import os
import discord

class CustomView(discord.ui.View):
    def __init__(self):
        super().__init__(timeout=None)

        self.button = discord.ui.Button(label="Example") 
        self.button.custom_id = "custom_id"
        self.button.callback = self.callback

        self.add_item(self.button)

    async def callback(self, interaction: discord.Interaction):
        await interaction.respond("Button clicked!")

bot = discord.Bot(intents=discord.Intents.all())

@bot.slash_command(name="test")
async def test_modal(ctx: discord.ApplicationContext):
    view = CustomView()
    await ctx.respond(content=f"{view.is_persistent()=}\n{view.button.is_persistent()=}", view=view)

bot.run(os.getenv("TOKEN"))

Expected Results

The setter for Button.custom_id does set the attribute on the latest commit: https://github.com/Pycord-Development/pycord/blob/ca91b3e22d9f521dbb6f1da4595efea7093fc276/discord/ui/button.py#L187

I cannot repro this.

import discord

button = discord.ui.Button(label="hello")
button.custom_id = "my_custom_id"
print(
    button.custom_id,  # my_custom_id 
    type(button.custom_id),  # <class 'str'>
    button.is_persistent(),  # True
    button._provided_custom_id,  # True
) #  True True


button2 = discord.ui.Button(label="hello", custom_id="another_custom_id")
print(
    button2.custom_id,  # another_custom_id 
    type(button2.custom_id),  # <class 'str'>
    button2.is_persistent(),  # True
    button2._provided_custom_id,  # True
) # <class 'str'> True True


button3 = discord.ui.Button(label="hello")
print(
    button3.custom_id,  # a0070e0ae1a349e5445045c674c15e33 
    type(button3.custom_id),  # <class 'str'>
    button3.is_persistent(),  # False
    button3._provided_custom_id,  # False
)

I think you forgot to call Bot.add_view, this makes it actually persistent.
