[protege-discussion] question about web protege layout configuration

Hi Jack,

Thanks for your reply.

Actually I add the new tab by checking the example of ICD project and 
copy the "change history" part with minor modification. The part I added 
to the configuration file are shown below:

..... (Individual tab)
    <label>Change History</label>
      <controllingPortlet reference="../columns/column/portlets/portlet" 
....... (Notes tab)

The title of the 'change portlet' changed when I navigated to different 
entity in the class Tab. The issue is the changes I made of the entity 
didn't shown and not indicate there is changes made in the class 
portlets. The changes I made is the definition and annotation property 
of a class. I am wondering  whether this kind modification will be 
recorded or the change of classes will be automatically recorded if 
there is annotation projected associated with the ontology project.

I did go through the webprotege layout wiki page:

However, I cannot find which portlets can be used in which predefined 
tab. Another thing, using the predefined Tab, it looks like you still 
need to define where and which portlets you would like to add, right?

Thanks again for your help.
