Hello Miguel;
The pager rendering is not a dramatic computational process, but
it requires some queries to the database to know how much items to
page, and in some situations some objects that are being paged.
So, I would like to avoid doing that twice.
Of course, I can have solve this at the controller level, making
sure that the calls are only executed once per RR loop, etc. But
I'm thinking, this is WO, so there's probably a better way. And
the better way would be to, of course, copy the rendered HTML of
the pager to the second location of the page. I'm actually not
sure if this a better way (my "elegance VS pragmatism" eternal
philosophical questions) but anyway, how would this be done in WO?
BTW this is supposed to work on AjaxUpdateContainers, so the
solution would have to support that
Could you cache intermediate query results in the info dictionary
of the generated response message?
If wonder if you did something like this:
private String renderedHTML;
public void appendToResponseInContext(WOResponse r, WOContext c) {
if (renderedHTML != null) {
r.appendContentString(renderedHTML);
renderedHTML = null;
} else {
WOResponse componentResponse = new WOResponse()
super.appendToResponseInContext(componentResponse, c);
renderedHTML = componentResponse.contentString();
r.appendContentString(renderedHTML);
}
}
