custom validator exception
Hi All,
I am trying to create a custom validator which will take values from 2
HtmlInputText components and compare whether "date1" is greater or
lesser than "date2" and then proper messages on the page.
When I run the application the following exception is thrown:

Any help on why this exception has occurred?
The Validator class implements Validator and StateHolder interfaces.
In the validate method I am retrieving the components with id's passed
in as attributes to the component. Once I get the components then
validations can be done.
Thanks,
madhav

Re: custom validator exception
Posted by Matthias Wessendorf <ma...@apache.org>.
the error says the component you nest it is no ValueHolder.
not related to the validator.
inside of tomahawk there is a similar validator. <t:validateEquals /> check
that code and *convert* the logic to your use case.
Trinidad has also two validators for dates (dateRange and dateRestriction)
Greetz,
