from https://github.com/microsoft/AL/issues/6486 - this and my support ticket via partner were closed, the latter claiming this would be by-design, but I want some more eyes on it, or at least votes indicating the 'design' is absurd ;-)


**Describe the bug**
Setting filters in group -1 where one or more of the ORd fields is a FlowField does not work (properly).

**To Reproduce**

Run the below. If need be, create a new `Customer` whose `Balance (LCY)` (a FlowField) is `0`.

Click the new `Process`/`Test` action. See that, although we verify that `Balance (LCY)` is `0`, the filter that should mean '`Name` is empty (false) OR `Balance (LCY)` is 0 (true)` does not work: the `FindFirst()` throws an error because no record is found.

Yet... We just verified that it exists.

The resulting error does not acknowledge that any filter was even set on `Balance (LCY)`:

...whereas if putting multiple Normal fields in `FilterGroup(-1)`, it would recite them all:

So clearly something is going wrong here, and the FlowField is just being ignored, not ORd.

```al
pageextension 50100 CustomerListExt extends "Customer List"
{
actions
{
addfirst(processing)
{
action(Test)
{
ApplicationArea = All;
Caption = 'Test';
Image = TestDatabase;
Promoted = true;
PromotedCategory = Process;
PromotedOnly = true;
ToolTip = 'Run the test.';

trigger OnAction()
var
Customer: Record Customer;
begin
Rec.TestField("No.");
Rec.TestField("Name");
Rec.TestField("Balance (LCY)", 0);

Customer.SetRange("No.", Rec."No.");

Customer.FilterGroup(-1);
Customer.SetRange(Name, '');
Customer.SetRange("Balance (LCY)", 0);

Customer.FindFirst();
end;
}
}
}
}
```

**Expected behavior**
FlowFields in `FilterGroup(-1)` should be ORd with the other fields. If they are not supported here, that needs to be
- documented,
- a compile-time error so that no one else wastes their time debugging and figuring out a repro for this, and
- ideally fixed later.
