I am  writing my own gemini plugin by subclassing AbstractIssueListener.
Problem is on the method 

public override void IssueCreated(IssueEventArgs args)
{
}
the arrays
  args.Issue.IssueCustomFieldDataNH
  args.Issue.IssueCustomFieldData
have length 0 and does not contain any of my custom field values.

must I call the web service to get those custom field values?
one would expect the custom field values in place like 
in the method IssueUpdated(IssueEventArgs args).
