Project Efforts export to CSV


version: 0.0902
Projects > [project_name] > Efforts

I have added one record for [project_name] with duration 4 hours
In front-end list i can see duration of 4 hrs
When i click on Export as CSV, file "projViewEfforts.csv" gets generated
In this file, column as_duration is blank and on next line i get the text: <input type="hidden" name="prj" value="8012">

When i add more than one efforts, then exported csv file contains as_duration = 1 and again last record has the same problem.... as_duration blank and on next line: <input type="hidden" name="prj" value="8012">

I can not see exact effort duration here. Is it possible to implement this addon while csv export? i.e. One additional column for exact effort duration.
