@kabinpokhrel Do you have a reproduction test case? I have no idea how to reproduce this warning.

I'm getting these warnings too, but with the slider.

I'm closing the issue as it's missing a reproduction test case.

[DanielRamosAcosta]

What do you need exactly? I can give you the source code of the component or add you to the project so you can investigate the whole thing.

Thanks!

@DanielRamosAcosta My comment was for the author of this issue.
Regarding yours, it doesn't seem to be linked to the issue. Actually, it should already be solved on the master branch.

[DanielRamosAcosta]

Ok, I'll wait for next release then. Thanks!!

Seriously, I'm literally just importing the MuiThemeProvider and AppBar, and then rendering an AppBar wrapped in the MuiThemeProvider. My console looks like this...

React: 15.2.1
Material-UI: 0.15.4

[oliviertassinari]

@HoraceShmorace Are you using the latest version of react and material-ui?

[HoraceShmorace]

React: 15.2.1
Material-UI: 0.15.4

[HoraceShmorace]

I upgraded React to 15.3.1, and the errors cleared. That's a little too fresh of a version for production for my tastes, but it'll have to do.

[CodeStrumpet]

@HoraceShmorace -- thanks for the suggestion to upgrade React to 15.3.1. I was experiencing this warning and that cleared it up for me as well.

Using React 15.4 with MUI 16.7 and getting these warnings as well. Anyone have suggestions on how to fix this? Maybe downgrade to React 15.3X?

[oliviertassinari]

@caseychoiniere Looks like you are experiencing an edge case we are not aware of.

[caseychoiniere]

Thanks @oliviertassinari I'll continue to debug and try to figure out the root cause. Appreciate your response.

Link to repo that gives this issue using material-ui 0.17.3 and React 15.5.4: https://github.com/jugglingcats/material-ui-issue

Hopefully this gives fairly minimal repo and is simple to checkout and run (I tested using yarn install followed by yarn run and it worked on clean checkout).

EDIT: different issue - please ignore

[DanielRamosAcosta]

@jugglingcats This is other kind of issue. Yours is about the deprecation on React.Proptypes in 15.5, see #6577

[jugglingcats]

Thanks @DanielRamosAcosta my mistake. Will follow that issue!
