{% stackoverflow 57919749 %}

I'm getting an error in the title. Application I also have a mixed structure and use a few nested structures.

There is a structure like <b>" CategoryFragment -> ViewPager -> RecyclerView inside CategoryDetailsFragment -> ViewPager-> HeadlinePagerFragment"</b>

when changed to CategoryFragment then return to back will be this error.



- CategoryFragment 

```kotlin
val adapter = CategoriesPagerAdapter(activity?.supportFragmentManager!!,list as List<MutableMap<String,String>>)
vp_categories_pager.adapter = adapter
tl_categories.setupWithViewPager(vp_categories_pager)
```
- CategoryDetailsFragment
This class use recyclerview and usage inside of childview viewpager.

```kotlin
rv_category_details.adapter = ContentAdapter(
            context!!,this@CategoryDetailsFragment(usage as fragment),
            this@CategoryDetailsFragment)


```

-> Adapter
```kotlin
 vp_headline.adapter =HeadlineAdapter(
                            fragment?.childFragmentManager!!,
                            items, itemClickListener)
                    tl_headline_indicator.setupWithViewPager(vp_headline)
```

- HeadlineAdapter

```kotlin
class HeadlineAdapter(
    fragment: FragmentManager,
    var list:MutableList<MutableMap<*,*>>,
    val itemclickListener:ContentAdapter.Itemclicklistener)
    :FragmentPagerAdapter(fragment){
    override fun getItem(position: Int): Fragment =
        HeadlinePagerFragment(PutData(mutableMapOf(
        'm' to list[position],
        'l' to itemclickListener
    )))

    override fun getCount(): Int = list.size

    override fun getItemPosition(`object`: Any): Int {
        return PagerAdapter.POSITION_NONE
    }

}
```

Return this error 
```
