Prefixing @EpoxyAttribute variable with "is" causes compile error

Not sure what’s going on here.

I’m creating my models in Kotlin and have an attribute as follows @EpoxyAttribute var isChildComment: Boolean = false

This causes a compile error in the generated class error: isChildComment() in VideoCommentModel_ cannot override isChildComment() in VideoCommentModel public boolean isChildComment() { ^ overridden method is final

If I change the attribute to the following, the compile error is resolved @EpoxyAttribute var childComment: Boolean = false or @EpoxyAttribute var ischildComment: Boolean = false

In your original version the equivalent bytecode is

public abstract class Test extends EpoxyModel {
   @EpoxyAttribute
   private boolean isChildComment;

   public final boolean isChildComment() {
      return this.isChildComment;
   }

   public final void setChildComment(boolean var1) {
      this.isChildComment = var1;
   }
}

kotlin makes the getter final

Epoxy’s generated model creates a getter for each attribute though, which calls the original model’s getter. In this case epoxy’s generated method has the same name for the getter, which is only the case for booleans.

the bytecode with jvm field is

public abstract class Test extends EpoxyModel {
   @JvmField
   @EpoxyAttribute
   public boolean isChildComment;
}

so the field is accessed directly.

you can explore the generated kotlin bytecode and the generated epoxy model code to understand it better.

Whether it’s a bug or not, well, epoxy could be changed to not generate a getter if one already exists, but it’s not a high priority

If you add @JvmField to the field, that error should go away.

For some reason, we have issues with boolean values and epoxy attribute as well.
