Hi,

I am getting following exception when i use <portlet:defineObjects /> tag in my jsp. This exception occurs only once i.e. during rendering of jsp for first time, but again when i just refresh the browser page the jsp is displayed correctly.Then the next jsps in the flow are displayed without any error.

Exception throwm:
java.lang.NullPointerException
