Configuration of "Tab Panel" is lost when 1st tab has no panel assigned
Open, Needs TriagePublic


When creating a "Tab Panel" and leaving the 1st tab blank (or even any number of tabs (e.g. 1/2 blank, 3 assigned), the whole "Tab Panel" configuration will be lost when saving.

How to Reproduce?

  • Create a new "Tab Panel" on a Dashboards or create a new one
  • Configure it as shown in the screenshot below (1/2 blank, 3: "Name: Tasks", "Panel: W4 Assigned Tasks")
  • Click on Save Panel

What happens

  • The resulting "Tab Panel" will be completely empty
  • Opening the configuration dialog again shows a completely emptied configuration

What should happen

One of the following options:

  • A warning dialog tells the user to fill up the tabs starting from 1… (bad UX, but still OK)
  • The configuration is processed automatically to remove empty items and move later ones to the 1st places
  • The configuration accepts empty items, but the resulting "Tab Panel" just ignores them

What are you attempting to do here or was this accidental?

This was accidental and I just feel like this is bad UX (losing existing configuration on submit).

@epriestley as far as I can tell, empty tokenizers do not POST an input to evaluate.

We should still be able to handle this case, but I can take a look at what's happening since this is a nonstandard element and the fix is probably easy once I understand what's going on with the logic.

I think i need to set the inputs with an actual key, not just [], so [$ii]

amazing what sleep will accomplish

Based on like 10 seconds of looking at the code that's where I'd start. 💯

Thinking about this again, what about making this hard-coded numbered list instead a list of draggable items like it's used in Menu Configuration?

I just plan to fix the bug. That's the hard part of a 2-person team with thousands of open issues. Pick and choose the battles.

Yeah I can't seem to fix this ad hoc. My guess is it's never worked to allow you to skip the first tab. If I fix the error states, it then breaks existing tab panels. So we'd need to build a migration.

T12708 is the same root bug. This was more engineering than I could handle.
