How to reset a form enclosed in a zone from the java-side handler?
I have a form enclosed in a zone. When I submit the form with my register
button, it's being handled by method:
private Object onSelectedFromRegister() {
...
return zone;
}
The default behaviour seems to be that when the zone gets re-rendered the
UI form fields retain their submitted post values client side.
What I'd like to be able to do is, in my register handler (see above), i'd
like to null out all of the form fields next time the zone re-rerenders.
In my form I have a text field component that's bound to a page property
that has no persistence. So it's just like a regular instance variable in
my page class. How can I (javaside) reset the form (or just the textfield)
w/o writing javascript? I've tried injecting the form and the textfield
components, but found no useful methods there. And nulling out the instance
variable does nothing in this regard either.
any suggestions/ clues much appreciated.
thanks

I'd recommend using Form's normal events. See:
http://jumpstart.doublenegative.com.au/jumpstart/examples/ajax/whatiscalledandwhen
or for T5.4:
http://jumpstart.doublenegative.com.au/jumpstart7/examples/ajax/whatiscalledandwhen
Instead of returning the zone from onSelected, return it from onSuccess and, if errors are possible, onFailure. Then in onPrepareForRender set the form values to whatever defaults you want.
