trying to display components updated by an AJAX request
I'm having difficulty displaying a component after it's updated by an AJAX request. The component is session scoped and is below:
@Scope(ScopeType.SESSION)
@Name("searchResultsBean")
public class SearchResultsBean {
private List<SearchResult> searchResults = new ArrayList<SearchResult>(0);
private List<SearchFacet> searchFacets = new ArrayList<SearchFacet>(0);
private List<SearchDateFacet> searchDateFacets = new ArrayList<SearchDateFacet>(0);
public Integer getDreamIdForMatch() {
return dreamIdForMatch;
}
public void setDreamIdForMatch(Integer dreamIdForMatch) {
this.dreamIdForMatch = dreamIdForMatch;
}
private Integer dreamIdForMatch;
public List getSearchFacets() {
return searchFacets;
}
public List getSearchDateFacets() {
return searchDateFacets;
}
public List getSearchResults() {
return searchResults;
}
public void clear() {
searchResults.clear();
clearFacets();
}
public void clearFacets() {
searchFacets.clear();
}
public void addFacet(SearchFacet facet) {
searchFacets.add(facet);
}
public void addFacet(long count, String facetName, String fq) {
searchFacets.add(new SearchFacet(count, facetName, fq));
}
public void addDateFacet(SearchDateFacet f) {
searchDateFacets.add(f);
}
public void addSearchResult(String id, String name, String description,
Date date, String tag) {
searchResults.add(new SearchResult(
id,
name,
description,
date,
tag
));
}
public void addDateFacet(long count, String facetName, String fq) {
searchDateFacets.add(new SearchDateFacet(count, facetName, fq));
}
}
The SLSB method that is called by AJAX and updates the SearchResultsBean component is below:
public boolean matchDream(Integer userId, Integer dreamId) {
//Conversation.instance().setViewId("/DreamMatches2.xhtml");
searchResultsBean.clear();
List<Dream> dreamsForUser = dreamList.getDreamsForUserId(userId);
Dream dream = dreamList.getDream(dreamId);
String queryString =
createQuery(solrEscape(dream.getDescription()), dreamsForUser);
//System.out.println("match query: " + queryString);
SolrQuery query = new SolrQuery();
query.setRows(3);
try {
//query.setQuery(queryTerm);
query.setQuery(
queryString);
}
catch (Exception exc) {
log.error("error setting query", exc);
}
try {
if (server == null) server = new CommonsHttpSolrServer(solrHost);
}
catch (Exception exc) {
log.error("error querying Solr host", exc);
}
QueryResponse resp = null;
//System.out.println(queryString);
try {
resp = server.query(query);
}
catch (Exception exc) {
log.error("error querying search server", exc);
}
SolrDocumentList docs = resp.getResults();
Iterator<SolrDocument> iter = docs.iterator();
while (iter.hasNext()) {
SolrDocument resultDoc = iter.next();
String tags = (String) resultDoc.getFieldValue("tag");
String dv = (String) resultDoc.getFieldValue("dreamvalue");
Date dreamDate = (Date)resultDoc.getFieldValue("dreamdate");
String dn = (String) resultDoc.getFieldValue("dreamname");
Integer did = (Integer) resultDoc.getFieldValue("dream_id"); //id is the uniqueKey field
//System.out.println("in!!!!!!!!!!!!!");
searchResultsBean.addSearchResult(
String.valueOf(did),
dn,
dv,
dreamDate,
tags
);
}
searchResultsBean.setDreamIdForMatch(dreamId);
return true;
}
The xhtml with the AJAX call and component rendering is below. My problem (which is probably a simple misunderstanding on my part) is that the SearchResultBean in the datatablepanel rich panel won't display. It is supposed to display a data table of components (dreams) populated by the searchResultsBean.getSearchResults() method. If I simply reload the page, the search results show up correctly. Any help is appreciated.
<a:region id="theregion">
<a:form id="theform" ajaxSingle="true" reRender="datatablepanel">
<a:commandButton id="Match"
value="Match!"
action="#{searchBean.matchDream(user.userId, _dream.dreamId)}"
/>
<rich:panel id="datatablepanel">
<h:dataTable id="results2" var="_searchResult" value="#{searchResultsBean.getSearchResults()}">
<h:column>
<s:link value="#{_searchResult.name}" view="/DreamSearchItem.xhtml">
<f:param name="id" value="#{_searchResult.id}"/>
</s:link>
</h:column>
</h:dataTable>
</rich:panel>
</a:form>
<a:status>
<f:facet name="start">
<h:graphicImage value="img/aprocessing.gif"/>
</f:facet>
</a:status>
</a:region>
