Throwing error message on Website

Hello, 

when I put an throw argument in an script for the Active Roles Website it doesnt seem to display it anymore like it used to be.

Examples:

throw "something went wrong"

$Request.SetPolicyComplianceInfo("samaccountname", $Constants.EDS_POLICY_COMPLIANCE_ERROR, "bla bla, not good")

dont seem to work, when the error should be triggered nothing happens or is displayed on the website.

Is this a new behaviour or has something changed regarding displaying errors on the Website forms?

Thanks in advance.
