Static array based on an enum does not show the enum element names

For example, I create an enum as:

UENUM(BlueprintType)
enum ETest
{
	Test_1,
	Test_2,
	Test_3,

	Test_MAX
};

And I add a variable as:

UPROPERTY(EditAnywhere)
	int32 Test[Test_MAX];

After compiling, I open the editor, Find the blueprint, I see

Before 4.26:

Test      3 Array elements
Test_1      0
Test_2      0
Test_3      0

In 4.26:

Test      3 Array elements
0              0
1              0
2              0

Hi Yql0105,

the behavior you display is expected, you’re just defining an Array with TEST_MAX number of elements.

Re: enum, first of all, use metatags!:

UENUM()
 enum ETest
 {
     Test_1        UMETA(DisplayName = "Test_1"),
     Test_2        UMETA(DisplayName = "Test_2"),
     Test_3        UMETA(DisplayName = "Test_3")
 };

Secondly, if you want to define a variable as a Enum, this is the correct way of doing it:

UPROPERTY()
TEnumAsByte<ETest> myEnumVariable;

From here this should achieve what I understand you want to achieve:

 UPROPERTY()
     TEnumAsByte<ETest> myEnumArray[MAX_ITEMs];

or even better, define that as a TArray!

Hope that helps,

There was a change in FItemPropertyNode that caused this behavior to change.

Thankfully it’s straight forward to restore. In FItemPropertyNode::GetDisplayName() around line 572 simply change this

if (FinalDisplayName.IsEmpty())
{
    FinalDisplayName = FText::AsNumber(GetArrayIndex());
}

to this

if (FinalDisplayName.IsEmpty())
{
   FinalDisplayName = FText::AsNumber(GetArrayIndex());

   if (ArraySizeEnum != nullptr)
   {
      FinalDisplayName = ArraySizeEnum->GetDisplayNameTextByIndex(GetArrayIndex());
   }
}

Oh thanks! Hope this is going to be fixed in 4.26.1!
