Overwriting framework error messages of simple types

Question

Hi
Is it possible to overwrite the framework error messages of simple types? For example: Instead of "Enter the value in the format -2,733.34" we prefer something like "Enter the percent value in the format 0.00 to 100." or "Enter a correct percent value.".
Use case: We use for the most input fields for any numbers (telefon, amount, age, ...) the simple type "decimal", this offers following advantages:
- optional use (and framework validation) of fraction digits
- the input field has no default value (integer/long/short writes as default "0" to the input field, that is in most cases - for example post/zip code - not useful)
Otherwise decimal simple types has the disadvantage, that if the user write any letters in the (decimal) input field, the error message is as described above and so not very helpful too.
Thanks in advance

Hi Stefan
Unfortunately seems no way to customize the error messages.
1. If the standard numeric simple type does not suit your needs, theoretically you can try to override the Java class of the standard type and add your custom messages/logic. For example, for Integer this is DdTypeInteger & DdTypeInt. Methods you need to override is format(...) and parse(...). After this in controller's code you should create a new attribute and provide your own custom type as input parameter.
I never tried this way
2. You can make the attribute as Calculated. Then in getter/setter you should put your custom formatting/parsing logic.
