svn commit: r923936 - in /myfaces/core/trunk/api: pom.xml src/main/java/javax/faces/validator/BeanValidator.java src/main/java/javax/faces/validator/_BeanValidatorUELUtils.java

Author: lu4242
Date: Tue Mar 16 18:57:09 2010
New Revision: 923936

URL: http://svn.apache.org/viewvc?rev=923936&view=rev
Log:
MYFACES-2565 BeanValidator throws Exception if external ExpressionLanguageFactory is being used (fix class loading issue) and MYFACES-2605 java.lang.LinkageError loader constraint violation: loader (instance of org/mortbay/jetty/webapp/WebAppClassLoader) previously initiated loading for a different type with name "javax/el/ExpressionFactory" (wrong maven dependencies)
