filtering expression in richfaces datatable

[simonc2009]

Hi,

I am writing a filtering expression using xmlns:fn="http://java.sun.com/jsp/jstl/functions", within richfaces datatable.

I find below statement works if data type is string

e.g. filterExpression="#{fn:containsIgnoreCase(hot.stringtype, filteringBean.Stringvalue1)}"

But, I found problem if data type is double or date.

So, please help

Thanks
