Question

Workflow Empty equals Empty is False?

Workflow

Hello All,

I have a workflow that is triggered by a business process. It pulls variables from the form, then performs a SQL lookup and compares the 2 results to determine if any of the fields have changed. Oddly, I am getting an error that "[Empty] <equals> [Empty]" is FALSE, so the workflow always thinks something has changed.

Has anyone seen this before? The workflow server version is 10.2.0.216

It likely depends on the data. If one token comes back as the empty string ("") and the other is NULL, then that comparison is correct.

I have seen this before! It seems that it would be true, but it thinks that it is false. You will have to add the conditional group that both of the following are true: variable 1 is empty and variable 2 is empty.
