Re: Mutually dependent component and how to update a textfield when a link is clicked

[John Krasnay <jo...@krasnay.ca>]

Hi Liam,

Check out this page:

http://cwiki.apache.org/WICKET/conditional-validation.html

It has a bunch of recipes for interactions between components, e.g.
requiring a text field only if a checkbox is checked or a certain submit
button was used. Sounds similar to what you need to do.
