<p class=MsoNormal>I’m trying to setup a backoffice for my site in which
I can add a field (of simple type) to the schema defining my contents.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>My code is:<o:p></o:p></p>
<p class=MsoNormal>CmsXmlContent content =
CmsXmlContentFactory.unmarshal($cmsObject, currentResource, request);<o:p></o:p></p>
<p class=MsoNormal>CmsXmlContentDefinition def =
content.getContentDefinition();<o:p></o:p></p>
<p class=MsoNormal>CmsXmlStringValue newType = new CmsXmlStringValue(elementName,
"0", "1");<o:p></o:p></p>
<p class=MsoNormal>def.addType(newType);<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>but unfortunately the addtype raise an
UnsupportedOperationException with the following stack trace (just the
beginning, obvious):<o:p></o:p></p>
<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Courier New"'>java.lang.UnsupportedOperationException<o:p></o:p></span></p>

<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Can anyone help me? Is it possible to do such operation?
Where’s the error?<o:p></o:p></p>
<p class=MsoNormal>Thanks in advance<o:p></o:p></p>
