Extended PageInfoProvider class & added custom values[Screenshot3]. The values are displaying without any issues but sort functionality is not working.
We added all the sort attributes that are availble in default columns like published, modified, but no luck. We got to know that data-timestamp[Screenshot2] is getting added to both published & modified columns based on that sort is working whereas in our case we just added properties for json. Is there any way wher how to add that data-timestamp or any other way to make sort work.
downloaded the package from Github & installed it, still facing same issue. In that package its displaying as Calendar object [Screenshot4] coz from service they are sending Calendar object. We tried adding the sort attributes that are available for published & modified no luck[screenshot5].. Is there anyway to find how they are adding data-timestamp for published & modified columns so that we can take it up..??
