Can i use data class in dynamic route ?

// pages/users/user/posts/Post.kt
@Page("/users/{user}/posts/{post}") // Or @Page("/users/{user}/posts/{}")
@Composable
fun PostPage() {
/* ... */
}
Here post and user will be data class . Or do i need to pass id then convert to data class manually ?

Technically, those values will just be string values, extracted from the URL typed in. So if you use something like kotlinx serialization, you could technically encode a class inside the URL. I'm not sure I'd recommend it.

I think it will look a lot cleaner if you keep {user} and {post} to simple values and then look up data using them.

Thanks for your answer . One more question . I tried building simple kobweb project from scratch . I succeed at first project . But in my second attempt whenever i tried to appy kobweb.application plugin it throws Null pointer Exception ( no error message ) . It fixes after some gradle task i ran but i didn't find the reason for this error .

Unfortunately, I'm not sure how to help you there. I haven't seen an NPE myself and this is the first report I heard about this. If you find a way to repro this consistently, please let me know!
