Variable validation

[Denis Souza <ds...@sti.com.br>]

Hi,

 

I have an input field that needs to be validated like this:

 

validators="validators:required,min=1,max=X"

 

where X is a value that will be different whenever the page is loaded.
However, at least as far as I know, tapestry's validation mechanism only
allows you to set X to a static value. Anyone know a way I can make this
work?

 

Thanks,
Denis

Max is standard validator, so as any validator it should be a POJO.
So, you probably can get it as bean and set your custom value with OGNL.
If it will not work, you always can create your custom validator ( it is 
easy ),
instantiate it as bean on your page ,set all required values for that 
bean and then
use it as validator.
