Hello!
Ben already provided some great options, as usual. :) I'll add another:
what about using links with the EventLink component, all of them using the
same event name but with different contexts, all of them styled as buttons?
Does it really need to be an <input>? Something like this (not tested):
<t:loop source="buttons" value="paneButton">
<t:eventLink t:event="buttonClicked" t:context="paneButton" class="btn
${buttonStyling}">${buttonLabel}</eventLink>
</t:loop>
Object onButtonClicked(String paneButton) {
...
}
Tapestry's Submit component really wasn't meant to be used inside a loop
while having a context and being able to get it (context) on the
corresponding component/page/mixin/page class. And I'm not sure it could be
changed to have passing its context work without JavaScript.
In your original code above, have you tried adding the name attribute to
your <input>s, all them with the same value, and then getting the value
from Request.getParameter() or @RequestParameter?
