Problem with f:convertNumber

[Adrian Mitev]

Hi all! I`m using myfaces 1.1.5 nightly build. I've created my own convertor for BigDecimal to show error message that is oriented to the big decimal object. I have form with input field that is binded to big decimal. Everything works fine. Now i want to put a convertor that will cut some fraction digits - <f:convertNumber maxFractionDigits="5" />. When the page is rendered everything is ok but when i submit the form i got the following as <h:message> for the input component:
Exception setting property taxBase of base with class org.cts.web.bean.WareDTO, Bean: org.cts.web.bean.WareDTO, property: taxBase, newValue: 1,newValue class: java.lang.Long method parameter class: java.math.BigDecimal, argument type mismatch
Or if i input decimal value - 1.5 i get ... newValue: 1.5,newValue class: java.lang.Double method parameter class: java.math.BigDecimal, argument type mismatch.
Any suggestions?
