Description

Attempting to clear an array in a const function returns no compiler error in blueprints. If you create the same setup in C++ using a const function, an error is returning upon compiling as expected.

Steps to Reproduce
  1. Open the editor
  2. Create a new actor blueprint
  3. Create a new function and set it to Const in the details panel
  4. Add an Array variable to the blueprint
  5. In the function, drag off to add a Clear node
  6. Get your array variable and connect it to the Clear node
  7. Compile

Result: No compiler warning

Expected: Compiler warning would appear as you are attempting to modify a property of the blueprint in a Const function.
