Hi all,  
I´m having a strange problem in my rails app hosted on Tomcat:  
The ‘div’ element which stores the validation errors of a model doesn´t  
seem to be ‘refreshed’ after each request,so I end up with the following  
problem:

In the first request:‘5 problems ocurred’  
In the second request:‘10 problems ocurred’

and so on…

Can someone spot what could be the problem?  
Thanks,  
Rafael R.

Are you updating that DIV with javascript?

No,I´m not.

I´m just putting \<%= error\_messages\_for :my\_model%\> in all the views  
that requires validation…

I think I know where the problem is:

For some reason(not worth mentioning) I have to validate the model as  
follows:

errors.each do |error|  
@model.errors.add\_to\_base(error.to\_s)  
end

so I think the ‘errors’ attribute isn´t being cleared after each  
request.How could I do this?

I tried to make:  
@model.errors.clear

but no effect at all…
