HabPanel not switching back to first dashboard

[chevdor]

Background

HabPanel allows OH to control the currently displayed Dashboard using one of the panel settings:

It is usually defined as an item such as:

String    HabPanel_Screen          "HabPanel Screen"         <screen>         (VirtualSwitch)

The idea is that changing the content of the string, HabPanel will switch to that Dashboard, should the string match an existing Dashboard. Simple, yet very powerful.

Sample use case

I was experimenting with a simple use case that I provide here only to illustrate how I got there.

Let's consider I have 3 dashboards:

• A: Main
• B: Doors & Windows
• C: Foobar

Below I will refer to Dasboards A, B and C since what they are does not matter much.

In my case, usually, HabPanel shows Main (A). When a door or window is opened, it will switch to Doors & Windows (B). After N seconds, it will come back to Main (A).

Nice story but that does not work.

The problem

The rule switching A -> B works fine. A window is opened (for instance), OH will update the HabPanel_Screen content and the B Dashboard will be shown.

So far, everthing works as expected.

The issue is related to coming back to Dashboard A. I am using a timer (but that part does not matter) and switching back to A is simply ignored.

Expected behavior

Considering 2 Dashboards both of the following work:

• ✅ switch from A to B
• ❌ switch from B back to A

A being the main "default" dashboard.

Steps to reproduce

• from a standard install with one dashboard (A), create a second dashboard
• create a switch to test
• create an Item String HabPanel_Screen "HabPanel Screen" <screen>
• Configure HabPanel to use HabPanel_Screen to switch dashboard
• implement a rule that switch from A to B and from B to A

Additional information

It is important to notice that I run into this issue ONLY if A is the first/default dashboard.
It you already have a dashboard and create 2 new dashboards for the test, it will be working all fine as it does for me.

I see the issue directly in the browser:

• ✅ http://domopi2:8080/habpanel/#/view/B
• ❌ http://domopi2:8080/habpanel/#/view/A

I see the URL changing but the page does not reload with A.

I could fetch the following error in the console:

I ended up deleting my "first" dashboard as I think it was "corrupted".
Surprising though since I built the second dashboard by simply copying all the widgets from A to B and B works just fine.
So when I mentioned "First/Default" Dashboard above is NOT relevant. The issue is that somehow, my A Dashboard got corrupted, still loads as default dashboard but does not when switched to.
