The following code example will generate category rows with nullptr assigned to OnPasteFromTextDelegate which causes a crash if the user tries to paste onto a row.
Once you have this code create the "CopyPasteExample" component on an actor, assign Foo to UCopyPasteCrash. This will create two category rows: UCopyPasteCrashBase and UCopyPasteCrash. If you try to paste into either of these you will crash.
#pragma once #include "CopyPasteCrashExample.generated.h" UCLASS(Abstract, EditInlineNew) class UCopyPasteCrashBase : public UObject { GENERATED_BODY() public: UPROPERTY(EditAnywhere) int32 A; }; UCLASS() class UCopyPasteCrash : public UCopyPasteCrashBase { GENERATED_BODY() public: UPROPERTY(EditAnywhere) int32 B; }; UCLASS(meta = (BlueprintSpawnableComponent)) class UCopyPasteCrashExample : public USceneComponent { GENERATED_BODY() public: UPROPERTY(EditAnywhere, BlueprintReadWrite, Instanced) TObjectPtr<UCopyPasteCrashBase> Foo; };
There's no existing public thread on this issue, so head over to Questions & Answers just mention UE-228826 in the post.
