JBO-27010: Attribute set ... has invalid precision/scale

Question

We have created a table ACCOUNT with a column RATE defined as NUMBER(5, 3).
Bc4j has created the corresponding entity object Account with:
<Attribute
Name="Rate"
Type="oracle.jbo.domain.Number"
ColumnName="RATE"
ColumnType="NUMBER"
SQLType="NUMERIC"
IsNotNull="true"
Precision="5"
Scale="3"
TableName="ACCOUNT" >
Also the corresponding view object AccountView has been created.
Here is the java code (JDeveloper Ver.3.2.3) where we catch an exception:
ViewObject vo = applicationModule.findViewObject("AccountView");
Row r = vo.createRow();
String rateStr = "12,725"; // comma used locally as decimal separator
oracle.jbo.domain.Number rateN = new oracle.jbo.domain.Number(rateStr);
r.setAttribute("Rate", rateN);
The exception is:
oracle.jbo.AttrSetValException: JBO-27010: Attribute set with value 12,725 for Rate in Account has invalid precision/scale
Any help would be greatly appreciated.
Thanks in advance.

I like to tell you that now everything is ok.
Looking at the libraries included in my project, I found an unecessary library "JBO Generic Domains" (X:\Program Files\Oracle\JDeveloper 3.2.3\lib\jbodomgnrc.zip) containing a class oracle.jbo.domain.Number different from the right one in "JBO Oracle Domains" (X:\Program Files\Oracle\JDeveloper 3.2.3\lib\jbodomorcl.zip).
