jBehave NullPointerException

Question

I have a parent story which calls some common stories as below;

Meta: @action_text %start_action_text

GivenStories: common/s_1.story,
              common/s_2.story#{0},
              common/s_3.story,

I am passing parameters to 3rd story s_3.story using Meta: @action_text %start_action_text and am getting an exception.

In story 3, I have step as

When I select example action <action_text> on Panel (FAILED)

This step is failing and I am getting NullPointerException
