Application area issue, analyzer warning AD0001 - Rule189ApplicationAreaHasInvalidValue

[linasostreika]

Hi,

We found ourselfves in situation where we receive a warning from analyzer with ID AD0001, which shouldnt be considered as warning.

We have a field obsoleted on Application Area Setup extension:

tableextension 17031631 "S4LA Appl. Area Setup Ext." extends "Application Area Setup"
{
fields
{
field(17021801; "S4LA Leasing"; Boolean)
{
DataClassification = CustomerContent;
Caption = '(Obsolete) S4Leasing';
Description = 'S4Leasing new Application area';
ObsoleteState = Removed;
ObsoleteReason = 'SL63 replaced by another field S4LALeasing';
ObsoleteTag = '63.0.0.0';
}
field(17021802; S4LALeasing; Boolean)
{
Caption = 'S4LA Leasing';
DataClassification = CustomerContent;
}
}
}

Analyzer shows warning:

warning AD0001: Analyzer 'Microsoft.Dynamics.Nav.CodeCop.Design.Rule189ApplicationAreaHasInvalidValue' threw an exception of type 'System.ArgumentException' with message 'System.ArgumentException: An item with the same key has already been added. Key: S4LALeasing

The error shows the analyser is crashing. It shouldn't crash, thus marking for triage
