[youtokyo4gf5c2]

I am trying to get request param id when edit page in my component dataprovider file. But getting always null value in it.

I am rendering grid in product edit page and i need to filter my data based on current edit page.and when i try to click on tab it fire mui/index/render action and not getting product id in it.

I have also tried using this code (int)$this->request->getParam('current_product_id'); but it is also returning empty value. can anyone please guide on this.

Replace the below code in the custom modifier class' array of config.

'imports' => [
    'productId' => '${ $.provider }:data.product.current_product_id',
    '__disableTmpl' => ['productId' => false],
],
'exports' => [
    'productId' => '${ $.externalProvider }:params.current_product_id',
    '__disableTmpl' => ['productId' => false],
],
