cannot validate.

“Simple Workflow Example Action Element Bindings,” on page 82 lists the bindings for the
vim3WaitTaskEnd and vim3WaitToolsStarted action elements.
11 Click Save at the bottom of the workflow editor's Schema tab.
The action elements' input and output parameters are bound to the appropriate parameter types and values.
What to do next
Bind the scriptable task elements and define their functions.
Simple Workflow Example Action Element Bindings
Bindings define how the simple workflow example's action elements process input and output parameters.
When defining bindings, Orchestrator presents parameters you have already defined in the workflow as
candidates for binding. If you have not defined the required parameter in the workflow yet, the only parameter
choice is NULL. Click Create parameter/attribute in workflow to create a new parameter.
vim3WaitTaskEnd Action
The vim3WaitTaskEnd action element declares constants to track the progress of a task and a polling rate. The
following table shows the input and output parameter bindings that the vim3WaitTaskEnd action requires.
