I ran into the same problem and converted all my DispatchActions to Actions. The downside is that there are more class files, but the mappings seem cleaner, especially in handling the 'input' attribute for <html:errors />.
Also, using Actions lets me specify different values for the 'validate' attribute. For example, I use the same form to lookup a records as I do to update it. In the case of the lookup, the Action pulls an identifier from the DynaActionForm that doesn't need to be validated (validate=false for this mapping). In the case of the update, full validation of all fields is required, so validate=true for this one.
