Cannot append to tabs anymore

Panel
1

I am using the Tabs layout in panel 0.13.1. As suggested I have created a tuple in tabs like so.

tabs = pn.Tabs(('Tab0', tab0))

However when I try to append to the tab within a callback, the tabs vanish and there is no action to switch to the new tab.

tabs.append(('Tab1',tab1))
tabs.active=1

I have used Tabs in the past in the same way and I could append to tab successfully. Has something changed?

It seems the culprit on my end is a Panel indicator. The Tabs appends and work as intended, but the addition of the indicator makes the Tabs disappear when appending. I am running it on a server. A simplified, example code is below.
I would appreciate any workaround.

from bokeh.plotting import figure
from bokeh.models import Spacer
import panel as pn


def callback(event):
	s2=pn.Column(p2,gauge1)
	tabs.append(('Line',s2))
    tabs.active=1

p1 = figure(width=300, height=300, name='Scatter')
p1.scatter([0, 1, 2, 3, 4, 5, 6], [0, 1, 2, 3, 2, 1, 0])

button1 = pn.widgets.Button(name="Click me", button_type="danger", width=150)
button1.on_click(callback)

gauge1=pn.indicators.Gauge(name='Failure Rate', value=10, bounds=(0, 100))

s1=pn.Column(p1,Spacer(height=20),button1)

p2 = figure(width=300, height=300, name='Line')
p2.line([0, 1, 2, 3, 4, 5, 6], [0, 1, 2, 3, 2, 1, 0])

tabs = pn.Tabs(('Scatter', s1))
tabs.servable()

Hello, I’m pretty much a newbie with Panel and this is my first post here but I hope this can help you.

from bokeh.plotting import figure
from bokeh.models import Spacer
import panel as pn

pn.extension()


def callback(event):
    s2=pn.Column(p2,gauge1)
    tabs.append(('Line',s2))
    tabs.active=1

p1 = figure(width=300, height=300, name='Scatter')
p1.scatter([0, 1, 2, 3, 4, 5, 6], [0, 1, 2, 3, 2, 1, 0])

button1 = pn.widgets.Button(name="Click me", button_type="danger", width=150)
button1.on_click(callback)

gauge1=pn.indicators.Gauge(name='Failure Rate', value=10, bounds=(0, 100))

s1=pn.Column(p1,Spacer(height=20),button1, name = 'Scatter')

p2 = figure(width=300, height=300, name='Line')
p2.line([0, 1, 2, 3, 4, 5, 6], [0, 1, 2, 3, 2, 1, 0])

tabs = pn.Tabs(s1)

By replacing the tuple (‘Scatter’, s1) with just the Column s1 and moving the name to s1, it seems to work for me. I hope this helps you.
