Re: [S2] client-side validation error message duplication

[Pascal Lalonde]

If you are using Spring into your projet, this may be related to the 
beans being singletons, we had this problem in the past, we actually 
were required to call cleanErrorsAndMessages method at each prepare call.

I need to clear out previous submission attempt's error messages before
adding current submission attempt's error messages.
I appreciate any help you can provide!

I found the issue.  I was being a dodo.

The struts/xhtml/validation.js file's clearErrorMessages function
contains code to retrieve the table that stores the form.  It then
iterates over the table's rows, deleting any that has an errorFor
attribute.  In my case, the table that is retrieved is completely empty!
It turns out that my jsp file looks like this:

s:form action=save
table
s:textfield blah blah blah/
/table
/s:form

Which resulted in the generated html to look like this:
s:form action=save
table class=wwFormTable
table
tr
td blah blah blah/td
/tr
/table
/table
/s:form

The first table in the form had no rows!  Removing the empty table
elements from the jsp page fixed my issue.  I should pay more attention
when migrating from the simple theme to an xhtml theme.  :)
