More of a "What the heck?" question... In WWF 3.0 I had a nested state (actually a couple of levels deep) and added some event driven activities. Then when compiling I noticed that I was getting warnings about that state not implementing some of the service operations defined for the parent workflow. The ops are implemented in the parent states. And warnings for other nested states at the same level were not getting generated. Huh? Looking at the XOML, I saw that the state generating the warnings had this node defined:
<ns0:ReceiveActivity.WorkflowServiceAttributes>
<ns0:WorkflowServiceAttributes />
</ns0:ReceiveActivity.WorkflowServiceAttributes>
I don't know what I did to cause this to be inserted, but I found that removing this node eliminated the warnings. So thought I'd post this in case others encounter it or if someone has some insight into this. Thanks,
