Double check all your beanshell scripts in that nested workflow - perhaps some of them have an if/else thing where they return a string in one case and a list in another - that would not be legal. (They would have to wrap the single string as a list as well). -- Stian Soiland-Reyes, myGrid team School of Computer Science The University of Manchester ------------------------------------------------------------------------------ Apps built with the Adobe(R) Flex(R) framework and Flex Builder(TM) are powering Web 2.0 with engaging, cross-platform capabilities.
