[Building Sakai] Lessons Tool incompatible with Sakai Connector portlet

[chaitanya.cheekate]

I am using sakai connector portlet(tried both 1.4.0 and 1.5.0) to render
tools in Liferay 6.0.6 portal. I am able to render all tools. but I am
getting the following error while rendering lessons tool. FYI Lessons tool
is rendering properly in sakai environment.

Fatal internal error handling request:
Target exception of class java.lang.NullPointerException
Successive lines until stack trace show causes progressing to exception
site:
