Problems after changing data types and containers

[Roman Weise]

Hello,
 
I changed the data type of an event parameter, added a new one and changed
the workflow and tasks definition according to the new event parameters
(workflow and task container, data handling ...). After transporting the
changes from the development to a testsystem the workflowruntime seems to
ignore these changes. The parameter with the new datatype is cut to the
old length and the new parameter which should be passed to the task
container is missing.
 
Is there the need to reset the workflowruntime and if so how can I do
this. Is it necessary to add sth. in the transport order to avoid such
problems esp. when transporting from a testsystem to production.
 
thanks in advance
