@ -15,11 +15,3 @@ Changes to standard FESI distribution (1.1.4) for Hop
ESNumber.
- Made EcmaScriptFunctionVisitor recognise thisObj - Functions are now assigned
to the current thisObject.
- Added setPrototype() method to FESI.Data.ESObject to be able to manipulate
the prototype after the object was created.
- Changed FESI.Interpreter.EcmaScriptEvaluateVisitor to use .equals instead of
== in equal method for helma.framework.core.ESNode objects, since different
wrappers may wrap the same object.
- Added RequestEvaluator reval field to FESI.Interpreter.Evaluator in order to
let ESLoader crate wrappers with correct prototype for path element objects.
