Best way to execute a check before a transition can happen

Question

Looking for an advise to do the following:

When a JIRA transition can occur, I want to check to see if some conditions are met (i.e. the Status of the associated ticket(s) to this parent ticket are in certain Status, etc.)  Do you think implementing a groovy script and have script runner run this script and return true/false is one way?  If not, what's other way to archive this?  Thanks!

Hello Jobin, Thanks for getting back quickly.  When you mentioned other option in Java, did you mean to use ScriptRunner to call a Java program to achieve the same results?  Thanks.

That is certainly an option and nothing wrong in doing that. Other option will be to do the same thing in Java and it is up to you, depending on what you are best at - scripting or Java programming.
