unable to drop a textEdit in a TableLayout
===

I am using Android 4.2 and Eclipse indigo (3.7.0).  I created a TableLayout with 6 rows.  I wanted to add a textView and a editText in one row using the Graphic Layout in eclipse.  No problem adding textView but when I drag and drop editText, the following error is displayed:

***NOTE: This project contains Java compilation errors, which can cause rendering failures for custom views. Fix compilation problems first.
java.util.LinkedHashMap.eldest()Ljava/util/Map$Entry;***

I have not written any code yet.  Any code is generated by eclipse when I first created the project.  Does anyone has any idea where the problem is?
