There is a session bean (I've tried statefull and stateless) called SearchManagerBean (component name searchManager)
The request parameter is injected and there is a getter, plus one method:
@RequestParameter
String queryString;
public String getQueryString() {
return queryString;
}
public String search() {
return "/nodeList.xhtml";
}
When rendering nodeList.xhtml, there is a `nodes' component, supplied by the @Factory method in another bean, NodeManagerBean:
@In(create=false, required=false)
SearchManager searchManager;
@Factory("nodes")
public void findNodes() {
StringBuffer q = "FROM Node";
if(searchManager != null)
q = "FROM Node WHERE name LIKE '%" + searchManager.getQueryString() + "%'";
nodes = em.createQuery(q).getResultList();
}
The problem I face is this:
- in the search() method of SearchManagerBean, the value of queryString is useable
- however, when searchManager.getQueryString() is called from the @Factory method in NodeManagerBean, the searchManager instance that has been injected says that the parameter is null
One solution I found was making the SearchManagerBean scope CONVERSATION, however, this means that the search parameter is used every time the nodeList is fetched - that is not what I want. I only want the parameters to hang around for long enough to render the page.
I also tried encapsulating the queryString in another JavaBean, with scope PAGE, that didn't work either.
