So I have a ticket on this right now but want to see if anyone else has done this. We have a client that emails a vendor when they have an issue with an invoice. Some vendor's have more than one email address. In the workflow I have a webservice that grabs all of the emails for that client and puts them in a variable. Some vendor's just have 1 email address while others have 3-5. I can see that the email addresses are being added to the variable, with semi colons separating each value (firstname.lastname@example.org; email@example.com; firstname.lastname@example.org;) etc... However when I assign the variable to the "To" box in an email step I get an error stating "No recipeints found in activity with definitionID".
Does anyone have a trick to doing this without making a loop with several arithmatic rules?
