It seems that it was block by Static Type Checking.

If it's right.

Why it doesn't just disable other option except for String and StringName?

### Steps to reproduce

1. first select string type
2. input a text
3. change type
4. change back to string  -- it don't work
5. change to stringname -- it works
6. change back to string -- it works

### Minimal reproduction project

I think it don't need reproduction project.

						if (i > 0) {
							text += ", ";
						}
						text += args[i].get_construct_string();

					text += ")\n";
				} break;
