Struts2 conversion warning

Question

I am developing a model based web application on Struts2.2.3. What I mean by model is, database tables are represented as java classes(you know). And models have properties with types such as Integer, Date and so on. When I render these values on page, and when user puts values other than it is original type, it always giving me exceptions. It is not reaching validation function before getting populated.

And it shows following message on page:

Invalid field value for field "estimates[1].count".

Also shows following exception on console

 WARN OgnlValueStack:60 - Error setting expression 'estimates[1].count' with value '[Ljava.lang.String;@a61ffd'

I saw several people had this issue before like this: http://osdir.com/ml/user-struts.apache.org/2009-12/msg00037.html

I have my ConversionError interceptor removed from my default stack. And my devMode is off. However, I am still getting these errors.

UPDATE:

I found that error exception can be caught by MyAction-validation.xml and error message can be customized. But OGNL warning still remained.

Thus the question is:

Is there any way not to show this warning on log?
