how to get the issue id or key in the context of creating a new ticket

[Manuel Joao]

Hello, i need to know how to get the issue id or key in java. Im developing a JIRA plugin that will validate fields in a new ticket screen, but i cannot retrieve the issue i am trying to retrieve custom field values in the edit screen.

You can't.  An issue will not get a key until the actual create process, which happens well after the screen.

Validators already have all the fields available during create though, so I'm not sure why you're looking for the ID.

ok so i was looking at overriding the validateFromParams method, do you think i can use that to validate custom fields on the current screen

I think i need to retrieve the values using Velocity template renderer.

The structure of a validator handles all of that for you. Start with: public void validate(Map transientVars, Map args, PropertySet ps) throws InvalidInputException, WorkflowException { Issue issue = (Issue) transientVars.get("issue");

Thanks Nic, ive got my validator plugin built now seems ok, but i will still need to retrieve a value from a custom field and compare it against another custom field value is this possible?
