Re: How to add more internal node properties
Posted by lixin chu <li...@yahoo.com>.
I just tried - I wanted to add a 'accessTimes'
property:
public void create (ContentEvent event) {
// create a new node property
NodeRevisionDescriptor revision =
event.getRevisionDescriptor();
if (revision != null) {
revision.setProperty("accessTimes", new Integer
(0));
}
}
I can see that the new property os created in the
metadata file; then I added:
public void retrieve (ContentEvent event) {
NodeRevisionDescriptor revision =
event.getRevisionDescriptor();
if (revision != null) {
NodeProperty n =
revision.getProperty("accessTimes");
if (n != null) {
int l = ((Integer)
n.getValue()).intValue()+1;
revision.setProperty("accessTimes", new
Integer (l));
System.out.println ("accessTimes =
"+Integer.toString(l));
}
}
}
the problem is that I always get accessTimes 1 or 2
the metadata property value is not updated. anything
wrong ?
