      The UifBeanFactoryPostProcessor is a Spring bean post processor (http://static.springsource.org/spring/docs/3.1.x/spring-framework-reference/html/beans.html#beans-factory-extension-bpp) that is used to handle expressions defined in beans. These are special property values that contain the @


      syntax that the UIF framework uses to evaluate conditional statements. These are allowed for any property type (string, boolean, integer). However, Spring does not know how to handle them. So when spring creates the objects from a bean definition and tries to set a value containing one of these for a non-string type (like boolean) an exception will be thrown (of course the string '@


      ' is not a valid boolean). Therefore we pull these expressions out before Spring creates the objects.

      Within issue KULRICE-6845, we addressed everything except nested properties and lists. Spring does not currently support this. We have created a spring issue for this (https://jira.springsource.org/browse/SPR-9552), but we are blocked from further progress until it is addressed.

        setting fix version to 2.3 so we review again in that time frame.
