You're issue is valid, but the reproduction is not - it doesn't change the rules after clicking the button, see the Playground.vue in PR for this issue

Saw that this was fixed in 1.1.6 but tested the same codepen as submitted now running on vuetify 1.1.8 and it still dosent work as expected. When the validation rule changes you have to type something in the input for the new validation to trigger. The excpeted behavior would be to run the validation when clicking on button and add/remove the error. @KaelWD @jacekkarczmarczyk

Check the log, computed.validation is only run once.

@KaelWD That is true but in this fixed codepen: https://codepen.io/taipeek/pen/PBEGZR in version 1.1.8 the issue is still there. Check the console output which shows what should be the expected rule when clicked on the button. However the input doesn't show the rule.

@Taipeek Exactly, this is the issue i have aswell. Can you confirm @KaelWD

[Taipeek]

@KaelWD @jacekkarczmarczyk just reminding that this issue is not solved in 1.1.11.

@KaelWD @jacekkarczmarczyk @johnleider Any updates on this issue?

[KaelWD]

No, and I don't know if it's possible with callback-based validation. This has been through several iterations and all of them caused more serious issues with much more common use cases.
