Modified files:
core/src/java/org/jahia/services/webdav/listeners
CMSSlideContentListener.java
Log:
Implemented possibility to set extra field values, that can even use JEXL
expression to access all the data on the ParamBean, such as the user's name, a
user's property, the siteID, the pageID, etc...
Note : this is a reduced paramBean object that doesn't contain everything.
Notably the request and response objects are not available, so this also means
that the compose*Url methods won't work.
