This issue deals with the fact that in the current syntax the Invoke activity requires a partnerLink and a portType. However the partnerLink refers to a partnerLinkType, which also includes the portType. Therefore the portType in the Invoke is redundant. So far, there is no disagreement on this analysis. There are two possible solutions (or proposals): 1- (proposal 1): Just remove the portType from the invoke activity and use the portType that corresponds to the partnerRole in the partnerLink. This covers most if not all the use cases. With the only exception of a process that wants to call itself, in which case you will need to create another partnerLink (using the same partnerLinkType) and use it instead. So, in this case you end with two partner links. 2- (proposal 2): Remove the portType from the invoke activity, but add an optional role. When the role is specified, it must correspond to one of the two roles defined in the partnerLink. If the role is not specified the partnerRole in the partnerLink should be assumed. With this second proposal, in most cases the syntax will look exactly the same as with the first proposal. But, if a process needs to call itself, instead of adding a partner link, it just adds a role to the invoke activity. Both solutions are similar and better than the current syntax. The only real difference is the optional role on the invoke activity to preserve the functionality currently specified, but that seems to be uncommon. Regards, Mike Marin
