RTC Javascript validation- redundant error message is showing on save workitem.

Hi All,

I have a script to validate the dates field in my form. The validation works perfectly , but when i try to save the workitem,
i get the redundant error messages in header shown in RTC web UI as follows.

Invalid value of attribute 'Actual End Date': Actual End Date should be greater than or equal to Actual Start Date.
Invalid value of attribute 'Actual End Date' in work item '<11:18:01>': Actual End Date should be greater than or equal to Actual Start Date.

I have configured the error messages in process configuration source as follows-

<validator id="valdr1">
 <parameters message="Actual End Date should be greater than or equal to Actual Start Date.">
</validator>

is there any way to avoid this kind of redundancy in error messages? Please advice?

Thanks
