5 v0.4.1 enabled OK

and jupyter serverextension list:

    jupyterlab  enabled 
    - Validating...
      jupyterlab 2.2.8 OK
    jupyterlab_hdf  enabled 
    - Validating...
      jupyterlab_hdf 0.4.1 OK

Note that I installed jupyterlab (and the extensions) in a venv created by pew. Not sure if that's relevant.

I will close this since 0.4.1 fixed the issue.
