> I want to be able to specify a clientId so that tapestry doesn't auto-generate one for
me. This works on many core tapestry components when I specify an "id" because the following
code is present:
> {code}
> clientId = resources.isBound("id") ? idParameter : renderSupport.allocateClientId(resources);
> {code}
> But in AbstractField, this logic is different
> {code}
> @Parameter(value = "prop:componentResources.id", defaultPrefix = BindingConstants.LITERAL)
> private String clientId;
> final void setup() {
>    String id = clientId;
>    ...
>    assignedClientId = jsSupport.allocateClientId(id);
> }
> public final String getClientId() {
>    return assignedClientId;
> }
> {code}
> This means that tapestry will generate id's like "foo_af42a49d19a" after zone updates
when I set clientId to "foo". This makes it impossible to attach clientside behaviour by field
id selectors.
> As a workaround, I add "data-" attributes to my fields and select by them instead. I
assume this has worse performance than id based selectors.
