Jacob,
If I understand your question correctly, you have value 'A' and value 'B' but you need to pass 'AB' to the task container.
A couple ways to do this, that I know of:
- Use a programmed binding.
- Create a separate step, before the step we are talking about, with its own task that does the concatenation and passes back the value to your workflow container. This means that you have to write code somewhere to do this. I would try writing as generic a utility method as possible.
I don't do much workflow lately so there may be an easier way, but as I recall this is what I came up with for choices when I needed two values concatenated. It boggles my mind a little that there is no concatenation operator to be found in the workflow builder. (Kind of like it boggled my mind when I first started doing ABAP and found out I had to actually type out CONCATENATE.)
I hope this is helpful.
