Writing to the Database

While editing a ClassSheet, XWiki shortcuts writing to the database with its hot-coded input fields. How can one explicitly write to the database in this context? Rather than allowing the user to type one of the property's values into an input box, I need the value to be extracted from the URL and directly written to the database as the property value for this instance of my custom class. Inserting: $doc.displayEdit($prop, "{property name}", ${the getParameter's new variable}) did not work. Any suggestions? _________________________________________________________________ Try the new Live Search today! http://imagine-windowslive.com/minisites/searchlaunch/?locale=en-us&FOR…
