Warning: React does not recognize the `iconPosition` prop on a DOM element. (v10.8.3)

[lekhnath]

Describe the bug

React does not recognize the iconPosition prop on a DOM element when iconPosition prop in IconField is used with AutoComplete component.

Reproducer

https://stackblitz.com/edit/vitejs-vite-o12afk

System Information

react: 18.3.1
primereact: 10.8.3
typescript: 5.6.2

Steps to reproduce the behavior

1. Go to issue reproducer link
2. Inspect the console.

Expected behavior

AutoComplete and IconField are not composable. We should be able to combine any React component with any other component seamlessly.

Looks like the IconField just blindly puts the iconPosition on all child elements.

<div {...rootProps} ref={elementRef}>
                {Children.map(props.children, (child, index) =>
                    cloneElement(child, {
                        iconPosition: props.iconPosition
                    })
                )}
            </div>

To let you know, I used IconField without autocomplete and I also have the bug.
It was working in v10.8.0, but not in v10.8.3

+1 my team and I are encountering this bug as well. We were using v10.7.0 and updated to v10.8.3 and both versions have the issue, which makes me think it was not this commit 2bc9397 from @gcko.

If someone can provide some points on how to proceed I'm happy to take a stab at fixing the issue and opening a PR.

Well as i stated the code is right here:

primereact/components/lib/iconfield/IconField.js

Lines 30 to 40 in 3dec07f

	return (
	<div {...rootProps} ref={elementRef}>
	{Children.map(props.children, (child, index) =>
	cloneElement(child, {
	iconPosition: props.iconPosition
	})
	)}
	</div>
	);
	})
	);

Its blindly putting that field on ANY child not checking that its of a certain type.

@melloware I don't follow. We were also getting the error message while using v10.7.0, which was before the commit in August that introduced that code, which suggests that that snippet is not the culprit.

[melloware]

That code is only in two places IconField and InputIcon so its coming from one of those two spots...

Any update on this? We still have this issue on:

react: 18
primereact: 10.9.1

[Bastek333]

Still issue exist on

React 19
PrimeReact 10.9.2

I am also experiencing this issue.

• React: 19
• PrimeReact: 10.9.2
• Next.js: 15.1.7

The warning appears even after removing iconPosition from my code. Is there any update on this issue?
