Displaying Warning Messages in Team Advisor

Hi,

I ahve the following code in my class for a follow up action to display warning messages on the Team Advisor.
This follow up action is executed on "SAve Work Item" Action ad just before saving, I call this method to add warning messages to the Collector.

private void processRequiredAttributeWarnings(
IParticipantInfoCollector collector, ArrayList<String> warnings) {
if (warnings == null)
return;

Iterator<String> warningIter = warnings.iterator();
while (warningIter.hasNext()) {
String[] warning = warningIter.next();
addWarning(collector, warning,warning);
}
}

and

private void addWarning(IParticipantInfoCollector collector, String summary,String warning) {
IReportInfo reportInfo = collector.createInfo(summary, warning);
collector.addInfo(reportInfo);
}


This code is not displaying the warning in the Team Advisor View.
Please help.
