Creating a portlet clon in LifeRay

Some times we need a copy of a existing portlet, like navigation, breadcrumb, etc. We can do a copy of some portlet to instance it in the theme and have two different portlet configurations for the same type of portlet. This are the steps that we have to follow:

1. Edit liferay-display.xml and add a free id entry for that portlet.

2. Edit liferay-portlet.xml. We can copy the "..." of the origin portlet, and asign the free id of point 2.

3. Edit portlet-custom. We do the same of point 3.

4. Finally, we give a title to the portlet. Create a file in“/portal/WEB-INF/classes/content” called Language-ext_en_US.properties and add the line:
javax.portlet.title.FreeId=My_Clon_Portlet
