I have a 2 workflows that when I open them in the Workflow Designer (10.4.2.246) and click the Validate button, the validation works correctly. I can see the progress window run through all the different activities to validate them.
If I click it again, it comes up for a second or two and then disappears without fully validating the workflow.
I can verify this by also removing a value from the ‘Retrieve Business Process Variables ’ activity in which I know that token is used in a Find Entry activity further in the workflow. I can remove the variable, validate the workflow and the first time it works.
If I validate it again, it does not come back with anything wrong.
I am guessing this is a bug and hope it is fixed in a newer version of Workflow.
