NullPointerExcpetion in Parse Excel to CDT Plugin

Hi,

I am using "Parse Excel to CDT" plugin to parse excel.I added some rows and deleted some row by "clear the content" instead of deleting entire row.So the plugin is considering those rows and tries to parse.As a result am getting NullPointerException as below.

Problem:  An error occurred in executing an Activity Class.

Details:  java.lang.NullPointerException

Recommended Action:  Examine the activity class to correct the error and then resume.

Is there any way to handle null entry in the "Parse Excel to CDT" plugin?

Thanks in Advance!!!!
