Hi guys,

I failed to assign any value to arrays of Objects through FFI.

Here's an example of code:

Original Java class:

public static class TypeInfo extends ElementInfo {
  public String[] superclasses;
}

Inside Fan script:

... 
info := TypeInfo()
info.superclasses = Str["someType"]  // Compiler error on this line: 
                                     // "Left hand side is not assignable"
...

Thanks!

It looks like there are two problems here:

  • Str is not implicitly being coerced to java.lang.String (Java FFI should know they are the same type)
  • Assignments to a array field are not working

This bug was caused by auto-coercion of arrays to lists inserted into the AST which didn't make sense during a field set.
