Streamlit: Streamlit number_input reverting to default in column layout

[kurt-rhee]

Summary

Streamlit number_input reverts back to default value if clicking + or - buttons or if entering a new value in column layout. I believe that number_input with float does not work in column layout, while integer number_inputs work okay.

https://discuss.streamlit.io/t/problem-with-number-input/3539

Steps to reproduce

What are the steps we should take to reproduce the bug:

    # --- Latitude, Longitude ---  not workign in column layout, working fine in st.number_input
    latitude = c1.number_input('latitude', value=latitude)
    longitude = c1.number_input('longitude', value=longitude)

Expected behavior:

I would expect changes to the number input to not revert to default

Actual behavior:

reversion to default on any change

Is this a regression?

yes, this used to work okay, but I was not using column layouts before.

Debug info

• Streamlit version: 0.68
• Python version: 3.7
• Using Conda
• OS version: Windows 10

Thanks for the report @kurt-rhee, this looks awfully similar to https://github.com/streamlit/streamlit/issues/2145#issuecomment-707377155 hopefully they will be solved together!

@kurt-rhee I believe #2173 should address this problem and it will be in the next release soon. If nightly succeeds tonight, you can also try it out.

Fingers crossed!
