Anyone have a creative solution for adding a cancel button to a start form that

I feel that having a cancel button that starts a process instance for no good reason is very wasteful. I felt fairly sure it wasn't possible, but I know there are a lot of Appian practitioners that hack the product and was wondering if they've run into this type of requirement.

We have the same feeling, but for Related Actions we just set the model to delete instantly upon completion so no memory resources are spent.

+1 for csteward! Easy, and it uses OOB functionality.

After years of upgrades with dozens of customizations, we are doing everything we can to replace them with OOTB functionality. I should also mention that out of habit we are using the Delete processes setting at 1 day after completion, vs 0. Back in Appian 5-6 or so this was the best practice, I forget exactly why but I think it was related to sub processes that were set to delete after 0 days would cause issues - maybe someone from Appian staff could chime in on that one.

I know this is not related to the main topic of this post but since it was mentioned I thought I should clarify.

The recommendation mentioned above of deleting the process after 1 day instead of 0 days is only to prevent race conditions with sub-processes that update variables from the parent "by-reference". This is to make sure the change is pushed to the Analytics engine too before the sub-process gets deleted from the exec.
