Description

After compiling a data asset blueprint, attempting to open the parent data asset will crash the editor.

From licensee: This is because in FAssetEditorToolkit::InitAssetEditor() the objects in ObjectsToEdit that are passed into a lambda `.IsEnabled_Lambda([ObjPtrsToEdit]()` and when it's called the object was collected. Using an array of TWeakObjectPtr (instead of UObject*) makes it possible to check if the object has been destroyed and the crash can be avoided.

Steps to Reproduce

Steps using attached example project:

  • Open DataAsset
  • Open DataAsset_Parent (while keeping DataAsset open)
  • Compile DataAsset_Parent
  • Select DataAsset editor tab, and observe editor will crash

 

Steps to repo without using attached example project:

  • Create a new primary data asset
  • Create a new data asset that is derived from the new primary data asset
  • Open data asset and its parent (primary data asset) in the asset editor
  • Compile primary data asset
  • Select data asset tab
