That looks very interesting. I'ĺl look into that and see if i can get it
to work.
Thanks Igor.

an easy way to do this is to key both repeaters off the same model:
class mypage extends webpage {
class resultsmodel extends loadabledetachablemodel {
load() { return solr.search(...); }
}
mypage() {
setmodel(new resultsmodel());
add(new listview("a", getmodel()));
add(new listview("b", getmodel()));
}
}
that way both repeaters are reusing the same cached result.

Dear Wicket Users,
I have a slight problem, although problem might not be the correct word.
I'll explain.
I'm developing an application which allows the searching of metadata
from scanned documents. For searching i'm using Solr and for the
frontend i'm using Wicket. Both are new technologies to me and i'm
having a lot of fun learning both. However, my implementation of the
search page just doesn't feel exactly right. I was hoping to get some
advice here about how to proceed.
Solr has the ability to give me facets, which you can use to refine a
search. That is a feature i want, but it also adds a problem.
You search once, but get two different results. The first is the series
of documents matching the search criteria, the second a list of facets
about the documents in the search results. So, how do i only search
once, and populate two different repeaters. Sofar i've done this in
three different ways, but i'm not happy with either.
1. I've used a DataView for both the document list and the facet list.
Both with a DataProvider doing the search and returning a subset. Where
the facet list always returning the complete list.
Eventhough this is easy to implement, it also makes me search twice for
the same query, which is something i try to avoid. However my experience
with solr is still very limited, so i'm not sure if this is that much of
a problem in the end. But sofar i've been trying to avoid the double
search.
2. My second try was by doing the search in the onBeforeRender method.
Creating a new Pageable list for the documents and a normal ListView for
the facets and then using addOrReplace to get them on the page.
This is working just fine and i'm only doing one search. Except i've got
this feeling that i'm not supposed to alter the components in the
'onBeforeRender' method. I could be wrong, but it just doesn't feel right.
3. I create a new page for every request with a different Query Object.
So the page does the search, fills the list and displays it. Rewrite
every link to construct a new SearchPage and show that one.
The problem i'm having with this one is the constant contruct of new
SearchPages. I should be reusing them.
Due to my inexperience with Wicket i'm kind of at a loss on how to
proceed and hope i can get some advice. So i guess my question comes
down to, what is the proper way to populate two lists from one source,
while still being able to modify the search criteria.
I hope someone can give me some advice.
Regards,
Nicky
