When building a RuleSet from within Visual Studio I'm getting an error when trying to call a method on my Workflow. I'm validating an incoming message, and need to call a method which adds additional information to the incoming message and validates various business rules. When I add a rule action which looks like:

this.AddBrokenRule(this.Request.Employee, "First Name is Required", "FirstName")

I get the following error from the rule designer:

Error Parsing the Action(s): Object reference not set to an instance of an object.

The error arises when there are overloaded versions of the associated function available. When I start building the statement, the Intellisense properly identifies the 3 overloads of the function, but it seems unable to use any of the overloads. If I rename the functions such that each has a unique name, it seems to work properly.

Thanks!

Overloaded functions do not work as expected in the ruleset editor. This is a known issue.

- Thanks

Can you let me know which version of Windows Workflow Foundation you are using.

I tried overloaded functions on Beta2 & Beta2.2 and it seems to workfine.

Can you share your code with me?

Thanks,

I am currently using Beta 2 [Jan CTP], I'm trying to put together an example which exposes the bug, but my simple examples that I've put together seem to work fine...  I'm trying to isolate what is different about the sample project vs. where I am actually seeing the bug.  If I manage to isolate the problem, I'll post reproduction steps here.

 EDIT:

And now I'm especially puzzled, because after re-opening the problem project and changing things back to how they were when the error was showing up... everything is working just fine.  If I see the issue again, I'll try to poke at it a little more thoroughly to see what causes the error to stop showing up.
