Remove "change comment"
When I edit my document I see the “Change comment” text area, is there anyway not to show it? My document doesn't have any facets.
If you speak about the 'Comment' text area in the edit tab, you should remove it simply by overriding the template document_edit.xhtml (in nuxeo.war/incl/tabs) by your own file.
You just need to comment lines below:
<table class="dataInput">
<tbody>
<tr>
<td class="iconColumn" style="vertical-align:top;" />
<td class="labelColumn">
<h:outputText value="#{messages['label.comment']}" />
</td>
<td class="fieldColumn">
<h:inputTextarea value="#{currentDocument.contextData['request/comment']}" />
</td>
</tr>
</tbody>
</table>
Else if you don't want override the default template a proper way IMO is to create your own layout (see http://doc.nuxeo.com/display/NXDOC/Layout+display) like this you keep the default behavior when you upgrade your version of Nuxeo.
