issue with state

[george-codes]

I had an existing app with a callback include State, but now seems to throw an error regarding "not defined". Here is a simple example that demonstrates the error:

import dash
import dash_core_components as dcc
import dash_html_components as html
from dash.dependencies import Input, Output, State
from jupyter_plotly_dash import JupyterDash

app = JupyterDash('InteractivePyDEFDemotest')

app.layout = html.Div([
    dcc.Input(id='input-1-state', type='text', value='Montréal'),
    dcc.Input(id='input-2-state', type='text', value='Canada'),
    html.Button(id='submit-button-state', n_clicks=0, children='Submit'),
    html.Div(id='output-state')
])
@app.callback(Output('output-state', 'children'),
              [Input('submit-button-state', 'n_clicks')],
              [State('input-1-state', 'value'),
               State('input-2-state', 'value')])
def update_output(n_clicks, input1, input2):
    return u'''
        The Button has been pressed {} times,
        Input 1 is "{}",
        and Input 2 is "{}"
    '''.format(n_clicks, input1, input2)

My dash version is 1.11 My jpyter-plotly-dash version is 0.4.0

If I can narrow down the issue even more, I will post back. thanks!

Can you try upgrading to the most recent version of django-plotly-dash? That should address this issue

Thanks, that did the trick! All set and back to normal :)
