Or can I let clicking the link generate an event which then will be picked
up by the component
you can, but is an workaround:
1 - add AjaxFormComponentUpdatingBehavior on your textarea for 'metal' event
2 - add
eval(Wicket.$('mytextareamarkupid').getAttribute('metal'))
on 'onclick' event of your link
But... seems very natural require the user submit the form that contains the
textarea.
