Add new child to existing column

When adding a child plot to an existing column and then updating the plot appears but then I get the following error:

bokeh.server.protocol.server_handler - ERROR - error handling message Message 'PATCH-DOC' (revision 1): RuntimeError('Cannot apply patch to 8cf5ddd0-9b96-49fc-8099-c792733d0ff5 which is not in the document',)

And my figures come out wonky:

 
    def __init__(...):
        ...
        self.sizing_mode = 'scale_width'
        self.figures = {}
        self.sources = {}
        self.root = column(sizing_mode=self.sizing_mode)

    def add_figure(self, name):
        source = ColumnDataSource({'x': [], 'y': []})
        fig = figure(title=name, tools='', height=150, sizing_mode=self.sizing_mode)
        fig.line(source=source, x='x', y='y')
        self.sources[name] = source
        self.figures[name] = fig
        self.root.children = self.root.children + [fig]

    def update(self):
        for name, counter in self.server.counters.items():
            if name not in self.figures:
                self.add_figure(name)
            else:
                xs = [counter.quantile(i / 100) for i in range(101)]
                ys = [xs[i + 1] - xs[i] for i in range(len(xs) - 1)]
                self.sources[name].data.update({'x': xs, 'y': ys})

Thanks for the test case, just FYI resolving this is one of my top two priorities for 0.12.5

I’m also experiencing this issue.

My version of python and bokeh:

>>> import sys
>>> import bokeh
>>> print(sys.version)
3.6.4 |Anaconda, Inc.| (default, Jan 16 2018, 12:04:33)
[GCC 4.2.1 Compatible Clang 4.0.1 (tags/RELEASE_401/final)]
>>> print(bokeh.__version__)
0.12.13

This is a simplified version of the main.py that creates the error.

# Setup Widgets
window = Slider(title="Change only tab 1", value=0, start=0, end=35, step=7)
prop_txt = TextInput(placeholder='enter prop code', title='PROPERTY CODE:')
run_button = Button(label='Query', button_type='success')

for widget in [window]:
    widget.on_change('value', update)

for widget in [run_button]:
    widget.on_click(query_prop_data)

tab1_plots.children[0] = figure(plot_height=500,
                                plot_width=1000,

tab1 = Panel(child=tab1_plots, title="Tab1")
tab2 = Panel(child=tab2_plots, title="Tab2")

tabs = Tabs(tabs=[tab1, tab2], width=1000)
page_layout = row(children=[inputs, tabs], sizing_mode='fixed')

curdoc().add_root(page_layout)
curdoc().title = "Forecast Analysis"

Only occurs when query_prop_data is called (by clicking the Button)

I start up my server with $bokeh serve --show bokehtest

Each time the query button is clicked I get four lines like this:

2018-01-18 13:48:51,357 Cannot apply patch to aa41f426-0641-4ddf-b418-f0c92bcd3d24 which is not in the document anymore

Not sure if this is a code issue on my part or a bug. Hope that helps!
