How to find out mandatory fields for a given transition in the canned script

Question

i have written a canned script for auto transitioning the subissues based on parent issue status. However sometimes it fails as i am unable to find the required fields for auto-transition to occur. How can we find list of all mandatory fields in the required transtition. i want all those to display in the configuration page like we have "Fast track transition" which lists out all the parameters to be entered for the transition to take place. User can input the values and then this value to be updated during the transition

is there any api which will do this?if not is there any approach?

Hi Jayashree,

I would look at the post here by Jamie where he suggested using the code below to see what fields are used on a sscreen.

def issueTypeScreenSchemeManager = ComponentAccessor.getIssueTypeScreenSchemeManager()
def issueTypeScreenScheme = issueTypeScreenSchemeManager.getIssueTypeScreenScheme(getIssueContext().getProjectObject())
def fieldScreenScheme = issueTypeScreenScheme.getEffectiveFieldScreenScheme(getIssueContext().getIssueTypeObject())
def fieldScreen = fieldScreenScheme.getFieldScreen(IssueOperations.EDIT_ISSUE_OPERATION)
def tab = fieldScreen.getTab(0)
def fieldIds = tab.getFieldScreenLayoutItems()*.fieldId

I hope this helps.
