I've upgraded to 7.6.0. Some of my query's don't work now, like this one:

@{ var selection = CurrentPage.Children.Where("statusPercentage < 100"); }

The statusPercentage is a slider. I've also tried the new Query Builder because the result differs a bit in syntax. The builder itself only gives me the standard fields, not the custom field like statusPercentage in my exemple. I added that myself:

@{
    var selection = Model.Content.Site().Children("project")
                        .Where(x => x.IsVisible())
                        .Where(x => x.statusPercentage < 100);
}

But that also won't work.

The second query that doesn't work is this one:

var selection = root.Descendants("photosItem").Where("Gear.Contains(\"" + @CurrentPage.Id + "\")").Where("Visible").Random(5);

The field "gear" is a multiple content picker. It should return all photosItem's with one of the pages in that 'multiple content picker'-field is the current page. I read about the EnablePropertyValueConverters-setting, but I prefer to use the new way instead of the legacy-method.
