svn commit: r775087 - /myfaces/orchestra/trunk/sandbox/src/main/java/org/apache/myfaces/orchestra/dynaForm/jsf/component/DynaConfig.java

[sk...@apache.org]

Author: skitching
Date: Fri May 15 11:24:35 2009
New Revision: 775087

URL: http://svn.apache.org/viewvc?rev=775087&view=rev
Log:
Allow an od:dynaFormConfig tag to specify a ComponentHandler name. The ability to set a ComponentHandler already exists via the
@ComponentHandler java annotation; this allows it to also be set via a tag.
