HTML form input value via client side
Hi,
how can I set a value of any input field client side and have it transfered
properly to the backend.
I've tried many different approaches, like hidden input fields and such, but
"value" is mandatory within the tml, it has to be a proper tml/java
object/variable, but thats not what I want, I want to set it client side and
then post the value to the server. Mission impossible?
thanks

Or do you mean via JavaScript and Prototype, e.g. $('myTextFieldID').value = 'whatever';

Yes, the value parameter is mandatory. That' tells Tapestry where to store the value. As noted earlier you can use regular HTML input fields to avoid this, but then you need to extract the value on the server yourself.

Tapestry wouldn't be very useful if you couldn't transfer client input. However, there are a few ways of doing it depending on what the goal is.

Your sentence above doesn't compute. tml itself has nothing mandatory
besides being valid XML. Please post your attempts, otherwise we can only
guess what was wrong with them. You probably used the TextField component.
For example:
<t:textfield value="someProperty"/>
@Property
private String someProperty;

tml itself doesn't have objects.

Absolutely not. Just provide use more information on how you tried to
implement and we'll help you.

PS. My memory is rusty, it might also be the getAttribute() method, but try
getParameter() first.

Try using a normal HTML input (non-T5 component, could be the hidden one
you mentioned) and then:
import org.apache.tapestry5.services.Request;
...
@Inject private Request request;
...
request.getParameter("name");
