Expression Validation

Expression Validation

The Workflow Manager validates all expressions in the workflow. You can enter expressions in the Assignment task, Decision task, and link conditions. The Workflow Manager writes any error message to the Output window.
Expressions in link conditions and Decision task conditions must evaluate to a numerical value. Workflow variables used in expressions must exist in the workflow.
The Workflow Manager marks the workflow invalid if a link condition is invalid.
