Hi All, I guess more a question for the dev team, anyone that may know offhand otherwise ;) Searched around on the XWiki.org site with no indication of the following functionality; but cannot seem to find references in documentation at all. I've also tried to enter bits of data that seem correct (eg, a RegEx into the field at "c" does not seem to do any checks, or show any message if it fails), with no luck yet. So, hopefully can someone help me understand: a) for db lists, ID Field Name and Value Field Name indicates being able to use a different display and record value - is this correct, and if so; what is the syntax to this? b) for db lists again, there is an Xwiki Class Name field - what does this do? Entering a valid class name does not seem to alter the behaviour in any way. c) for Strings/Dates/etc there is a Validation Regular Expression (and associated Validation Message) field; is this intended as a validation expression for the field value? If so, is it active? - so far it does not give any message (provided or otherwise) when used. d) For list types, there is a new entry called Display Type - changing this does not seem to make, eg a dropdown list into an input - is this what it is intended for, and if so; what restrictions are there in the underlying code? Can a select list be changed to a text box with this field (assuming data already entered stays the same)? e) Tooltip and Custom Display: Is this an automatic field render, or must these fields be initiated in some way?
