Flex/BlazeDS Error missing property

I have this error when run开发者_开发问答ning my application on debug mode :

ReferenceError: Error #1056: Cannot create property root on MyClass.

The problem is that MyClass doesn't contain any root property and i don't know how it get it, I have isRoot property at the Java Class with setRoot setter and isRoot methods,

at the flex side i have isRoot as public without getter and setter.... could the problem be just convention names compatibility

---

The flex property name must be root instead of isRoot.

BlazeDS is using the Java Beans naming convention. For more informations read the BlazeDS Developer Guide / Serializing between ActionScript and Java:

BlazeDS uses the standard Java class, java.beans.Introspector, to get property descriptors for a Java bean class. It also uses reflection to gather public fields on a class. It uses bean properties in preference to fields. The Java and ActionScript property names should match.
