Hi, when I have two instances of a composable with FilledTextField, I'm getting this error:

Any thoughts?
Thanks 🙂

hey. it is the same issue as here https://kotlinlang.slack.com/archives/CJLTWPH7S/p1593084208100000?thread_ts=1593084208.100000&cid=CJLTWPH7S

hey, so the FilledTextField component is affected by that and I would need to duplicate FilledTextField and add the work around until it's fixed?

[Andrey Kulikov]

no, you don't need to duplicate it. you have for loop somewhere and you need to add key(index) {} inside the for loop. we will make it more automated in the future. if it is still not clear I can help if you share a bit of your code

Oh thanks it's working now 😄 I was using a "u"id associated with the object in the for loop but I was sillily using a new random object with the same seed for each id 🙃

Would you recommend it is still better to use the for loop indices ?

[Andrey Kulikov]

yes, indices are better, if you don't have anything other unique

[Andrey Kulikov]

in next releases it will be working automatically as if you used indices

ooo great work 😄
