Nested pydantic_form not working, just clears page

[jamesbraza]

Describe the bug:

When I try to have nested pydantic_forms, the page just gets cleared out.

Expected behaviour:

I expect the below code snippet to not wipe the screen after the second submit button is pressed.

Steps to reproduce the issue:

import streamlit as st
import streamlit_pydantic as sp
from pydantic import BaseModel, Field

class MinCount(BaseModel):
    min_count: int = Field(default=4, gt=0)

st.title("Test")
input_1 = sp.pydantic_form(key="input-1", model=MinCount)
if input_1:
    input_2 = sp.pydantic_form(key="input-2", model=MinCount)
    if input_2:
        st.write(f"{input_1.min_count=}, {input_2.min_count=}.")

Technical details:

• Host Machine OS (Windows/Linux/Mac): macOS Ventura version 14.5.2, arm64
• Browser (Chrome/Firefox/Safari): Chrome

Here are my requirements with Python 3.11:

pydantic                  2.5.2
pydantic_core             2.14.5
pydantic-settings         2.1.0
streamlit                 1.28.2
streamlit-pydantic        0.7.1

I am installing https://github.com/LukasMasuch/streamlit-pydantic/tree/390a45aba7bf8caccc297c335715cc141db490af directly from GitHub
