Hi again,
Some weeks ago I found out the
solution to this issue, I hope it can be helpful to someone.
I coded the solution creating a new XHTML
field in the main data source, and throwing an OnAfterChange event In thee
original field (secondary data source). In this function I used this code:
var answDiv = "<div xmlns=\"http://www.w3.org/1999/xhtml\">" + xmlString+ " "</div>";
var ansXMLDoc = XDocument.CreateDOM();
ansXMLDoc.loadXML(answDiv);
node.appendChild(ansXMLDoc.documentElement.cloneNode(true));
