epcm navigation , acces denied

Hi everybody,

I am trying to make the navigation between two IViews, using epcm.doNavigate... with my own user it works fine, but with other users (with less roles assigned, just like the final users.) I get the following exception:

#com.sapportals.portal.pcd.gl.PermissionControlException: Access denied (Object: portal_content/com.ibermatica.centrocompetenciassap.elearning.elearning/com.ibermatica.centrocompetenciassap.elearning.elearning_pages/com.ibermatica.centrocompetenciassap.elearning.page_elearning_mostrarinfo)

does anybody knows where is the problem? thanks
