filterUrlParams property not generating ajax url param on admin grid

Question

i m struggling with an issue on Magento 2.4.5 creating a custom module on admin. I have created a 2 column ui with a form and listing, which renders a grid on the admin, however, no matter what i have tried, i m not able to pass the initial url param i.e. entity_id/1 to the ajax request of the grid. I have used filter_url_params attribute on my xml, but still doesn't seem to have any affect on it.

My code looks like this

xxx_form.xml

 <insertListing name="XXXX_YYYY_item_listing" component="Magento_Customer/js/form/components/insert-listing">
 <settings>
 <dataLinks>
 <exports>false</exports>
 <imports>true</imports>
 </dataLinks>
 <externalProvider>XXXX_YYYY_item_listing.XXXX_YYYY_item_listing_data_source</externalProvider>
 <selectionsProvider>XXXX_YYYY_item_listing.XXXX_YYYY_item_listing.XXXX_YYYY_item_listing_columns.ids</selectionsProvider>
 <autoRender>true</autoRender>
 <dataScope>XXXX_YYYY_item_listing</dataScope>
 <ns>XXXX_YYYY_item_listing</ns>
 <exports>
 <link name="entity_id">${ $.externalProvider }:params.parent_id</link>
 </exports>
 <imports>
 <link name="entity_id">${ $.provider }:data.entity_id</link>
 </imports>
 </settings>
 </insertListing>

listing.xml

<listing>
 ...
 <dataSource name="XXXX_YYYY_item_listing_data_source" component="Magento_Ui/js/grid/provider">
 <settings>
 <filterUrlParams>
 <param name="entity_id">*</param>
 </filterUrlParams>
 <storageConfig>
 <param name="indexField" xsi:type="string">entity_id</param>
 </storageConfig>
 <updateUrl path="mui/index/render"/>
 </settings>
 <aclResource>XXXX_YYYY::YYYY</aclResource>
 <dataProvider name="XXXX_YYYY_item_listing_data_source"
 class="XXXX\YYYY\Ui\Component\Listing\DataProvider">
 <settings>
 <requestFieldName>entity_id</requestFieldName>
 <primaryFieldName>entity_id</primaryFieldName>
 </settings>
 </dataProvider>
 </dataSource>
 ...
</isting>

The generated url looks like this

https://magento2.localhost.com/admin_1qmg8u/mui/index/render/key/873ebb66c3e249554d98becb8e6242feebfa6231878f6013e987659ee02bdd66/?namespace=XXXX_YYYY_item_listing&sorting%5Bfield%5D=entity_id&sorting%5Bdirection%5D=asc&filters%5Bplaceholder%5D=true&paging%5BpageSize%5D=20&paging%5Bcurrent%5D=1&isAjax=true

while it should look like this

https://magento2.localhost.com/admin_1qmg8u/mui/index/render/key/873ebb66c3e249554d98becb8e6242feebfa6231878f6013e987659ee02bdd66/?namespace=XXXX_YYYY_item_listing&entity_id=1&sorting%5Bfield%5D=entity_id&sorting%5Bdirection%5D=asc&filters%5Bplaceholder%5D=true&paging%5BpageSize%5D=20&paging%5Bcurrent%5D=1&isAjax=true

Answer 1

Finally found the answer. The problem occured since in the form, in order to prefill the fields i had used an extra key in the data provider, resulting in having to modify the import tag as following

 <exports>
 <link name="entity_id">${ $.externalProvider }:params.parent_id</link>
 </exports>
 <imports>
 <link name="entity_id">${ $.provider }:data.MY_DATA_PROVIDER_KEY.entity_id</link>
 </imports>

• Egi: can you give example MY_DATA_PROVIDER_KEY ?
