Question

I opened as many as 2 dialogs. simultaneously. and of course in the first dialog there is a button to open the second dialog. and when the two dialogs are closed . you can see an empty white container. and must be reloaded

Code sample

self.dialogForgotPassword = AlertDialog(
			title=Container(
				bgcolor="red",
				padding=10,
				width=400,
				content=Text("Forgot Password ",weight="bold",
					color="white"
					)
				),
			content=Column([
				Text("Insert Username If You Have",weight="bold"),
				self.username,
				]),
			actions=[
			ElevatedButton("Find User ",
				bgcolor="red",color="white",
				on_click=self.finduser
				)
			],
			actions_alignment="end"
			)
		self.dialogResetPassword = AlertDialog(
			title=Container(
				bgcolor="red",
				padding=10,
				width=400,
				content=Text("Reset Password ",weight="bold",
					color="white"
					)
				),
			content=Column([
				Text("username Found",size=25,weight="bold"),
				self.password,
				ElevatedButton("Reset Now",
					bgcolor="red",color="white",
					on_click=self.resetpassword
					)
				])
			)

def resetpassword(self,e):
		try:
			new_password = self.password.value
			user_id = self.resetid.value
			query = f"UPDATE users SET password='{new_password}' WHERE user_id={user_id}"
			cursor.execute(query)
			conn.commit()
			print("Success Change password")
			self.dialogResetPassword.open = False
			self.page.snack_bar = SnackBar(
            Text("Password Success Change",size=30),
            bgcolor="green"
            )
			self.page.snack_bar.open = True
			self.page.update()
		except Exception as e:
			print(e)
			print("Error CHECK !!!")

	def finduser(self,e):
		print("find user")
		username = self.username.value
		cursor.execute("SELECT username,user_id FROM users WHERE username=?", (username,))
		result = cursor.fetchone()
		if result is None:
			self.dialogForgotPassword.open = False
			self.username.value = ""
			self.page.snack_bar = SnackBar(
            Text("Username Not Found",size=30),
            bgcolor="red"
            )
			self.page.snack_bar.open = True
			self.page.update()
		else:
			print(result[1])
			self.resetid.value = result[1]
			self.dialogForgotPassword.open = False
			self.page.update()
			self.page.dialog = self.dialogResetPassword
			self.dialogResetPassword.open = True
			self.page.update()

	def forgotpassword(self,e):
		self.page.dialog = self.dialogForgotPassword
		self.dialogForgotPassword.open = True
		self.page.update()

• I have searched for answers to my question both in the issues and in previous discussions.

@bobwatcherx , see if this helps:

• Not really sure why, but if you wait for like a second or sub-second after you reassign the page.dialog to a different dialog and before you call the page.update(), the blank page would not happen. Maybe it needs a little bit of time to update or something, I don't know.

• In the else block of findUser(), insert a time.sleep(1) between the following 2 lines:

self.dialogResetPassword.open = True
time.sleep(1) # you can do a sleep for sub-second timings too
self.page.update()
