Hi all,
I am trying to create a bokeh (3.7.0) data analysis application. With different tabs for different analysis types, e.g. lineplots, histogram etc.
In this little example i am trying to dynamically add tabs with figures in them. It works as long as the second tab does not include a figure. Anyone knows how to solve it?

def tab1():
w_1 = Div(text="<b>T1</b>", styles={'font_family': 'arial', 'text_align': 'center', 'font-size': '20px', 'color': 'blue'}, width=200, height=100)
p1 = figure(width=300, height=300)
p1.scatter([1, 2, 3, 4, 5], [6, 7, 2, 4, 5], size=20, color="navy", alpha=0.5)
w_execute = Button(label='Execute', name='Execute')
l1 = layout([[w_1],
[p1],
[w_execute]])
t1 = TabPanel(child=l1,title="T1")
tabs = Tabs(tabs=[t1])
def func_run(new):
add_t2(t1)
w_execute.on_click(func_run)
curdoc().add_root(tabs)
def add_t2(t1):
curdoc().clear()
t2 = tab2()
tabs = Tabs(tabs = [t1, t2])
curdoc().add_root(tabs)
def tab2():
w_2 = Div(text="<b>T2</b>", styles={'font_family': 'arial', 'text_align': 'center', 'font-size': '20px', 'color': 'blue'}, width=200, height=100)
p2 = figure(width=300, height=300)
p2.scatter([1, 2, 3, 4, 5], [6, 7, 2, 4, 5], size=20, color="navy", alpha=0.5)
# l2 = layout([[w_2],
# [p2]]) # Does not work
l2 = layout([[w_2]]) # Works
t2 = TabPanel(child=l2,title="T2")
return t2
tab1()
