(there is no scroll bar present) In Taverna 2.1 beta 2 (soon to be released) you can pan using scroll bars. You can do this on both the workflow diagram and also in the monitoring diagram that you see when running a workflow. In Taverna 2.0 you can pan - see <http://www.taverna.org.uk/taverna-2-0/taverna-2-0-documentation/taverna-2-0-help/overview/design-perspective/graphical-editor/graphical-operation-icons/> (sorry for the long URL). It is counter-intuitive which is why the scroll bars have been added. > (2) The input values for XML splitters are stored as string constants, > and Taverna 2.0 does not have ‘set it as boring’. That has not yet been fixed. 'boring' processors didn't really work in Taverna 1.7.1 as the correct connections were not shown. We'll need user input as to what is wanted.

I agree that on the need for boring processors :-) It is in the bug-tracking system at http://www.mygrid.org.uk/dev/issues/browse/T2-620 I've added a comment that this has been requested (again) by a user. > (3) We used JAX-WS to wrap the fMRI tools.

Taverna should reflect the change in the WSDL. Stian Soiland-Reyes says he will look at this today. > (4) Finally, a question. How do I handle a list of strings as input / > output?

If you feed a list of strings into a service that is expecting a single string, then the service will be called for each string in the list.
