There is no support for tracking services. Or rather, if there is, nobody is saying. You’re stuck with ‘History’ lists, which suck. All I want is a table I can query, and that I’ll expose that via the BDC. But without this, workflow in SharePoint is nothing more than a toy, which isn’t fair given the effort put into it. I know that Microsoft don’t want to step on K2′s toes – fair enough. Truth be told, I was wondering what K2 were going to do, figured that they must be running scared – but having seen Black Pearl, I see that they’ve been running hard, and have a good lead. A SQL tracking service won’t erode that lead.

Repeating fields in Infopath forms are unusable. Nobody knows how to do this. I spent ages working on it, but I didn’t get anywhere. I couldn’t write to these properties through the task properties at all. Indeed, the whole TaskChangedProperties.ExtendedProperties hash is daft. Forcing everything to flatten, well, sucks. Can’t I have a stream? Or a node-child tree of some sort? I mean, is it surprising to want to send InfoPath forms to/from a workflow task and a library? You know, use the workflow for routing, and the xml form in a library as the data store? That should be easy – it’s not.

Debugging workflows is hard. I mean, apart from Visual Studio crashing as I connect it to the appropriate service, there is a question over actually being able to get meaningful error messages out of workflow, and getting it able to breakpoint in the right places. In fairness, this is a complex thing. I have no idea how I’d set about allowing debugging in Visual Studio, say, after a Delay activity had expired. But it would be cool to have something a bit better.
