Dynamic Validator Parameters
This may be a very easy question, but I've looked around and can't
find the right way to do this. All I want to be able to do is set a
validator parameter like "max" for example to the value of a page
property instead of a hard-coded number. So I kinda want to do like
"max=ognl:maxValue". What's the right way to do this?

This would work for custom validators. What I want to know is how can
I bind values to the standard validators such as specifying the
maximum length of a string or the max value of an integer using
existing validators but just get the actual numeric constraint from a
property rather than hard-coding it. In my opinion there should be
some notation within the validators: prefix (similar to using $ for
referring to beans) but that refers to an ognl expression or at the
very least a simple property name. I just wanted to make sure there is
no standard easy way of doing this before I go and write my own
validator.

Actually it is validators=validators:$maxBean
Then in your bean's validate(...), you can access any page property that
way:
YourPage page = (YourPage) field.getPage();
YourPropertyType value = page.getYourProperty();

Define the max validator class as a bean and reference it instead of max=<?>
(ie validators="validators:maxBean" i think, maybe it's more complicated
than that)
