Error In Devtools While Updating Open In Setting
Introduction
In this article, we will explore an issue that occurs when updating the "Open in" setting in the options menu of a web application. The error is visible in the DevTools console and is related to a warning about updating a component while rendering a different component. We will analyze the error message, identify the root cause, and provide a solution to fix the issue.
Scenario
To reproduce the issue, follow these steps:
- Log in to the web application.
- Go to any tab, for example, the "People" tab.
- Click on the options menu and select "Layout" > "Open in".
- Change the option to a different value.
Actual Behavior
When you follow the above steps, you will see an error in the DevTools console. The error message is:
ObjectOptionsDropdownMenuViewName.tsx:65 Warning: Cannot update a component (`DropdownOnToggleEffect`) while rendering a different component (`ObjectOptionsDropdownMenuViewName`). To locate the bad setState() call inside `ObjectOptionsDropdownMenuViewName`, follow the stack trace as described in https://reactjs.org/link/setstate-in-render
Expected Behavior
The expected behavior is that there should be no error in the DevTools console when updating the "Open in" setting.
Error Analysis
The error message indicates that there is a warning about updating a component while rendering a different component. This is a common issue in React applications, especially when using stateful components.
To analyze the error further, we need to look at the stack trace provided in the error message. The stack trace shows the call chain of the components that led to the error.

The stack trace shows the following components:
ObjectOptionsDropdownMenuViewName
ObjectOptionsDropdownMenuContent

Root Cause
The root cause of the error is that the ObjectOptionsDropdownMenuViewName
component is updating its state while rendering a different component. This is causing the warning about updating a component while rendering a different component.
Solution
To fix the issue, we need to ensure that the ObjectOptionsDropdownMenuViewName
component is not updating its state while rendering a different component. We can achieve this by using the useState
hook to update the state only when the component is not rendering.
Here is an example of how we can fix the issue:
import { useState, useEffect } from 'react';
const ObjectOptionsDropdownMenuViewName = () => {
const [isOpen, setIsOpen] = useState(false);
useEffect(() => {
if (isOpen) {
// Update the state here
setIsOpen(false);
}
}, [isOpen]);
return (
// Render the component here
);
};
In this example, we are using the useState
hook to update the isOpen
state only when the component is not rendering. We are also using the useEffect
hook to update the state only when the isOpen
state changes.
Conclusion
In this article, we analyzed an issue that occurs when updating the "Open in" setting in the options menu of a web application. We identified the root cause of the error, which was that the ObjectOptionsDropdownMenuViewName
component was updating its state while rendering a different component. We provided a solution to fix the issue by using the useState
hook to update the state only when the component is not rendering.
Best Practices
To avoid this issue in the future, follow these best practices:
- Use the
useState
hook to update the state only when the component is not rendering. - Use the
useEffect
hook to update the state only when the state changes. - Avoid updating the state while rendering a different component.
- Use the
React.memo
function to memoize the component and prevent it from re-rendering unnecessarily.
Introduction
In our previous article, we analyzed an issue that occurs when updating the "Open in" setting in the options menu of a web application. We identified the root cause of the error and provided a solution to fix the issue. In this article, we will answer some frequently asked questions related to this issue.
Q: What is the root cause of the error?
A: The root cause of the error is that the ObjectOptionsDropdownMenuViewName
component is updating its state while rendering a different component. This is causing the warning about updating a component while rendering a different component.
Q: How can I fix the issue?
A: To fix the issue, you can use the useState
hook to update the state only when the component is not rendering. You can also use the useEffect
hook to update the state only when the state changes.
Q: What is the difference between useState
and useEffect
?
A: useState
is a hook that allows you to add state to a functional component. It returns an array with two values: the current state value and a function to update the state. useEffect
is a hook that allows you to run a function after rendering a component. It takes a function as an argument and runs it after the component has been rendered.
Q: Why is it important to avoid updating the state while rendering a different component?
A: Updating the state while rendering a different component can cause unexpected behavior and errors in your application. It can also cause the component to re-render unnecessarily, which can lead to performance issues.
Q: How can I prevent the component from re-rendering unnecessarily?
A: You can use the React.memo
function to memoize the component and prevent it from re-rendering unnecessarily. This function takes a function as an argument and returns a memoized version of the component.
Q: What is memoization?
A: Memoization is a technique used to cache the results of expensive function calls so that they can be reused instead of recalculated. In the context of React, memoization is used to cache the results of component rendering so that they can be reused instead of recalculated.
Q: How can I use React.memo
to memoize a component?
A: You can use React.memo
to memoize a component by wrapping the component with the React.memo
function. For example:
import React from 'react';
const MyComponent = () => {
// Render the component here
};
const MemoizedComponent = React.memo(MyComponent);
Q: What are some best practices for avoiding this issue?
A: Some best practices for avoiding this issue include:
- Use the
useState
hook to update the state only when the component is not rendering. - Use the
useEffect
hook to update the state only when the state changes. - Avoid updating the state while rendering a different component.
- Use the
React.memo
function to memoize the component and prevent it from re-rendering unnecessarily.
By following these best practices, you can avoid this issue and ensure that your React application is stable and efficient.
