    SequenceTest

      As we have problems commiting SequenceTest, we could always post the new code fo rthe current svn in this topic...

          here's my version so that you can compare :-)

          package org.jbpm.pvm;

           Node node = execution.getNode();

            Tom,

            Could you please remove the current file in the svn and commit it again ? this probably solve the issues when updating this file.

            regards,
            Miguel Valdes

              tried but i couldn't delete. it was a good idea.

              i'll ping the it team again. strange cause they are normally much more responsive.
