Automatically displaying the error text for a form field when the validator fails?

Question

Hi,
Flex 2 has a very nice feature to display custom text next to
a form field whose validation failed. But the user has to move the
mouse over the form field to display the text. Is there a way to
invoke this feature programmatically?
What I would like to do is validate form fields on submit and
- if validation fails for a form field - set focus on that form
field and automatically display the custom error text in the red
blurb. Focusing works fine but I cant' get the text to render...

Thanks Bregent.
Weirdest thing...I just tried a Google search for a solution to this problem and came across another thread on this forum.  By the time I got to the bottom of it I realised one of those taking part was myself from years ago!  Jeesh, been here before or what!
Changed my recordset to...
<%
Dim rsPROP__MMColParam
rsPROP__MMColParam = "0"
If (Request.Form("categoryID") <> "") Then
  rsPROP__MMColParam = Request.Form("categoryID")
End If
%>
<%
Dim rsPROP__MMColParam1
rsPROP__MMColParam1 = "1"
If (Request.Form("categoryID") <> "") Then
  rsPROP__MMColParam1 = Request.Form("categoryID")
End If
%>
<%
Dim rsPROP
Dim rsPROP_cmd
Dim rsPROP_numRows
Set rsPROP_cmd = Server.CreateObject ("ADODB.Command")
rsPROP_cmd.ActiveConnection = MM_cs_STRING
rsPROP_cmd.CommandText = "SELECT prodid, product, categoryID FROM dbo.products WHERE ISNULL(?,0) = 0 OR categoryID = ?"
rsPROP_cmd.Prepared = true
rsPROP_cmd.Parameters.Append rsPROP_cmd.CreateParameter("param1", 5, 1, -1, rsPROP__MMColParam) ' adDouble
rsPROP_cmd.Parameters.Append rsPROP_cmd.CreateParameter("param2", 5, 1, -1, rsPROP__MMColParam) ' adDouble
Set rsPROP = rsPROP_cmd.Execute
rsPROP_numRows = 0
%>
...and it works fine.
Appreciate the help. I would have taken your advice and done an If Else on the WHERE clause to acheive the same.
Thank you.
