panel/default.xml: /panels should be array and one-indexed

I updated the /panels property to an array here:
https://github.com/Xubuntu/xubuntu-default-settings/commit/d85421cb4139309b0a8168242493c15194d86b33

When I tried making the array one-indexed, the panel constantly reindexed to 0. I'm not sure if this is a bug/feature of the current panel (4.17.3).

Thanks.

Did you use `xfce4-panel-profiles` for that? Looking at its code, it resets the base property "/". Perhaps that's the issue here?

I noticed that when I reset the panel manually, first "/panels" and then "/plugins", the new one is set up properly (one-indexed array). Do you observe the same behavior?

I reset the panel using the Settings Editor. I tried again with just the commandline:

    xfconf-query -r -R -c xfce4-panel -p /panels
    xfconf-query -r -R -c xfce4-panel -p /plugins

Afterwards, the only setting left in xfce4-panel was configver. I added another plugin to the panel, and it was zero-indexed again.

Ah, so you didn't restart the panel? I can observe the same behavior (4.17.4).

My guess is that the old configuration is still in memory, so adding new plug-ins "revives" it. If I monitor the whole channel:

`xfconf-query -c xfce4-panel -mv`

I can see that when I add a new plug-in it appears as:

set: /panels/panel-0/plugin-ids ((null))

and isn't retained after panel restart. What's more interesting is that the default plug-ins are also loaded in the process but the whole panel-0 is inaccessible and unusable: probably because position and size properties weren't set (or wiped during reset).

Resetting both /panels and /plugins, then restarting the panel fixes it. Panel IDs are stored in arrays and start from 1.

To conclude, xfce4-panel (at least the latest version) seems to prefer one-indexing newly added panels but won't refuse older configurations if they're loaded at once.

Thanks for the expanded details. I was finally able to reproduce what you're seeing and applied a patch. Coming in xubuntu-default-settings 23.04.0!

This bug was fixed in the package xubuntu-default-settings - 23.04.0
