Two arguements in validate parameter

[George Christman <gc...@cardaddy.com>]

Hello, I'm trying add the following arguments to the tapestry validate
parameter. The first one being tapestry's built in email validator and the
second being my custom validator. 

t:validate="email, prop:getFieldValidator('shiptoContactEmail')"

which results in this exception. 

java.lang.RuntimeException
Unexpected character ':' at position 12 of input string: email,
prop:getFieldValidator('shiptoContactEmail')

In a previous post, Robert said 

"Specifying the property prefix (eg: prop:, component:, validate:, etc.)
only
works at the beginning of the expression, and it is applied to the entire
expression. "

which would explain the exception, however I'm wondering how this should be
done. Should I pass back email in the fieldValidator and handle it on the
backend or is there another way to handle this on the frontend. 

Thanks,

The validator binding doesn't support property expressions. In other  
words, you should add the email validation in the getFieldValidator()  
method instead.
