Well, making that change gave another exception: "No validator named 'string' has been defined."
So, since the "string" validator was not defined I just left it with "required" and it worked. I saw it work but I don't quite get it. Please help me understand this: The docs say that the proper way to use a validator is with the syntax: validator:name[,property[=value]]* Which would make it valid for me to use: validator:string,required String, being the validator and "required" being one of the validator's properties. If this has changed so that I must now use the prefix "validatorS" and the commas to separate between different validators, instead of different properties for a single validator, how is it that I can pass along any needed properties to a validator? For example: If I have a validator called "MyValidator" and I want to set two properties in this validator (prop1 and prop2), how would I do that? I just noticed that all validators present in the Tapestry 4 framework take only one property and the property always has the same name as the validator itself.
