Description broy2 CLA 2011-10-17 10:49:44 EDT 
I'm on the 201110170901 install build.

Create a new RUI project which imports org.eclipse.edt.rui.widgets_0.7.0.
There are errors on TextArea, Tooltip, Password Text Field, and TextField.

IWN.VAL.6757.e 130/4 TextArea - It is invalid to assign null to the non-nullable operand backgroundColor. At line 130 in file \org.eclipse.edt.rui.widgets_0.7.0\EGLSource\org\eclipse\edt\rui\widgets\TextArea.egl	

IWN.VAL.6757.e 22/2 Tooltip - It is invalid to assign null to the non-nullable operand text. At line 22 in file \org.eclipse.edt.rui.widgets_0.7.0\EGLSource\org\eclipse\edt\rui\widgets\Tooltip.egl

This bug is happened because the language change between EDT and RBD. The compiler  may just add support for the changes, so that compile error is shown.

Verified in 20111018 build.

Ji Yong,

I made similar changes in my own workspace (e.g. convert 'null' to ""), but I did not have a chance to test the runtime behavior in all browsers.  When 'setReadOnly' is invoked for these 4 widgets, does setting the background to "" instead of 'null' have the same behavior at runtime?

I test in IE 6/7/8,9, FF 3.6/7.0 and chrome, the behavior is the same.
