title: How to add new dialog on workflow transition in Jira
body: <p>I want to make a jira plugin that works like a workflow validator, but instead of not allowing a transition if certain conditions are not met, I want to just bring up a warning dialog where the user can choose to continue or cancel the transition.</p>
  
  <p>As far as I can tell this is not possible using a workflow validator, as that will only bring up an error if the conditions are not met.</p>
  
  <p>I have written webwork plugins before, and that would seem like one likely possibility, but I don't know how it would be possible to intercept the workflow transition to perform the custom action.</p>
  
  <p>I don't know if what I want to do is possible at all, and if it is, I don't know if a webwork plugin would be able to do it.</p>
  
  <p>Are there any Jira experts out there who could point me in the right direction?</p>
  
  <p>Thanks,<br>
  Marcus.</p>
