allow for me, so, at first glance, no ajax can be used at my pages.
The J in AJAX is Javascript, so you cannot *rely* on Javascript, but you
use it, as long as your pages still work with Javascript disabled. With
Request.isXHR(), it's easy to do that.
As i have checked in the books, there are a couple of ways: use @Persist
for the resultset, @Persist("flash") or passivate and activate. We want
to avoid the first way, for session size. The second way works great,
but the last one doesn't work (or at leas, we cannot make it works).
@Persist("flash") the form fields, not the resultset. ;)
Instead of doing the search in your action request, do that in the render
request (don't forget that T5 uses redirect-after-post unless you
explicitly turn it off, and you shouldn't):
@Persist("flash")
private String field1;
@Persist("flash")
private String field2;
public List<Result> getResults() {
return search(field1, field2); // where search is a method that does the
search
}
<table t:type="Grid" t:source="results">
...
</table>
One fact that is ofter overlooked is that the form is submitted and page
field's values set *even when you don't have a method listening* to the
form events. ;)
I hope it helps. :)
