[xwiki-devs] Cannot get email value for XWikiUsers BaseObject

I got stuck with customized validation for XWikiUsers class using XWiki 5.2. I have custom sheet with validation with following code excerpt: public class PersonValidation implements XWikiValidationInterface { public boolean validateDocument(XWikiDocument doc, XWikiContext context) { // Validation result def res = true; // User settings from the session context def session=context.getRequest().getSession(); def user = context.getUser(); def userObj=context.getWiki().getDocument(user, context).getObject('XWiki.XWikiUsers'); if(true) { XWikiValidationStatus.addErrorToContext('NMPDtools.UserClass', '', '', 'E-mail is '+userObj.getStringValue('email'), context); res = false; } return res; } public boolean validateObject(BaseObject object, XWikiContext context) { return true; } } In difference with first_name, last_name, phone, etc. This method doesn't return property value. I noted, that using passed XWiki context, BaseObject is retured in difference with Object for inline scripts, where get... methods works properly. If nothing else, is there is way to get Object from BaseObject? Any suggestions ar welcome! Valdis
