I believe that's the issue: if you return null in onActivate(), you're
telling Tapestry to render the template, as you didn't provide any other
answer to the request by returning an object. If you really don't need to
provide any answer to the request, just return new
TextStreamResponse("text/plain, "") instead.
Also, calling Response.sendRedirect() in an event handler method, like you
did in onFilter(), is asking for trouble. You should return some object
(java.net.URL, page instance, page class, etc) telling Tapestry where to
redirect instead.
public abstract class BaseCatalogPage {
private static final SearchRequest NULL_REQUEST = new
SearchRequest(){
@Override
public Map<String, String> getSortModel() {
return Collections.emptyMap();
}
};
protected static final Future<SearchRequest> NULL_FUTURE_REQUEST =
new Future<SearchRequest>() {
@Override
public boolean cancel(boolean mayInterruptIfRunning) {
return false;
}
@Override
public boolean isCancelled() {
return false;
}
@Override
public boolean isDone() {
return true;
}
@Override
public SearchRequest get() throws InterruptedException,
ExecutionException {
return NULL_REQUEST;
}
@Override
public SearchRequest get(long timeout, @NotNull TimeUnit unit)
throws InterruptedException, ExecutionException, TimeoutException {
return NULL_REQUEST;
}
};
@ActivationRequestParameter
private int page;
@ActivationRequestParameter
private String direction;
@ActivationRequestParameter
private String sort;
private CachedProduct[] products;
private Future<SearchRequest> searchRequestFuture =
NULL_FUTURE_REQUEST;
public class FacetFilter {
public void onFilter(@RequestParameter(value = "direction", allowBlank =
true) String direction,
@RequestParameter(value = "sort", allowBlank =
true) String sort,
@RequestParameter(value = "q", allowBlank =
true) String q,
@RequestParameter("uri") String uri) throws
IOException {
Request request = this.request;
if (StringUtils.isNotEmpty(uri)) {
StringBuilder sb = new StringBuilder(uri).append('?');
SortOrder order = SortOrder.ASC.name().equals(direction) ?
SortOrder.ASC : SortOrder.DESC;
MutableBoolean addSort = new MutableBoolean(false);
Category category;
if("/search".equals(uri)) {
sb.append("q").append('=').append(q).append('&');
for(SearchFacet searchFacet :
searchFacetDao.readAllSearchFacets()){
build(request, sb, sort, addSort, searchFacet);
}
redirect(request, response, sb, sort, order, addSort);
} else if ((category = catalogService.findCategoryByURI(uri))
!= null) {
for(CategorySearchFacet categorySearchFacet :
category.getSearchFacets()){
build(request, sb, sort, addSort,
categorySearchFacet.getSearchFacet());
}
redirect(request, response, sb, sort, order, addSort);
}
}
}
private void redirect(Request request, Response response, StringBuilder
sb, String sort, SortOrder order, MutableBoolean addSort) throws

String page;

sb.append("page").append('=').append(page).append('&');
}

sb.append("sort").append('=').append(sort).append('&').append("direction").append('=').append(order.name());
} else {
sb.deleteCharAt(sb.length() - 1);
}
response.sendRedirect(sb.toString());
}
When the the Request is Posted it is looking for properties on the
FacetFilter that are only relevant if it were to render an html result

Subject: Re: Problem with POST requests
Hi!
Could you please post the code of your component and the page? I'm
having a
hard time understanding your scenario from your description.
Are you using a component or page as code that will upload something
to ElasticSearch when it is requested but not sending any response
back to the browser?

I'm using Elasticsearch, my first implementation involved processing a
user request (verifying that there facet filters are valid) in the
request chain and then sending a redirect short circuiting the request
pipeline. Now here's the problem. I moved the processing into a
component to make it more modular and way less fragile. The problem is
the actual search/facet filter happens during the GET request and it is
injected into the EventContext and when they hit the page the request
result is assigned in the onActivate event. The problem is on the POST
request the page components are still looking for those values as if it
was trying to render the template. I just did a workaround and made a
NullSearchRequest value but it just seems like a hacky workaround and I
keep having to check if a value is null for properties that are never
called on that are never used in a POST request. Anyone know a good
work around?
