To remove the window state buttons you can set the windowrenderer to emptyrenderer. | <window> | <window-name>MyPortletWindow</window-name> | <instance-ref> | MyPortletInstance | </instance-ref> | <region>center</region> | <height>1</height> | <properties> | <!-- turn the decoration off for this portlet (i.e. no title and mode/state links) --> | <property> | <name>theme.decorationRendererId</name> | <value>emptyRenderer</value> | </property> | <property> | <name>theme.windowRendererId</name> | <value>emptyRenderer</value> | </property> | </properties> | </window> | As for the original issue, I tried digging into the source code, The request dispatcher seems to be returning null for the getMarkup() method if the TargetContext is anything other than portal-core.
