Slick-grid libraries loads when an instance of query tool is opened. But sometimes it throws exception "jQuery is not defined" and it doesn't opens up.
Solution:
As per my understanding, In datagrid/index.html file, we set the order of loading libraries such as
but it still loads pgadmin.sqleditor.js file before jQuery for unknown reason.
To fix this, we load pgadmin.sqleditor.js file using require([], function(){}) module loader which ensures that the code within function(){} will be executed when pgadmin.sqleditor.js is loaded.
