Order by not working in list collector?

[rahul16]

What is wrong with the list collector I am unable to show data on the portal form with order by u_order field.

variable attribute - ref_qual_elements=category,ref_ac_order_by=u_order,ref_auto_completer=AJAXTableCompleter

Reference qualifier - javascript: 'u_inactive=false^u_type=subcategory^u_dependent =' + current.variables.category+'^u_catalog_item='+(current.cat_item.sys_id||current.request_item.cat_item.sys_id);

I am getting the data based on the category selected. but order is not working

For category data coming by order by but for subcategory data is not coming in order

Can you try to remove orderby from category to check any change in data, we need to check if orderby is working or by default the category data is showing in that order.

Before orderby it not showing in order. after adding it showing based on the order.

I try with variable attributes but it's not worked so I added orderby it working fine.
