How to ensure that the workflow transition stops when a groovy script fails in workflow postfunction

[Shreyance Shaw]

We have a groovy script in the Transition post function. 

How do i make sure that the transition only goes through if the script executes successfully ?

As of now even if the script fails the transition goes through.

You don't.

A post-function can not stop a transition (well, they can if they fail catastrophically, but that can easily leave your issue data messed up too)

You need to move the script to a validator, but ideally only one that checks that the script will run ok when it's done as a post-function (you should not update anything in a validator, only check things)

Hi Nic,

Thank you for the response.

We are to create a Confluence page during a transition, we need to ensure that the transition is done only when the page is created and remote link is established.

Is there a way to check if a Confluence page creation groovy script will run okay ?

There is no way to do that in full, but what I would do is write a script that tries to read what the page will be in a validator - if it fails to open a connection to Confluence or finds the page (you can't create pages with the same name as an existing page, so this is a good check), then fail the validator.

If it passes, then try to create the page in the post-function, and capture the result.  If you do get a failure, write more data back into the issue to tell the user the page failed to create!
