in fact, shale's converter converts my 12345 number to "123.45" string...
but this is the normal behaviour.. my locale's grouping character used while
generating string value from integer value... this is same as jsf ri
converter's behaviour... Issue raiser is C-V's GenericTypeValidator not
concerning default locale while validating "123.45" string value...

GenericTypeValidator has two formatInt method:
1- formatInt(String value) : no locale specified.. so it works as "return
new Integer(value);"
2- formatInt(String value, Locale locale) : uses provided locale while
formatting value. if locale is not provided, uses default locale to format
the value...

integer validator uses the 1. method.. as a result it throws a
numberformatexception at line "return new Integer(value);" (value="123.45
")..
if 1.method use the 2. method with null locale parameter.. it would format
my value according to the default locale and there would be no problem...
my solutioun: 1. method should use 2.method with null locale parameter
instead of "new Integer(value)" conversion....

hope i've cleared the issue....

regards,

hasan..
