Page Reload on Cache Miss #10199
Description
Checklist
- I have searched the existing issues for similar issues.
- I added a very descriptive title to this issue.
- I have provided sufficient information below to help reproduce this issue.
Summary
I am noticing behaviour very similar to the behaviour described in this issue when using v1.41.1. In particular, I'm noticing that if I cause a rerun by pressing "R" and there is a cache miss, then sometimes the page reloads, element status is lost (e.g. active element, but not state like selected items) and scroll position is lost (the page is scrolled to the very top).
I first noticed this on a large page with many elements and several cached_data references. I was able to narrow it down to a single simple page show in the reproducible code.
The problem seems to come up when there are multiple cached_data functions that all expire together and all need to be run again as part of the same app rerun.
The attached video shows the reload happening consistently on the cache miss, i.e. every 3 seconds. I've found that if I reduce the number of cached_data functions, then this is less likely to happen.
Reproducible Code Example
import streamlit as st
import pandas as pd
@st.cache_data(ttl=3, show_spinner=True)
def get_table(table_name: str) -> list:
return [{"name": "AUD"}, {"name": "USD"}, {"name": "EUR"}, {"name": "GBP"}]
def get_table_as_dataframe(table_name: str) -> pd.DataFrame:
return pd.DataFrame(get_table(table_name=table_name))
currencies1 = get_table_as_dataframe("1")
currencies2 = get_table_as_dataframe("2")
currencies3 = get_table_as_dataframe("3")
currencies4 = get_table_as_dataframe("4")
currencies5 = get_table_as_dataframe("5")
currencies6 = get_table_as_dataframe("6")
currencies7 = get_table_as_dataframe("7")
currencies8 = get_table_as_dataframe("8")
currencies9 = get_table_as_dataframe("9")
currencies10 = get_table_as_dataframe("10")
currencies11 = get_table_as_dataframe("11")
currencies12 = get_table_as_dataframe("12")
currencies13 = get_table_as_dataframe("13")
currencies14 = get_table_as_dataframe("14")
currencies15 = get_table_as_dataframe("15")
st.markdown("### Top of the page")
st.table(currencies1)
st.table(currencies1)
st.table(currencies1)
st.table(currencies1)
st.table(currencies1)
st.multiselect(
"What are your favorite currencies?",
currencies1["name"],
)
st.text_input("Text")Steps To Reproduce
- Scroll to the bottom of the page
- Make a currency selection
- Hit "R" until the cache expires
- the page should reload and be scrolled to the top
- the previous selection is STILL in place, i.e. not all element state is lost
- Scroll to the bottom again
- Enter text into the text box and press "enter" until the cache expires
- the page should reload and be scrolled to the top
- the active selection of the text input IS LOST
Expected Behavior
The page should not be scrolled to the top and the active element should remain active.
Current Behavior
There is nothing in the browser console.
