I defined some aspects. I attached these aspects to my documents. I've the necessity to show different properties with a different layout when I want to see the properties associated to a document in "edit-mode" or "view-mode". Is it possible?
If you go look at the out-of-the-box form configuration ($TOMCAT_HOME/webapps/share/WEB-INF/classes/alfresco/share-form-config.xml) you will see an example of the use of the "for-mode" attribute on the "show" element.
