[xwiki-users] Howto getprefix in a Sheet?

Hello,I have a docClass with some properties and use a linked Sheet to display my data.On this thread http://xwiki.475771.n2.nabble.com/Help-with-custom-display-td508630.htmlI saw we can get this value in "custom display" field of docClass properties.- $name = the name of the displayed field - $prefix = a prefix for the form field - $object = the displayed object - $type = the intended display mode (view, edit, hidden, search...) - $value = the property value I try to have same value from mydocSheet (in particulary prefix the id of the field in edit form) There Velocity code in my docSheet: #set($class = $doc.getObject('MySpace.docClass').xWikiClass) #foreach($prop in $class.properties)   * "$prop.Name"  * $prop.?????? How to obtain the prefix ???  * $object (it doesn't matter)  * $xcontext.action  * $doc.getValue($prop.Name)   $prop.prettyName $doc.display($prop.getName()) #end #break If any have an (or many) idea how I can obtain this prefix in my Sheet (If not I can concanet MySpace.docClass_0_$prop.Name but I'm not sure about _0_) Thxs Pascal B
