NullPointerException AbstractExtendedTableRenderer

[eugenbesel]

hello all,

I implemented extendedDataTable like in example

http://livedemo.exadel.com/richfaces-demo/richfaces/extendedDataTable.jsf?c=extendedDataTable&tab=usage

it works very well.

but if I click on header of column and try to group the data I get following error message:

javax.servlet.ServletException
     javax.faces.webapp.FacesServlet.service(FacesServlet.java:277)
     org.ajax4jsf.webapp.BaseXMLFilter.doXmlFilter(BaseXMLFilter.java:178)
     org.ajax4jsf.webapp.BaseFilter.handleRequest(BaseFilter.java:290)
     org.ajax4jsf.webapp.BaseFilter.processUploadsAndHandleRequest(BaseFilter.java:388)
     org.ajax4jsf.webapp.BaseFilter.doFilter(BaseFilter.java:515)

root cause

java.lang.NullPointerException

after I sort one column, the group functionality works fine.

can anybody help me?

thank you.

     <rich:extendedDataTable value="#{searchModul.columnData}" var="data"
