           Summary: Double & Float Validator Problems with numbers less than
                    0
           Product: Struts
           Version: 1.1 Final
          Platform: PC
        OS/Version: other
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Validator Framework
        AssignedTo: dev@struts.apache.org
        ReportedBy: cathy.primm@dnr.mo.gov


I have an application which requires input of numbers less than 0.  They are 
ususally entered e.g. .45 or .4 and redisplay as e.g. 0.45 or 0.4 for an update.

When I use the ValidateDOUBLE validator to assure they will convert to DOUBLES, 
both .45 and 0.45 return the "must be double(numeric)" error.

A teacher in a recent STRUTS class suggested I change the validator to the 
ValidateFLOAT validator instead of ValidateDOUBLE.  I tried this and it is 
better but I'm still finding a bug (or at least I believe it is a bug).  If the 
the number is entered e.g. 0.49 - I get the "must be float(numeric)" error;  if 
0.4 - it's OK; if .4 it's OK; if it's .49, it's OK.

Am I not understanding these validators (possible as I'm a newbie) or is this a 
bug you can help me with?  Thanks for any help/enlightenment you can provide.

This problem is in a system in the user system testing stage that will enter 
many such numbers.  We can program around it by adding a validation for numeric 
to the action but using the STRUTS validator is much more efficient if we can 
get it to work.
